 ## 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.
+Voicebox is a **local-first voice cloning studio** -- a free and open-source alternative to ElevenLabs. Clone voices from a few seconds of audio, generate speech in 23 languages across 4 TTS engines, apply post-processing effects, and compose multi-voice projects with a timeline editor.

+- **Complete privacy** -- models and voice data stay on your machine
+- **4 TTS engines** -- Qwen3-TTS, LuxTTS, Chatterbox Multilingual, and Chatterbox Turbo
+- **23 languages** -- from English to Arabic, Japanese, Hindi, Swahili, and more
+- **Post-processing effects** -- pitch shift, reverb, delay, chorus, compression, and filters
+- **Expressive speech** -- paralinguistic tags like `[laugh]`, `[sigh]`, `[gasp]` via Chatterbox Turbo
+- **Unlimited length** -- auto-chunking with crossfade for scripts, articles, and chapters
+- **Stories editor** -- multi-track timeline for conversations, podcasts, and narratives
+- **API-first** -- REST API for integrating voice synthesis into your own projects
+- **Native performance** -- built with Tauri (Rust), not Electron
+- **Runs everywhere** -- macOS (MLX/Metal), Windows (CUDA), Linux, AMD ROCm, Intel Arc, Docker
 
-Unlike cloud services that lock your voice data behind subscriptions, Voicebox gives you:
+## TTS Engines
 
-- **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
+Four engines with different strengths, switchable per-generation:
 
-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.
+| Engine | Languages | Strengths |
+|--------|-----------|-----------|
+| **Qwen3-TTS** (0.6B / 1.7B) | 10 | High-quality multilingual cloning, delivery instructions |
+| **LuxTTS** | English | Lightweight (~1GB VRAM), 48kHz output, 150x realtime on CPU |
+| **Chatterbox Multilingual** | 23 | Broadest language coverage |
+| **Chatterbox Turbo** | English | Fast 350M model with paralinguistic emotion/sound tags |
