+
+## Installation (AUR)
 
 ```bash
-# Install hyprvoice and all dependencies automatically
 yay -S hyprvoice-bin
 # or
 paru -S hyprvoice-bin
 ```
 
-The AUR package automatically installs all dependencies (`pipewire`, `wl-clipboard`, `wtype`, etc.) and sets up the systemd service. Follow the post-install instructions to complete setup.
+The package installs system dependencies and the systemd user service.
-
+You'll still need an API key for a cloud provider, or whisper.cpp for local transcription. Onboarding will guide you through the choice.
-### Alternative: Download Binary
-
-For non-Arch users or testing:
-
-```bash
-# Download and install binary
-wget https://github.com/leonardotrapani/hyprvoice/releases/latest/download/hyprvoice-linux-x86_64
-mkdir -p ~/.local/bin
-mv hyprvoice-linux-x86_64 ~/.local/bin/hyprvoice
-chmod +x ~/.local/bin/hyprvoice
-
-# Add to PATH (add to ~/.bashrc or ~/.zshrc)
-export PATH="$HOME/.local/bin:$PATH"
-
-# You'll need to manually install dependencies and create systemd service
-# See Requirements section above
-```
-
-### Build from Source
-
-```bash
-git clone https://github.com/leonardotrapani/hyprvoice.git
-cd hyprvoice
-go mod download
-go build -o hyprvoice ./cmd/hyprvoice
-
-# Install locally
-mkdir -p ~/.local/bin
-cp hyprvoice ~/.local/bin/
-export PATH="$HOME/.local/bin:$PATH"
-```
-
-## Requirements
-
-- **Wayland desktop** (Hyprland, Niri, GNOME, KDE, etc.)
-- **PipeWire audio system** with tools
-- **API key for transcription**: OpenAI, Groq, Mistral, or Eleven Labs API key (check each provider's pricing)
-
-**System packages** (automatically installed with AUR package):
-
-- `pipewire`, `pipewire-pulse`, `pipewire-audio` - Audio capture
-- `wl-clipboard` - Clipboard integration
-- `wtype` - Text typing (Wayland)
-- `ydotool` - Text typing (universal, recommended for Chromium apps)
-- `libnotify` - Desktop notifications
-- `systemd` - User service management
-
-For manual installation on other distros:
-
-```bash
-# Ubuntu/Debian
-sudo apt install pipewire-pulse pipewire-bin wl-clipboard wtype ydotool libnotify-bin
-
-# Fedora
-sudo dnf install pipewire-utils wl-clipboard wtype ydotool libnotify
-
-# For ydotool, you also need to start the daemon:
-systemctl --user enable --now ydotool
-# Or add user to input group for uinput access:
-sudo usermod -aG input $USER
-```
 
 ## Quick Start
 
-After installing via AUR:
+1. Run onboarding:
 
-1. **Configure hyprvoice interactively:**
 ```bash
-hyprvoice configure
+hyprvoice onboarding
 ```
-This wizard will guide you through setting up your transcription provider, API key, audio preferences, and other settings.
 
-2. **Enable and start the service:**
+2. Enable and start the service:
+
 ```bash
 systemctl --user enable --now hyprvoice.service
 ```
 
-3. **Add keybinding to your window manager:**
+3. Add a keybinding (Hyprland example):
+
 ```bash
-# For Hyprland, add to ~/.config/hypr/hyprland.conf
 bind = SUPER, R, exec, hyprvoice toggle
 ```
 
-4. **Test voice input:**
+4. Test voice input:
 
 ```bash
-# Check daemon status
-hyprvoice status
-
-# Toggle recording (or use your keybind)
 hyprvoice toggle
-# Speak something...
-hyprvoice toggle  # Stop and transcribe
 ```
 
-## Quick Reference
+Run `hyprvoice configure` anytime for advanced settings.
 
-### Common Commands
+## Commands
+
+### Core CLI
 
 ```bash
-# Interactive configuration wizard
+hyprvoice onboarding
 hyprvoice configure
-
-# Start the daemon
 hyprvoice serve
-
-# Toggle recording on/off
 hyprvoice toggle
-
-# Cancel current operation
 hyprvoice cancel
-
-# Check current status
 hyprvoice status
-
-# Get protocol version
 hyprvoice version
-
-# Stop the daemon (if not using systemd service)
 hyprvoice stop
 ```
 
-### Keybinding Pattern
+### Model management (whisper-cpp)
-
-Most setups use this toggle pattern in window manager config:
 
 ```bash
-bind = SUPER, R, exec, hyprvoice toggle
+hyprvoice model list
-bind = SUPER SHIFT, R, exec, hyprvoice cancel  # Optional: cancel current operation
+hyprvoice model list --provider whisper-cpp
+hyprvoice model download base.en
+hyprvoice model remove base.en
 ```
 
-## Keyboard Shortcuts Setup
+### Model testing (E2E)
-
-### Hyprland
-
-Add to your `~/.config/hypr/hyprland.conf`:
 
 ```bash
-# Hyprvoice - Voice to Text (toggle recording)
+hyprvoice test-models
-bind = SUPER, R, exec, hyprvoice toggle
+hyprvoice test-models --audio /path/to/sample.wav --output test-models.json
-
-# Optional: Cancel current operation
-bind = SUPER SHIFT, C, exec, hyprvoice cancel
-
-# Optional: Status check
-bind = SUPER SHIFT, R, exec, hyprvoice status && notify-send "Hyprvoice" "$(hyprvoice status)"
 ```
 
-## Usage Examples
+### Service management
-
-### Basic Toggle Workflow
-
-1. **Press keybind** → Recording starts (notification appears)
-2. **Speak your text** → Audio captured in real-time
-3. **Press keybind again** → Recording stops, transcription begins
-4. **Text appears** → Injected at cursor position or clipboard
-
-**Cancel anytime:** Press your cancel keybind (e.g., `SUPER+SHIFT+C`) to abort the current operation and return to idle.
-
-### CLI Usage
 
 ```bash
-# Start daemon manually (if not using systemd service)
+systemctl --user status hyprvoice.service
-hyprvoice serve
+systemctl --user restart hyprvoice.service
-
+journalctl --user -u hyprvoice.service -f
-# In another terminal: toggle recording
-hyprvoice toggle
-# ... speak ...
-hyprvoice toggle
-
-# Check what's happening
-hyprvoice status
 ```
 
 ## Configuration
 
-Use the interactive configuration wizard:
+Configuration lives in `~/.config/hyprvoice/config.toml` and hot-reloads automatically.
 
