+# Contributing to Voicebox
+
+Thank you for your interest in contributing to Voicebox! This document provides guidelines and instructions for contributing.
+
+## Code of Conduct
+
+- Be respectful and inclusive
+- Welcome newcomers and help them learn
+- Focus on constructive feedback
+- Respect different viewpoints and experiences
+
+## Getting Started
+
+### Prerequisites
+
+- **[Bun](https://bun.sh)** - Fast JavaScript runtime and package manager
+  ```bash
+  curl -fsSL https://bun.sh/install | bash
+  ```
+
+- **[Python 3.11+](https://python.org)** - For backend development
+  ```bash
+  python --version  # Should be 3.11 or higher
+  ```
+
+- **[Rust](https://rustup.rs)** - For Tauri desktop app (installed automatically by Tauri CLI)
+  ```bash
+  rustc --version  # Check if installed
+  ```
+
+- **Git** - Version control
+
+### Development Setup
+
+**Using the Makefile (recommended for macOS/Linux):** Run `make setup` to install all dependencies, then `make dev` to start development servers. See `make help` for all available commands.
+
+**Manual setup (required for Windows):**
+
+1. **Fork and clone the repository**
+   ```bash
+   git clone https://github.com/YOUR_USERNAME/voicebox.git
+   cd voicebox
+   ```
+
+2. **Install JavaScript dependencies**
+   ```bash
+   bun install
+   ```
+   This installs dependencies for:
+   - `app/` - Shared React frontend
+   - `tauri/` - Tauri desktop wrapper
+   - `web/` - Web deployment wrapper
+
+3. **Set up Python backend**
+   ```bash
+   cd backend
+   
+   # Create virtual environment
+   python -m venv venv
+   
+   # Activate virtual environment
+   source venv/bin/activate  # On macOS/Linux
+   # or
+   venv\Scripts\activate  # On Windows
+   
+   # Install Python dependencies
+   pip install -r requirements.txt
+   
+   # Install MLX dependencies (Apple Silicon only - for faster inference)
+   # On Apple Silicon, this enables native Metal acceleration
+   if [[ $(uname -m) == "arm64" ]]; then
+     pip install -r requirements-mlx.txt
+   fi
+   
+   # Install Qwen3-TTS (required for voice synthesis)
+   pip install git+https://github.com/QwenLM/Qwen3-TTS.git
+   ```
+
+4. **Start development servers**
+
+   Development requires two terminals: one for the Python backend, one for the Tauri app.
+
+   **Terminal 1: Backend server** (start this first)
+   ```bash
+   cd backend
+   source venv/bin/activate  # Activate venv if not already active
+   bun run dev:server
+   # Or manually: uvicorn main:app --reload --port 17493
+   ```
+   Backend will be available at `http://localhost:17493`
+
+   **Terminal 2: Desktop app**
+   ```bash
+   bun run dev
+   ```
+   This will:
+   - Create a placeholder sidecar binary (for Tauri compilation)
+   - Start Vite dev server on port 5173
+   - Launch Tauri window pointing to localhost:5173
+   - Connect to the Python server you started in Terminal 1
+   - Enable hot reload
+
+   > **Note:** In dev mode, the app connects to your manually-started Python server.
+   > The bundled server binary is only used in production builds.
+
+   **Optional: Web app**
+   ```bash
+   bun run dev:web
+   ```
+   Web app will be available at `http://localhost:5174`
+
+### Model Downloads
+
+Models are automatically downloaded from HuggingFace Hub on first use:
+- **Whisper** (transcription): Auto-downloads on first transcription
+- **Qwen3-TTS** (voice cloning): Auto-downloads on first generation (~2-4GB)
+
+First-time usage will be slower due to model downloads, but subsequent runs will use cached models.
+
+### Building
+
+**Build everything (recommended):**
+```bash
+bun run build
+```
+This automatically:
+1. Builds the Python server binary (`./scripts/build-server.sh`)
+2. Builds the Tauri desktop app (`cd tauri && bun run tauri build`)
+
+Creates platform-specific installers (`.dmg`, `.msi`, `.AppImage`) in `tauri/src-tauri/target/release/bundle/`.
+
+**Note:** The build process detects your platform and includes the appropriate backend (MLX for Apple Silicon, PyTorch for others).
+
+**Build server binary only:**
+```bash
+bun run build:server
+# or
+./scripts/build-server.sh
+```
+Creates platform-specific binary in `tauri/src-tauri/binaries/`
+
+**Building with local Qwen3-TTS development version:**
+
+If you're actively developing or modifying the Qwen3-TTS library, set the `QWEN_TTS_PATH` environment variable to point to your local clone:
+
+```bash
+export QWEN_TTS_PATH=~/path/to/your/Qwen3-TTS
+bun run build:server
+```
+
+This makes PyInstaller use your local qwen-tts version instead of the pip-installed package. Useful when testing changes to the TTS library before they're published to PyPI or when using an editable install (`pip install -e`).
+
+**Build web app:**
+```bash
+cd web
+bun run build
+```
+Output in `web/dist/`
+
+### Generate OpenAPI Client
+
+After starting the backend server:
+```bash
+./scripts/generate-api.sh
+```
+This downloads the OpenAPI schema and generates the TypeScript client in `app/src/lib/api/`
+
+### Convert Assets to Web Formats
+
+To optimize images and videos for the web, run:
+```bash
+bun run convert:assets
+```
+
+This script:
+- Converts PNG → WebP (better compression, same quality)
+- Converts MOV → WebM (VP9 codec, smaller file size)
+- Processes files in `landing/public/` and `docs/public/`
+- **Deletes original files** after successful conversion
+
+**Requirements:** Install `webp` and `ffmpeg`:
+```bash
+brew install webp ffmpeg
+```
+
+> **Note:** Run this before committing new images or videos to keep the repository size small.
+
+## Development Workflow
+
+### 1. Create a Branch

