BetterTTS - Offline Natural Text to Speech Reader/Read Aloud

BetterTTS turns your browser into an audiobook player — powered by AI voices trained exclusively on public domain audio, running entirely on your own computer. 🔒 ALWAYS AVAILABLE, NO CLOUD REQUIRED Cloud-based TTS (text-to-speech) services fail when servers go down — and lately, they go down a lot. BetterTTS runs 100% locally on your machine. No API calls, no server dependencies, no surprise outages. As long as your computer is running, BetterTTS works. Period. 📚 READ ENTIRE BOOKS WITH ONE CLICK Start reading on any chapter and walk away. With Auto-Next, BetterTTS automatically navigates to the next page when it finishes, reading through entire textbooks, web novels, or documentation without interruption. Do your chores, exercise, or relax while your computer reads for you. 🎙️ ETHICALLY TRAINED AI VOICES Unlike competitors that train on scraped or unlicensed voice recordings, BetterTTS uses the Kokoro TTS model — trained purely on public domain audiobooks.