-```bash
+- First-time setup: `hyprvoice onboarding`
-hyprvoice configure
+- Full TUI editor: `hyprvoice configure`
-```
 
-This will guide you through setting up:
+## Docs
 
-- OpenAI API key for transcription
+- `docs/config.md` - configuration reference and examples
-- Language preferences (auto-detect or specific language)
+- `docs/providers.md` - provider and model details
-- Text injection method (clipboard/typing/fallback)
+- `docs/architecture.md` - architecture and adapter overview
-- Notification settings
+- `docs/structure.md` - code map and entry points
-- Recording timeout
+- `docs/testing.md` - integration testing with test-models
-
-Configuration is stored in `~/.config/hyprvoice/config.toml` and can also be edited manually. Changes are applied immediately without restarting the daemon.
-
-### Transcription Providers
-
-Hyprvoice supports multiple transcription backends:
-
-#### OpenAI Whisper API
-
-Cloud-based transcription using OpenAI's Whisper API:
-
-```toml
-[transcription]
-provider = "openai"
-api_key = "sk-..."              # Or set OPENAI_API_KEY environment variable
-language = ""                   # Empty for auto-detect, or "en", "es", "fr", etc.
-model = "whisper-1"
-```
-
-**Features:**
-- High-quality transcription
-- Supports 50+ languages
-- Auto-detection or specify language for better accuracy
-
-#### Groq Whisper API (Transcription)
-
-Fast cloud-based transcription using Groq's Whisper API:
-
-```toml
-[transcription]
-provider = "groq-transcription"
-api_key = "gsk_..."             # Or set GROQ_API_KEY environment variable
-language = ""                   # Empty for auto-detect, or "en", "es", "fr", etc.
-model = "whisper-large-v3"      # Or "whisper-large-v3-turbo" for faster processing
-```
-
-**Features:**
-- Ultra-fast transcription (significantly faster than OpenAI)
-- Same Whisper model quality
-- Supports 50+ languages
-- Free tier available with generous limits
-
-#### Groq Translation API
-
-Fast translation of audio to English using Groq's Whisper API:
-
-```toml
-[transcription]
-provider = "groq-translation"
-api_key = "gsk_..."             # Or set GROQ_API_KEY environment variable
-language = "es"                 # Optional: hint source language for better accuracy
-model = "whisper-large-v3-turbo"
-```
-
-**Features:**
-- Translates any language audio → English text
-- Ultra-fast processing
-- Language field hints at source language (improves accuracy)
-- Always outputs English regardless of input language
-
-#### Generated Configuration Example
-
-The daemon automatically creates `~/.config/hyprvoice/config.toml` with helpful comments:
-
-```toml
-# Hyprvoice Configuration
-# This file is automatically generated with defaults.
-# Edit values as needed - changes are applied immediately without daemon restart.
-
-# Audio Recording Configuration
-[recording]
-  sample_rate = 16000          # Audio sample rate in Hz (16000 recommended for speech)
-  channels = 1                 # Number of audio channels (1 = mono, 2 = stereo)
-  format = "s16"               # Audio format (s16 = 16-bit signed integers)
-  buffer_size = 8192           # Internal buffer size in bytes (larger = less CPU, more latency)
-  device = ""                  # PipeWire audio device (empty = use default microphone)
-  channel_buffer_size = 30     # Audio frame buffer size (frames to buffer)
-  timeout = "5m"               # Maximum recording duration (e.g., "30s", "2m", "5m")
-
-# Speech Transcription Configuration
-[transcription]
-  provider = "openai"          # Transcription service: "openai", "groq-transcription", or "groq-translation"
-  api_key = ""                 # API key (or set OPENAI_API_KEY/GROQ_API_KEY environment variable)
-  language = ""                # Language code (empty for auto-detect, "en", "it", "es", "fr", etc.)
-  model = "whisper-1"          # Model: OpenAI="whisper-1", Groq="whisper-large-v3" or "whisper-large-v3-turbo"
-
-# Text Injection Configuration
-[injection]
-  backends = ["ydotool", "wtype", "clipboard"]  # Ordered fallback chain
-  ydotool_timeout = "5s"       # Timeout for ydotool commands
-  wtype_timeout = "5s"         # Timeout for wtype commands
-  clipboard_timeout = "3s"     # Timeout for clipboard operations
-
-# Desktop Notification Configuration
-[notifications]
-  enabled = true               # Enable desktop notifications
-  type = "desktop"             # Notification type ("desktop", "log", "none") -- always keep "desktop" unless debugging
-```
-
-#### whisper.cpp Local (Planned) -> Not yet implemented
-
-Private, offline transcription using local models:
-
-```toml
-[transcription]
-provider = "whisper_cpp"
-model_path = "~/models/ggml-base.en.bin"
-threads = 4
-```
-
-#### Recording Configuration
-
-Audio capture settings:
-
-```toml
-[recording]
-sample_rate = 16000        # Audio sample rate in Hz
-channels = 1               # Number of audio channels (1 for mono)
-format = "s16"             # Audio format (s16 recommended)
-buffer_size = 8192         # Internal buffer size in bytes
-device = ""                # PipeWire device (empty for default)
-channel_buffer_size = 30   # Audio frame buffer size
-timeout = "5m"             # Maximum recording duration (prevents runaway recordings)
-```
-
-**Recording Timeout:**
-
-- Prevents accidental long recordings that could consume resources
-- Default: 5 minutes (`"5m"`)
-- Format: Go duration strings like `"30s"`, `"2m"`, `"10m"`
-- Recording automatically stops when timeout is reached
-
-#### Text Injection
-
-Configurable text injection with multiple backends:
-
-```toml
-[injection]
-backends = ["ydotool", "wtype", "clipboard"]  # Ordered fallback chain
-ydotool_timeout = "5s"
-wtype_timeout = "5s"
-clipboard_timeout = "3s"
-```
-
-**Injection Backends:**
-
-- **`ydotool`**: Uses ydotool (requires `ydotoold` daemon for ydotool v1.0.0+). Most compatible with Chromium/Electron apps.
-- **`wtype`**: Uses wtype for Wayland. May have issues with some Chromium-based apps (known upstream bug).
-- **`clipboard`**: Copies text to clipboard only. Most reliable, but requires manual paste.
-
-**Fallback Chain:**
-
-Backends are tried in order. The first successful one wins. Example configurations:
-
-```toml
-# Clipboard only (safest, always works)
-backends = ["clipboard"]
-
-# wtype with clipboard fallback
-backends = ["wtype", "clipboard"]
-
-# Full fallback chain (default) - best compatibility
-backends = ["ydotool", "wtype", "clipboard"]
-
-# ydotool only (if you have it set up)
-backends = ["ydotool"]
-```
-
-**ydotool Setup:**
-
-ydotool requires the `ydotoold` daemon running (for ydotool v1.0.0+) and access to `/dev/uinput`:
-
-```bash
-# Start ydotool daemon (systemd)
-systemctl --user enable --now ydotool
-
-# Or add user to input group
-sudo usermod -aG input $USER
-# Then logout/login
-
-# For Hyprland, add to config to set correct keyboard layout:
-# device:ydotoold-virtual-device {
-#     kb_layout = us
-# }
-```
-
-**Behavior:**
-
-- Backends are tried in order until one succeeds
-- Include `clipboard` in the chain if you want text copied to clipboard as fallback
-
-#### Notifications
-
-Desktop notification settings:
-
-```toml
-[notifications]
-enabled = true             # Enable/disable notifications
-type = "desktop"           # "desktop", "log", or "none"
-```
-
-**Notification Types:**
-
-- **`desktop`**: Use notify-send for desktop notifications
-- **`log`**: Log messages to console only
-- **`none`**: Disable all notifications
-
-Always keep `type = "desktop"` unless debugging.
-
-##### Custom Notification Messages
-
-You can customize notification text via the `[notifications.messages]` section.
-
-```toml
-[notifications.messages]
-  [notifications.messages.recording_started]
-    title = "Hyprvoice"
-    body = "Recording Started"
-  [notifications.messages.transcribing]
-    title = "Hyprvoice"
-    body = "Recording Ended... Transcribing"
-  [notifications.messages.config_reloaded]
-    title = "Hyprvoice"
-    body = "Config Reloaded"
-  [notifications.messages.operation_cancelled]
-    title = "Hyprvoice"
-    body = "Operation Cancelled"
-  [notifications.messages.recording_aborted]
-    body = "Recording Aborted"
-  [notifications.messages.injection_aborted]
-    body = "Injection Aborted"
-```
-
-### Configuration Hot-Reloading
-
-The daemon automatically watches the config file for changes and applies them immediately:
-
-- **Notification settings**: Applied instantly
-- **Injection settings**: Applied to current and future operations
-- **Recording/Transcription settings**: Applied to new recording sessions
-- **Invalid configs**: Rejected with error notification, daemon continues with previous config
-
-### Service Management
-
-The systemd user service is automatically installed with the AUR package:
-
-```bash
-# Check service status
-systemctl --user status hyprvoice.service
-
-# Start/stop service
-systemctl --user start hyprvoice.service
-systemctl --user stop hyprvoice.service
-
-# Enable/disable autostart
-systemctl --user enable hyprvoice.service
-systemctl --user disable hyprvoice.service
-
-# View logs
-journalctl --user -u hyprvoice.service -f
-```