+export function ProfileCard({ profile }: { profile: Profile }) {
+  return <div>{profile.name}</div>;
+}
+
+// Avoid
+export const ProfileCard = (props) => { ... }
+```
+
+### Python
+
+- Follow PEP 8 style guide
+- Use type hints
+- Use async/await for I/O operations
+- Format with Black (if configured)
+
+```python

+## What is Voicebox?
+
+Voicebox is a **local-first voice cloning studio** with DAW-like features for professional voice synthesis. Think of it as the **Ollama for voice** — download models, clone voices, and generate speech entirely on your machine.
+
+Unlike cloud services that lock your voice data behind subscriptions, Voicebox gives you:
+
+- **Complete privacy** — models and voice data stay on your machine
+- **Professional tools** — multi-track timeline editor, audio trimming, conversation mixing
+- **Model flexibility** — currently powered by Qwen3-TTS, with support for XTTS, Bark, and other models coming soon
+- **API-first** — use the desktop app or integrate voice synthesis into your own projects
+- **Native performance** — built with Tauri (Rust), not Electron
+
+Download a voice model, clone any voice from a few seconds of audio, and compose multi-voice projects with studio-grade editing tools. No Python install required, no cloud dependency, no limits.
 
 ---
 
-## Vision
+## Download
 
-Qwen3-TTS is a breakthrough model from Alibaba that achieves near-perfect voice cloning. The existing implementations (Voice-Clone-Studio, mimic, etc.) are either feature-rich but architecturally messy, or well-structured but limited in scope.
+Voicebox is available now for macOS and Windows.
 
-voicebox aims to build the definitive Qwen3-TTS application by combining the best patterns from existing projects while avoiding their architectural mistakes.

+> **Linux builds coming soon** — Currently blocked by GitHub runner disk space limitations.
 