-## Architecture Overview
-
-Hyprvoice uses a **daemon + pipeline** architecture for efficient resource management:
-
-- **Control Daemon**: Lightweight IPC server managing lifecycle
-- **Pipeline**: Stateful audio processing (recording → transcribing → injecting)
-- **State Machine**: `idle → recording → transcribing → injecting → idle`

-
-### How It Works
-
-1. **Toggle recording** → Pipeline starts, audio capture begins
-2. **Audio streaming** → PipeWire frames buffered for transcription
-3. **Toggle stop** → Recording ends, transcription starts
-4. **Text injection** → Result typed or copied to clipboard
-5. **Return to idle** → Pipeline cleaned up, ready for next session
-
-### Data Flow
-
-1. `toggle` (daemon) → create pipeline → recording
-2. First frame arrives → transcribing (daemon may notify `Transcribing` later)
-3. Audio frames → audio buffer (collect all audio during session)
-4. Second `toggle` during transcribing → send `inject` action → transcribe collected audio → injecting (simulated)
-5. Complete → idle; pipeline stops; daemon clears reference
-6. Notifications at key transitions

-
-### IPC Protocol
-
-Simple single-character commands over Unix socket:
-
-- `t` - Toggle recording on/off
-- `c` - Cancel current operation
-- `s` - Get current status
-- `v` - Get protocol version
-- `q` - Quit daemon gracefully

+# Architecture
+
+This doc describes how the CLI, daemon, pipeline, and adapters compose the system.
+
+## Overview
+Hyprvoice is split into a thin CLI and a long-lived daemon. The CLI sends single-character IPC commands to the daemon. The daemon owns lifecycle and runs a pipeline state machine that coordinates recording, transcription, optional LLM cleanup, and text injection.
+
+## Components
+- CLI: command parsing and IPC client (`cmd/hyprvoice/main.go`).
+- Daemon: IPC server, lifecycle, pipeline ownership (`internal/daemon/daemon.go`).
+- Pipeline: state machine orchestration (`internal/pipeline/`).
+- Recording: PipeWire capture (`internal/recording/`).
+- Transcription: batch + streaming adapters (`internal/transcriber/`).
+- LLM post-processing: adapters and prompt builders (`internal/llm/`).
+- Injection: wtype/ydotool/clipboard backends (`internal/injection/`).
+- Provider registry: model metadata and adapter selection (`internal/provider/`).
+- Config manager: load/validate + hot reload (`internal/config/`).
+
+## IPC control plane
+The daemon listens on a unix socket and accepts single-character commands.
+
+- Socket path: `~/.cache/hyprvoice/control.sock` (see `internal/bus/bus.go`).
+- Command bytes: `t` toggle, `c` cancel, `s` status, `v` version, `q` quit.
+- Responses are line-based: `OK ...`, `STATUS ...`, or `ERR ...`.
+
+The CLI writes one command byte and reads the response; the daemon maps commands to pipeline actions.
+
+## Pipeline state machine
+The pipeline is a long-lived goroutine managed by the daemon. It exposes a small interface and uses channels to coordinate actions and notifications.
+
+States (from `internal/pipeline/pipeline.go`):
+
+`idle -> recording -> transcribing -> processing -> injecting -> idle`
+
+Key transitions:
+- Toggle while idle: start recorder + transcriber, move to recording/transcribing.
+- Inject action: stop recorder, finalize transcription, optional LLM processing, inject text.
+- Cancel: stop current action and return to idle.
+
+Key interface (simplified):
+- `Pipeline.Run()` starts the pipeline loop.
+- `Pipeline.Stop()` stops the current run.
+- `Pipeline.GetActionCh()` receives actions (toggle inject).
+- `Pipeline.GetNotifyCh()` emits user-facing events.
+- `Pipeline.GetErrorCh()` emits errors for the daemon to handle.
+
+## Recording
+`internal/recording/recording.go` defines `Recorder` with `Start/Stop/IsRecording`.
+The default implementation wraps `pw-record` and emits `AudioFrame` chunks on a buffered channel.
+
+## Transcription
+`internal/transcriber/transcriber.go` defines the core interfaces:
+
+- `Transcriber`: lifecycle + `GetFinalTranscription()`.
+- `BatchAdapter`: `Transcribe(audio, opts)` for full-file transcription.
+- `StreamingAdapter`: `Start/SendChunk/Results/Finalize/Close` for realtime.
+
+`NewTranscriber()` selects between `SimpleTranscriber` (batch) and `StreamingTranscriber` (streaming) based on provider model metadata. Streaming adapters deliver incremental `TranscriptionResult` events and a final transcript on stop/finalize.
+
+## LLM post-processing
+`internal/llm/llm.go` defines an `Adapter` interface with `Process(text, config)`.
+Adapters (OpenAI, Groq) use a shared prompt builder in `internal/llm/prompt.go`.
+The pipeline invokes LLM processing only if enabled in config.
+
+## Injection
+`internal/injection/injection.go` defines `Injector` and an ordered list of backends.
+`internal/injection/backend.go` defines the `Backend` interface (`Name/Available/Inject`).
+Backends include:
+- `wtype` (Wayland typing)
+- `ydotool` (uinput typing)
+- `wl-clipboard` fallback
+
+The injector tries backends in order and falls back to clipboard when typing fails.
+
+## Provider registry and adapter selection
+Providers register themselves via `internal/provider/provider.go` and return model catalogs.
+Each `Model` includes:
+- `AdapterType` (which adapter to use)
+- `Endpoint` and optional `StreamingEndpoint`
+- `SupportedLanguages` and model capabilities
+
+`internal/provider/names.go` holds adapter constants and provider names. `internal/provider/model.go` implements language compatibility checks. `internal/provider/provider.go` exposes helpers like `GetModel`, `ModelsForLanguage`, and `ValidateModelLanguage`.
+
+## Language compatibility
+`internal/language/language.go` defines the canonical language list and provider-specific formatting (ex: Deepgram locale mapping). Model-level language filters enforce compatibility at config time and runtime.
+
+## Config lifecycle and hot reload
+`internal/config/load.go` loads config, applies defaults, and resolves env-based API keys. `internal/config/validate.go` enforces model/language compatibility and provider requirements. `internal/config/convert.go` converts config into runtime structs for the pipeline.
+
+`internal/config/manager.go` watches `~/.config/hyprvoice/config.toml` and triggers reloads with a debounce. The daemon wires `onConfigReload` to stop any running pipeline, refresh notifiers, and apply new settings without a restart.
+
+## Notifications and errors
+The pipeline emits notification events and errors via channels. The daemon consumes them and uses `internal/notify` to display status changes to the user.
+
+## Extending the system
+Common extension points:
+
+- Add a new transcription provider:
+  - Define a provider catalog in `internal/provider/`.
+  - Implement a `BatchAdapter` or `StreamingAdapter` in `internal/transcriber/`.
+  - Add adapter constants in `internal/provider/names.go`.
+  - Update provider docs in `docs/providers.md`.
+  - Run `hyprvoice test-models` to verify the integration (see `docs/testing.md`).
+
+- Add a new injection backend:
+  - Implement `Backend` in `internal/injection/`.
+  - Register it in the injector order (config driven).
+
+- Add a new LLM adapter:
+  - Implement `Adapter` in `internal/llm/`.
+  - Wire it in `NewAdapter()` and expose config knobs.

+# Configuration Reference
+
+This document covers manual configuration of hyprvoice via the `config.toml` file. For most users, the interactive wizard is recommended:
+
+```bash
+hyprvoice onboarding
+```
+
+To adjust settings later:
+
+```bash
+hyprvoice configure
+```
+
+Configuration is stored in `~/.config/hyprvoice/config.toml` and changes are applied immediately without restarting the daemon.
+
+## Onboarding vs Configure
+
+- `hyprvoice onboarding`: guided first-time setup for provider keys, voice model, language/streaming, LLM post-processing, keywords, and notifications. Advanced settings stay at defaults.
+- `hyprvoice configure`: full TUI menu for all sections, including advanced recording, injection backends, timeouts, and notification messages.