-1. **Clean architecture from day one** - No monolithic files, proper separation of concerns
-2. **Desktop-first experience** - Native feel via Tauri, not a web app in disguise
-3. **Production code quality** - Type safety, modularity, maintainability
-4. **Performance and UX** - Smart caching, async operations, responsive UI
-5. **Extensible design** - Easy to add new models, effects, and features
-6. **Flexible deployment** - Run backend locally or connect to remote GPU machine with one click

+- **Multi-sample support** — combine multiple samples for higher quality cloning
+- **Organize** with descriptions and language tags
 
-### Local Mode (Default)
-- Backend runs locally alongside the Tauri app
-- Best for users with GPU on their primary machine
+### Speech Generation
 
-### Remote Mode (One-Click Setup)
-- **Use case:** Your laptop doesn't have a GPU, but your desktop does
-- **Server:** Run voicebox on GPU machine, click "Start Server"
-  - Starts FastAPI backend on local network
-  - Shows connection URL (e.g., `http://192.168.1.100:8000`)
-- **Client:** Run voicebox on laptop, enter server URL
-  - Connects to remote backend
-  - Full UI functionality, inference happens on GPU machine
-- **Security:** Local network only for now (no internet exposure)
+- **Text-to-speech** with any cloned voice
+- **Batch generation** for long-form content