+## Unified Provider System
+
+Hyprvoice uses a unified provider system where API keys are configured once and shared between transcription and LLM features:
+
+```toml
+# Configure API keys for providers you want to use
+[providers.openai]
+  api_key = "sk-..."           # Or set OPENAI_API_KEY env var
+
+[providers.groq]
+  api_key = "gsk_..."          # Or set GROQ_API_KEY env var
+
+[providers.mistral]
+  api_key = "..."              # Or set MISTRAL_API_KEY env var
+
+[providers.elevenlabs]
+  api_key = "..."              # Or set ELEVENLABS_API_KEY env var
+
+[providers.deepgram]
+  api_key = "..."              # Or set DEEPGRAM_API_KEY env var
+```
+
+**API key resolution order:**
+
+1. `[providers.X]` section in config
+2. Environment variable (`OPENAI_API_KEY`, `GROQ_API_KEY`, etc.)
+
+## Transcription Providers
+
+Hyprvoice supports multiple transcription backends. See [docs/providers.md](./providers.md) for detailed comparisons.
+
+### Cloud Providers
+
+### OpenAI Whisper API
+
+Cloud-based transcription using OpenAI's Whisper API:
+
+```toml
+[transcription]
+provider = "openai"
+model = "whisper-1"
+language = ""                   # Empty for auto-detect, or "en", "es", "fr", etc.
+```
+
+**Features:**
+
+- High-quality transcription
+- Supports 50+ languages
+- Auto-detection or specify language for better accuracy
+
+### Groq Whisper API (Transcription)
+
+Fast cloud-based transcription using Groq's Whisper API:
+
+```toml
+[transcription]
+provider = "groq-transcription"
+model = "whisper-large-v3"      # Or "whisper-large-v3-turbo" for faster processing
+language = ""                   # Empty for auto-detect, or "en", "es", "fr", etc.
+```
+
+**Features:**
+
+- Ultra-fast transcription (significantly faster than OpenAI)
+- Same Whisper model quality
+- Supports 50+ languages
+- Free tier available with generous limits
+
+### Mistral Voxtral
+
+Transcription using Mistral's Voxtral API, excellent for European languages:
+
+Note: Mistral's API supports streaming responses, but it is not real-time audio streaming. Hyprvoice treats Voxtral as batch-only.
+
+```toml
+[transcription]
+provider = "mistral-transcription"
+model = "voxtral-mini-latest"
+language = ""                   # Empty for auto-detect
+```
+
+### ElevenLabs Scribe
+
+Transcription using ElevenLabs' Scribe API with 57+ language support:
+
+```toml
+[transcription]
+provider = "elevenlabs"
+model = "scribe_v1"             # Or "scribe_v2" for lower latency (batch)
+language = ""                   # Empty for auto-detect
+```
+
+**Features:**
+
+- 57+ languages supported
+- Both batch and streaming models available
+- Ultra-low latency streaming options
+
+### Deepgram Nova
+
+Fast streaming transcription using Deepgram's Nova models:
+
+```toml
+[providers.deepgram]
+  api_key = "..."               # Or set DEEPGRAM_API_KEY env var
+
+[transcription]
+provider = "deepgram"
+model = "nova-3"                # Or "nova-2" for different language support
+language = ""                   # Empty for auto-detect
+```
+
+**Features:**
+
+- Flux: streaming-only, English with turn detection
+- Nova-3: 42 languages, best accuracy (batch+streaming)
+- Nova-2: 33 languages, faster with filler word detection (batch+streaming)
+- Excellent for real-time transcription and live captions
+
+### Local Transcription (whisper-cpp)
+
+Run Whisper models locally on your machine. No API keys, no network latency, complete privacy.
+
+**Prerequisites:**
+
+1. Install whisper-cli: https://github.com/ggerganov/whisper.cpp
+2. Download a model: `hyprvoice model download base.en`
+
+```toml
+[transcription]
+provider = "whisper-cpp"
+model = "base.en"               # English-only model (fastest)
+language = ""                   # Empty for auto-detect (use "en" for English-only models)
+threads = 0                     # 0 = auto (uses NumCPU - 1)
+```
+
+**Available models:**
+
+| Model | Size | Languages | Best For |
+|-------|------|-----------|----------|
+| `tiny.en` | 75MB | English only | Quick tests, low-power devices |
+| `base.en` | 142MB | English only | Daily use, good balance |
+| `small.en` | 466MB | English only | Better accuracy |
+| `medium.en` | 1.5GB | English only | Best English accuracy |
+| `tiny` | 75MB | 57 languages | Quick multilingual |
+| `base` | 142MB | 57 languages | Daily multilingual use |
+| `small` | 466MB | 57 languages | Better multilingual |
+| `medium` | 1.5GB | 57 languages | Great accuracy |
+| `large-v1` | 2.9GB | 57 languages | Best accuracy |
+| `large-v2` | 2.9GB | 57 languages | Best accuracy |
+| `large-v3` | 3GB | 57 languages | Best accuracy |
+| `large-v3-turbo` | 1.6GB | 57 languages | Faster large-v3 |
+
+**Threads configuration:**
+
+- `threads = 0` (default): auto-detects, uses NumCPU - 1 to leave one core free
+- `threads = 4`: explicitly use 4 threads
+- Higher thread count = faster transcription but more CPU usage
+
+### Streaming Transcription
+
+For real-time transcription, use streaming models:
+
+```toml
+# ElevenLabs streaming (realtime only)
+[transcription]
+provider = "elevenlabs"
+model = "scribe_v2_realtime"
+streaming = true
+
+# Deepgram streaming (all models support streaming)
+[transcription]
+provider = "deepgram"
+model = "nova-3"
+
+# OpenAI Realtime
+[transcription]
+provider = "openai"
+model = "gpt-4o-realtime-preview"
+```
+
+**Streaming models:**
+
+| Provider | Model | Latency | Languages |
+|----------|-------|---------|-----------|
+| ElevenLabs | `scribe_v2_realtime` | <150ms | 57+ |
+| Deepgram | `flux-general-en` | Very Low | en |
+| Deepgram | `nova-3` | Low | 42 |
+| Deepgram | `nova-2` | Very Low | 33 |
+| OpenAI | `gpt-4o-realtime-preview` | Low | 57 |
+
+### Language Configuration
+
+Language is configured per transcription model in the `[transcription]` section:
+
+```toml
+[transcription]
+provider = "openai"
+model = "whisper-1"
+language = ""                   # Empty for auto-detect (recommended)
+# language = "en"               # English
+# language = "es"               # Spanish
+# language = "fr"               # French
+```
+
+When using `hyprvoice configure`, you select the language after choosing the model. Only languages supported by the selected model are shown.
+
+**Recommendations:**
+
+- Use auto-detect (`language = ""`) for most cases - it works well
+- Specify a language if you always speak the same language (slight accuracy boost)
+- English-only models (e.g., `base.en`) only support `language = "en"` or auto-detect
+
+### Supported Languages
+
+Hyprvoice supports 57 languages:
+
+Afrikaans (af), Arabic (ar), Armenian (hy), Azerbaijani (az), Belarusian (be), Bosnian (bs), Bulgarian (bg), Catalan (ca), Chinese (zh), Croatian (hr), Czech (cs), Danish (da), Dutch (nl), English (en), Estonian (et), Finnish (fi), French (fr), Galician (gl), German (de), Greek (el), Hebrew (he), Hindi (hi), Hungarian (hu), Icelandic (is), Indonesian (id), Italian (it), Japanese (ja), Kannada (kn), Kazakh (kk), Korean (ko), Latvian (lv), Lithuanian (lt), Macedonian (mk), Malay (ms), Marathi (mr), Maori (mi), Nepali (ne), Norwegian (no), Persian (fa), Polish (pl), Portuguese (pt), Romanian (ro), Russian (ru), Serbian (sr), Slovak (sk), Slovenian (sl), Spanish (es), Swahili (sw), Swedish (sv), Tagalog (tl), Tamil (ta), Thai (th), Turkish (tr), Ukrainian (uk), Urdu (ur), Vietnamese (vi), Welsh (cy)
+
+### Language-Model Compatibility
+
+Some models only support English. When configuring via `hyprvoice configure`, only supported languages are shown for selection.
+
+**English-only models:**
+
+| Provider | Model |
+|----------|-------|
+| whisper-cpp | `tiny.en`, `base.en`, `small.en`, `medium.en` |
+
+**Deepgram models** support fewer languages than the full 57 - see [providers.md](./providers.md#deepgram-language-support).
+
+**Validation behavior:**
+
+1. **At config time (TUI):** Only languages supported by the selected model are shown
+2. **At runtime:** If config was manually edited to an invalid combination, hyprvoice logs a warning, sends a desktop notification, and falls back to auto-detect
+
+```toml
+# This combination will be rejected at validation:
+[transcription]
+provider = "whisper-cpp"
+model = "base.en"                 # English only!
+language = "es"                         # Error: model does not support Spanish
+```
+
+## Model Management
+
+Manage local whisper models with CLI commands:
+
+### List Models
+
+```bash
+# List all models
+hyprvoice model list
+
+# Filter by provider
+hyprvoice model list --provider whisper-cpp
+
+# Filter by type
+hyprvoice model list --type transcription
+```
+
+Shows installed status `[x]` for local models and model details.
+
+### Download Models
+
+```bash
+# Download a whisper model
+hyprvoice model download base.en
+
+# Download with progress
+hyprvoice model download large-v3
+```
+
+Cloud models (OpenAI, Groq, etc.) don't require download - this is for local models only.
+
+### Remove Models
+
+```bash
+# Remove a downloaded model
+hyprvoice model remove base.en
+```
+
+## LLM Post-Processing
+
+LLM post-processing is **enabled by default** and significantly improves transcription quality. After transcription, the text is processed by an LLM to:
+
+- Remove stutters and repeated words ("I I I want" → "I want")
+- Add proper punctuation
+- Fix grammar errors
+- Remove filler words ("um", "uh", "like", "you know", etc.)
+
+### Basic Configuration
+
+```toml
+[llm]
+  enabled = true               # Disable with false if you want raw transcriptions
+  provider = "openai"          # "openai" or "groq"
+  model = "gpt-4o-mini"        # OpenAI: "gpt-4o-mini", Groq: "llama-3.3-70b-versatile"
+```
+
+### Post-Processing Options
+
+All options are enabled by default. Disable specific ones as needed:
+
+```toml
+[llm.post_processing]
+  remove_stutters = true       # "I I I want" → "I want"
+  add_punctuation = true       # Adds periods, commas, etc.
+  fix_grammar = true           # Fixes grammatical errors
+  remove_filler_words = true   # Removes "um", "uh", "like", "you know"
+```
+
+### Custom Prompts
+
+Add custom instructions for specific use cases:
+
+```toml
+[llm.custom_prompt]
+  enabled = true
+  prompt = "Format as bullet points"
+```
+
+**Use cases for custom prompts:**
+
+- "Format as bullet points" - for note-taking
+- "Keep technical terms exactly as spoken" - for programming dictation
+- "Use formal language" - for professional documents
+- "Translate to Spanish" - for translation workflows
+
+### LLM Provider Recommendations
+
+| Provider | Model                   | Best For                            |
+| -------- | ----------------------- | ----------------------------------- |
+| OpenAI   | gpt-4o-mini             | Best quality/cost balance (default) |
+| Groq     | llama-3.3-70b-versatile | Fastest processing, free tier       |
+
+## Keywords
+
+Keywords help both transcription and LLM understand domain-specific terms, names, and technical vocabulary:
+
+```toml
+keywords = ["Hyprland", "Wayland", "PipeWire", "Claude", "TypeScript"]
+```
+
+**How keywords work:**
+
+- **Transcription**: Passed as provider-specific hints (prompt/keyterms/keywords) when supported to improve recognition
+- **LLM**: Included in the system prompt to ensure correct spelling
+
+**When to use keywords:**
+
+- Names of people, companies, or products
+- Technical terminology specific to your field
+- Acronyms or abbreviations
+- Words commonly misheard by speech-to-text
+
+## Recording Configuration
+
+Audio capture settings:
+
+```toml
+[recording]
+sample_rate = 16000        # Audio sample rate in Hz (16000 recommended for speech)
+channels = 1               # Number of audio channels (1 = mono, 2 = stereo)
+format = "s16"             # Audio format (s16 = 16-bit signed integers)
+buffer_size = 8192         # Internal buffer size in bytes (larger = less CPU, more latency)
+device = ""                # PipeWire device name (empty = default microphone)
+channel_buffer_size = 30   # Audio frame buffer size (frames to buffer)
+timeout = "5m"             # Maximum recording duration (e.g., "30s", "2m", "5m")
+```
+
+### Recording Timeout
+
+- Prevents accidental long recordings that could consume resources
+- Default: 5 minutes (`"5m"`)
+- Format: Go duration strings like `"30s"`, `"2m"`, `"10m"`
+- Recording automatically stops when timeout is reached
+
+## Text Injection
+
+Configurable text injection with multiple backends:
+
+```toml
+[injection]
+backends = ["ydotool", "wtype", "clipboard"]  # Ordered fallback chain
+ydotool_timeout = "5s"
+wtype_timeout = "5s"
+clipboard_timeout = "3s"
+```
+
+### Injection Backends
+
+- **`ydotool`**: Uses ydotool (requires `ydotoold` daemon for ydotool v1.0.0+). Most compatible with Chromium/Electron apps.
+- **`wtype`**: Uses wtype for Wayland. May have issues with some Chromium-based apps (known upstream bug).
+- **`clipboard`**: Copies text to clipboard only. Most reliable, but requires manual paste.
+
+### Fallback Chain
+
+Backends are tried in order. The first successful one wins. Example configurations:
+
+```toml
+# Clipboard only (safest, always works)
+backends = ["clipboard"]
+
+# wtype with clipboard fallback
+backends = ["wtype", "clipboard"]
+
+# Full fallback chain (default) - best compatibility
+backends = ["ydotool", "wtype", "clipboard"]
+
+# ydotool only (if you have it set up)
+backends = ["ydotool"]
+```
+
+### ydotool Setup
+
+ydotool requires the `ydotoold` daemon running (for ydotool v1.0.0+) and access to `/dev/uinput`:
+
+```bash
+# Start ydotool daemon (systemd)
+systemctl --user enable --now ydotool
+
+# Or add user to input group
+sudo usermod -aG input $USER
+# Then logout/login
+
+# For Hyprland, add to config to set correct keyboard layout:
+# device:ydotoold-virtual-device {
+#     kb_layout = us
+# }
+```
+
+## Notifications
+
+Desktop notification settings:
+
+```toml
+[notifications]
+enabled = true             # Enable/disable notifications
+type = "desktop"           # "desktop", "log", or "none"
+```
+
+### Notification Types
+
+- **`desktop`**: Use notify-send for desktop notifications
+- **`log`**: Log messages to console only
+- **`none`**: Disable all notifications
+
+### Custom Notification Messages
+
+You can customize notification text via the `[notifications.messages]` section:
+
+```toml
+[notifications.messages]
+  [notifications.messages.recording_started]
+    title = "Hyprvoice"
+    body = "Recording Started"
+  [notifications.messages.transcribing]
+    title = "Hyprvoice"
+    body = "Recording Ended... Transcribing"
+  [notifications.messages.llm_processing]
+    title = "Hyprvoice"
+    body = "Processing..."
+  [notifications.messages.config_reloaded]
+    title = "Hyprvoice"
+    body = "Config Reloaded"
+  [notifications.messages.operation_cancelled]
+    title = "Hyprvoice"
+    body = "Operation Cancelled"
+  [notifications.messages.recording_aborted]
+    body = "Recording Aborted"
+  [notifications.messages.injection_aborted]
+    body = "Injection Aborted"
+```
+
+**Emoji-only example** (for minimal pill-style notifications):
+
+```toml
+[notifications.messages.recording_started]
+  title = ""
+  body = "🎙️"
+```
+