+- **One-click server** — Turn any machine into a Voicebox server
+
+---
+
+## API
+
+Voicebox exposes a full REST API, so you can integrate voice synthesis into your own apps.
+
+```bash
+# Generate speech
+curl -X POST http://localhost:8000/generate \
+  -H "Content-Type: application/json" \
+  -d '{"text": "Hello world", "profile_id": "abc123", "language": "en"}'
+
+# List voice profiles
+curl http://localhost:8000/profiles
+
+# Create a profile
+curl -X POST http://localhost:8000/profiles \
+  -H "Content-Type: application/json" \
+  -d '{"name": "My Voice", "language": "en"}'
 ```

-**Key architectural decisions:**
-- **Shared frontend** - `app/` contains all React code, used by both desktop and web
-- **Thin wrappers** - `tauri/` and `web/` just configure build tools and entry points
-- **Bundled backend** - Python server packaged as sidecar binary with PyInstaller
-- **Type-safe API** - OpenAPI schema generated from FastAPI, TypeScript client auto-generated
+---
 
-See [TAURI_PLAN.md](./docs/TAURI_PLAN.md) for detailed bundling strategy.

-## Development Roadmap
-
-### Week 1: Foundation
-- Project structure setup
-- Backend skeleton (FastAPI + SQLite)
-- OpenAPI schema generation
-- Frontend skeleton (Tauri + React)
-- TypeScript client generation from OpenAPI
-- React Query setup
-- Basic voice profile CRUD
-- Server mode implementation
-- Client connection UI
-
-### Week 2: Core Features
-- TTS integration
-- Voice cloning pipeline
-- Voice prompt caching
-- Generation history
-
-### Week 3: UX Polish
-- Audio playback and preview
-- Profile management UI
-- History search and filters
-- Error handling and validation
-
-### Week 4: Advanced Features
-- Multi-reference combination
-- Batch generation
-- Audio normalization
-- M3GAN effect
-
-### Week 5+: Studio Features
-- Timeline editor
-- Word-level timestamps
-- Project system
-- Export pipeline
-
-## Technical Decisions
-
-### Why Tauri over Electron?
-- Smaller bundle size (Rust vs. Node.js)
-- Better performance (native vs. V8)
-- Lower memory usage
-- Rust for system-level operations
-
-### Why FastAPI over Flask?
-- Native async/await support
-- Automatic OpenAPI schema generation
-- Pydantic validation built-in
-- Better performance
-
-### Why OpenAPI + React Query?
-- **Type safety end-to-end** - FastAPI generates OpenAPI schema, we generate TypeScript client
-- **No manual API code** - Client generated from `openapi.json` using openapi-typescript-codegen
-- **Automatic caching** - React Query handles request deduplication and background refetching
-- **Optimistic updates** - Update UI immediately, rollback on error
-- **DevX** - Full autocomplete and type checking for all API calls
-
-**Example workflow:**
-```bash
-# Backend generates OpenAPI schema
-python backend/main.py --openapi > openapi.json
-
-# Frontend generates TypeScript client
-bun run generate-client
-
-# Use type-safe hooks in React
-import { useQuery } from '@tanstack/react-query';
-import { ProfilesService } from '@/lib/api';
-
-const { data: profiles } = useQuery({
-  queryKey: ['profiles'],
-  queryFn: () => ProfilesService.listProfiles()
-});
-```
-
-### Why Bun over npm/yarn/pnpm?
-- **Speed** - 20-30x faster than npm for install operations
-- **Drop-in replacement** - Compatible with npm ecosystem, no migration needed
-- **Built-in tooling** - Bundler, test runner, and package manager in one
-- **Performance** - Faster script execution than Node.js
-- **Developer experience** - Better error messages, workspaces support
-
-### Why SQLite over file-based storage?
-- Full-text search
-- Transactions and integrity
-- Migrations via Alembic
-- Easy to backup/restore
-
-### Why React over Vue/Svelte?
-- Larger ecosystem
-- Better TypeScript support
-- Familiar to most developers
-- Mature tooling
-
-### Why bundle Python server with PyInstaller?
-- **No Python installation required** - Users don't need Python on their system
-- **Consistent environment** - Exact dependencies bundled, no version conflicts
-- **Single-click install** - One installer includes everything
-- **Tauri sidecar pattern** - Rust spawns/manages Python process lifecycle
-- **Platform-specific binaries** - PyInstaller creates native executables for each platform
-
-**Tradeoffs:**
-- Larger bundle size (~500MB with models vs ~50MB without backend)
-- Need separate build for each platform (macOS Intel/ARM, Windows, Linux)
-- First launch slower (model loading time)
-
-**Alternative considered:** Require users to install Python and run `pip install` - rejected for poor UX
-
-### Why no Docker initially?
-- Desktop app, not server deployment
-- Users install locally
-- Can add later for server mode
-
-## Performance Targets
-
-- **First generation:** < 10 seconds (cold start)
-- **Cached generation:** < 2 seconds (warm start)
-- **UI responsiveness:** 60 FPS at all times
-- **Memory usage:** < 4GB VRAM for small models
-- **Startup time:** < 3 seconds to UI
-- **Database queries:** < 100ms for history search
-
-## Quality Standards
-
-- **No files over 500 lines** (except auto-generated)
-- **Type hints on all Python functions**
-- **TypeScript strict mode enabled**
-- **OpenAPI client auto-generated from schema**
-- **ESLint + Prettier for frontend**
-- **Black + isort for backend**
-- **All user-facing errors have context**
-- **No global mutable state**
-- **React Query for all server state**
-
-## Project Status
-
-**Current phase:** Planning and analysis
-
-**Documentation:**
-- [ANALYSIS.md](./docs/ANALYSIS.md) - Comprehensive analysis of existing implementations
-- [TAURI_PLAN.md](./docs/TAURI_PLAN.md) - Tauri app architecture and Python server bundling strategy

-  python --version  # Should be 3.11 or higher
-  ```
-
-- **Rust** - For Tauri desktop app (installed automatically by Tauri CLI)
-  ```bash
-  rustc --version  # Check if installed
-  ```
-
-- **Node.js 18+** (optional) - Fallback if Bun is not available
-
-## Initial Setup
-
-### 1. Install Dependencies
-
-```bash
-# Install all workspace dependencies
-bun install
-```
-
-This will install dependencies for:
-- `app/` - Shared React frontend
-- `tauri/` - Tauri desktop wrapper
-- `web/` - Web deployment wrapper
-
-### 2. Setup Backend
-
-```bash
-cd backend
-
-# Create virtual environment
-python -m venv venv
-
-# Activate virtual environment
-source venv/bin/activate  # On macOS/Linux
-# or
-venv\Scripts\activate  # On Windows
-
-# Install Python dependencies
-pip install -r requirements.txt
-```
-
-### 3. Initialize Database
-
-```bash
-cd backend
-python -c "from database import init_db; init_db()"
-```
-
-This creates the SQLite database at `data/voicebox.db`.
-
-### 4. Install Qwen3-TTS (Optional)
-
-The Qwen3-TTS models are automatically downloaded from HuggingFace Hub on first use. However, you need to install the `qwen_tts` package:
-
-```bash
-pip install git+https://github.com/QwenLM/Qwen3-TTS.git
-```
-
-**Note:** Models (~2-4GB) will be automatically downloaded on first generation. This may take a few minutes depending on your internet connection.
-
-## Development
-
-### Start Backend Server
-
-```bash
-cd backend
-source venv/bin/activate  # Activate venv if not already active
-uvicorn main:app --reload --port 8000
-```
-
-Backend will be available at `http://localhost:8000`
-
-### Start Tauri Desktop App
-
-```bash
-# From project root
-bun run dev
-```
-
-Or manually:
-```bash
-cd tauri
-bun run tauri dev
-```
-
-This will:
-1. Start Vite dev server on port 5173
-2. Launch Tauri window pointing to localhost:5173
-3. Enable hot reload
-
-### Start Web App
-
-```bash
-# From project root
-bun run dev:web
-```
-
-Or manually:
-```bash
-cd web
-bun run dev
-```
-
-Web app will be available at `http://localhost:5174` (or next available port)
-
-## Building
-
-### Build Python Server Binary
-
-```bash
-./scripts/build-server.sh
-```
-
-This creates a platform-specific binary in `tauri/src-tauri/binaries/`
-
-### Build Tauri Desktop App
-
-```bash
-cd tauri
-bun run tauri build
-```
-
-Creates platform-specific installers:
-- macOS: `.app`, `.dmg`
-- Windows: `.exe`, `.msi`
-- Linux: `.deb`, `.AppImage`
-
-### Build Web App
-
-```bash
-cd web
-bun run build
-```
-
-Output in `web/dist/`
-
-## Generate OpenAPI Client
-
-After starting the backend server:
-
-```bash
-./scripts/generate-api.sh
-```
-
-This will:
-1. Download OpenAPI schema from backend
-2. Generate TypeScript client in `app/src/lib/api/`
-