+
+## Legacy Configs
+
+Older config formats are no longer supported. If your config uses any of these fields, rerun onboarding to regenerate a supported config:
+
+- `transcription.api_key`
+- `injection.mode`
+- `general.language`
+- `transcription.provider = "groq-translation"`
+
+Run `hyprvoice onboarding` to generate a new config, then `hyprvoice configure` for advanced settings.
+
+## Configuration Hot-Reloading
+
+The daemon automatically watches the config file for changes and applies them immediately:
+
+- **Notification settings**: Applied instantly
+- **Injection settings**: Applied to current and future operations
+- **Recording/Transcription/LLM settings**: Applied to new recording sessions
+- **Invalid configs**: Rejected with error notification, daemon continues with previous config

+2. Daemon receives the command and owns lifecycle and state transitions.
+3. Pipeline runs: recording -> transcribing -> processing -> injecting.
+4. Notifications reflect state changes and errors.
+
+State machine: idle -> recording -> transcribing -> processing -> injecting -> idle
+
+## Key packages
+- internal/bus: unix socket IPC, pid file, and client helpers
+- internal/daemon: command handling, lifecycle, pipeline ownership
+- internal/config: load/save/validate config and hot reload
+- internal/pipeline: state machine coordinating recording/transcriber/llm/injection
+- internal/recording: PipeWire audio capture
+- internal/transcriber: batch and streaming provider adapters
+- internal/llm: post-processing adapters and prompts
+- internal/injection: wtype/ydotool/clipboard injection

+
+## IPC protocol (daemon control)
+- Socket: ~/.cache/hyprvoice/control.sock
+- Commands: t=toggle, c=cancel, s=status, v=version, q=quit
+
+## Data and config locations
+- Config: ~/.config/hyprvoice/config.toml
+- Models: ~/.local/share/hyprvoice/models/whisper/

+# Integration Testing
+
+This doc covers `test-models`, the e2e test command for validating provider APIs work correctly.
+
+## When to Run
+
+Run `test-models` when:
+- adding a new provider or model
+- updating provider adapters
+- debugging API connectivity issues
+- verifying API keys are valid
+- before releases (CI runs this automatically)
+
+## Quick Start
+
+```bash
+# test all configured providers (requires API keys)
+hyprvoice test-models
+
+# output results to json
+hyprvoice test-models --output results.json
+```
+
+## What It Tests
+
+The command validates:
+1. **Transcription providers**: sends a sample audio file through each model and verifies a transcription is returned
+2. **LLM providers**: sends a test phrase through each model and verifies post-processing works
+
+For each model, it reports:
+- pass: API responded with valid output
+- fail: API error or timeout
+- skip: missing API key or dependency (e.g. whisper-cli not installed)
+
+## API Keys
+
+Keys are resolved from config or environment variables:
+- `OPENAI_API_KEY`
+- `GROQ_API_KEY`
+- `DEEPGRAM_API_KEY`
+- `ELEVENLABS_API_KEY`
+- `MISTRAL_API_KEY`
+
+Models without a valid key are skipped (not failed).
+
+## Options
+
+| Flag | Default | Description |
+|------|---------|-------------|
+| `--audio` | (downloaded sample) | custom WAV file to use |
+| `--record-seconds` | 0 | record mic instead of using a file (e.g. `5s`) |
+| `--timeout` | 45s | per-model timeout |
+| `--output` | (none) | write JSON report to file |
+| `--realtime` | true | pace streaming chunks in real time |
+| `--both-modes` | true | test batch+streaming models in both modes |
+| `--local-model` | (smallest) | whisper-cpp model to test |
+| `--download-local` | false | download local model if missing |
+| `--language` | en | language code for tests |
+| `--keywords` | Hyprvoice,transcription,dictation | keywords for provider hints |
+| `--no-keywords` | false | skip keyword hints |
+| `--no-language` | false | use auto-detect instead of explicit language |
+
+## Examples
+
+```bash
+# basic run - uses downloaded sample audio
+hyprvoice test-models
+
+# use your own audio file
+hyprvoice test-models --audio ~/voice-sample.wav
+
+# record 5 seconds from mic
+hyprvoice test-models --record-seconds 5s
+
+# longer timeout for slow connections
+hyprvoice test-models --timeout 90s
+
+# test local whisper-cpp with specific model
+hyprvoice test-models --local-model base.en --download-local
+
+# json report for CI
+hyprvoice test-models --output test-results.json
+```
+
+## Output
+
+Terminal output shows pass/fail/skip for each model:
+
+```
+test-models: total=25 pass=18 fail=2 skip=5
+audio: /home/user/.cache/hyprvoice/testaudio.wav
+pass openai/whisper-1 batch 1234ms output="She had your dark suit..."
+pass openai/gpt-4o-transcribe batch 2156ms output="She had your dark suit..."
+pass groq-transcription/whisper-large-v3 batch 456ms output="She had your dark suit..."
+skip deepgram/nova-3 batch error=missing api key
+fail mistral-transcription/voxtral-mini-latest batch 45000ms error=context deadline exceeded
+pass openai/gpt-4o-mini llm 892ms output="I want to test Hyprvoice..."
+```
+
+JSON report (`--output`) includes full details:
+
+```json
+{
+  "started_at": "2024-01-15T10:30:00Z",
+  "audio_src": "/home/user/.cache/hyprvoice/testaudio.wav",
+  "results": [
+    {
+      "provider": "openai",
+      "model": "whisper-1",
+      "type": "transcription",
+      "mode": "batch",
+      "local": false,
+      "status": "pass",
+      "duration_ms": 1234,
+      "output": "She had your dark suit...",
+      "output_chars": 45
+    }
+  ],
+  "pass_count": 18,
+  "fail_count": 2,
+  "skip_count": 5,
+  "total_count": 25
+}
+```
+
+## CI Integration
+
+The repo includes a GitHub Actions workflow (`.github/workflows/e2e.yml`) that runs `test-models` on demand:
+
+```yaml
+# triggered manually via workflow_dispatch
+./hyprvoice test-models \
+  --timeout=60s \
+  --output=test-models-report.json
+```
+
+Secrets required in repo settings:
+- `OPENAI_API_KEY`
+- `GROQ_API_KEY`
+- `DEEPGRAM_API_KEY`
+- `ELEVENLABS_API_KEY`
+- `MISTRAL_API_KEY`
+
+## Adding a New Provider
+
+When adding a new provider:
+
+1. implement the adapter in `internal/transcriber/` or `internal/llm/`
+2. register models in `internal/provider/`
+3. add env var mapping if needed
+4. run `test-models` to verify:
+   ```bash
+   hyprvoice test-models --output before-merge.json
+   ```
+5. add the API key to CI secrets
+
+## Local Model Testing
+
+whisper-cpp models require:
+- `whisper-cli` binary installed
+- model downloaded (`hyprvoice model download <model>`)
+
+Use `--download-local` to auto-download during test:
+
+```bash
+hyprvoice test-models --local-model tiny.en --download-local
+```
+
+Only the smallest local model is tested by default to save time. If it works, larger models should work too.
+
+## Troubleshooting
+
+**All models skipped**: check API keys are set in env or config
+
+**Timeouts**: increase `--timeout`, check network connectivity
+
+**whisper-cpp skipped**: install `whisper-cli` and download a model
+
+**Streaming failures**: some providers have separate streaming endpoints - check provider docs

-# Backend explanations:
-# - "ydotool": Uses ydotool (requires ydotoold daemon running for ydotool v1.0.0+). Most compatible with Chromium/Electron apps.
-# - "wtype": Uses wtype for Wayland. May have issues with some Chromium-based apps.
-# - "clipboard": Copies text to clipboard only (most reliable, but requires manual paste).
-#
-# The backends are tried in order. First successful one wins.
-# Example configurations:
-#   backends = ["clipboard"]                      # Clipboard only (safest)
-#   backends = ["wtype", "clipboard"]             # wtype with clipboard fallback
-#   backends = ["ydotool", "wtype", "clipboard"]  # Full fallback chain (default)
-#
-# Provider explanations:
-# - "openai": OpenAI Whisper API (cloud-based, requires OPENAI_API_KEY)
-# - "groq-transcription": Groq Whisper API for transcription (fast, requires GROQ_API_KEY)
-#     Models: whisper-large-v3 or whisper-large-v3-turbo
-# - "groq-translation": Groq Whisper API for translation to English (always outputs English text)
-#     Models: whisper-large-v3 only (turbo not supported for translation)
-# - "mistral-transcription": Mistral Voxtral API (excellent for European languages, requires MISTRAL_API_KEY)
-#     Models: voxtral-mini-latest or voxtral-mini-2507
-# - "elevenlabs": ElevenLabs Scribe API (excellent accuracy, 99 languages, requires ELEVENLABS_API_KEY)
-#     Models: scribe_v1 (99 languages, best accuracy) or scribe_v2 (90 languages, real-time)
-#
-# Language codes: Use empty string ("") for automatic detection, or specific codes like:
-# "en" (English), "it" (Italian), "es" (Spanish), "fr" (French), "de" (German), etc.
-# For groq-translation, the language field hints at the source audio language for better accuracy.