-```
-
-## Troubleshooting
-
-### Backend won't start
-- Check Python version: `python --version` (needs 3.11+)
-- Ensure virtual environment is activated
-- Install dependencies: `pip install -r requirements.txt`
-
-### Tauri build fails
-- Ensure Rust is installed: `rustc --version`
-- Install Tauri CLI: `bunx @tauri-apps/cli install`
-- Check `tauri/src-tauri/Cargo.toml` for correct dependencies
-
-### OpenAPI client generation fails
-- Ensure backend is running on port 8000
-- Check `curl http://localhost:8000/openapi.json` returns valid JSON
-- Install openapi-typescript-codegen: `bun add -d openapi-typescript-codegen`
-
-## Model Downloads
-
-Models are automatically downloaded from HuggingFace Hub on first use:
-- **Whisper** (transcription): Auto-downloads on first transcription
-- **Qwen3-TTS** (voice cloning): Auto-downloads on first generation
-
-First-time usage will be slower due to model downloads, but subsequent runs will use cached models.
-
-## Next Steps
-
-1. ✅ TTS model loading implemented in `backend/tts.py`
-2. ✅ API routes implemented in `backend/main.py`
-3. Build React components in `app/src/components/`
-4. Connect frontend to backend via generated API client
-
-See [README.md](./README.md) for architecture details and [docs/](./docs/) for detailed documentation.

+### Backend Selection
+
+Voicebox automatically selects the best backend based on platform:
+
+- **Apple Silicon (M1/M2/M3)**: Uses MLX backend with native Metal acceleration (4-5x faster)
+- **Windows/Linux/Intel Mac**: Uses PyTorch backend (CUDA GPU if available, CPU fallback)
+
+The backend is detected at runtime via `platform_detect.py`. Both backends implement the same interface, so the API remains consistent across platforms.
