Free Text to Speech — Realistic AI Voices, 100% Private

Yes, we use the state-of-the-art Kokoro 82M-parameter AI model which produces high-fidelity, human-like speech with natural intonation and emotion. You can choose from 28+ studio voices spanning US and UK English accents, with both male and female options — all running entirely on your device.

No. The AI model runs entirely in your browser using WebAssembly. Your text never leaves your device, providing 100% privacy for your content.

You can generate up to 5,000 characters at a time. This is the optimal chunk size for on-device neural processing — it ensures consistent speech quality without putting too much pressure on your device's memory. For longer documents, simply generate them in multiple segments.

AI Text-to-Speech is a technology that converts written text into spoken audio using artificial intelligence. Unlike older robotic voices, modern AI TTS (like our Kokoro models) uses deep learning to understand context and produce natural-sounding speech with correct emphasis and human-like emotional range.

Our tool runs high-performance neural networks directly in your browser using WebAssembly (WASM). When you click generate, your device’s CPU performs the complex calculations required to synthesize audio samples from your text. Because the "brain" of the AI lives in your browser, your text is never uploaded to an external server, ensuring maximum privacy.

Submind provides a professional-grade TTS experience that is completely free and private. Content creators use it to generate voiceovers for social media without recording equipment. Educators produce narration for online courses in seconds. And because the AI runs entirely in your browser, sensitive scripts never leave your device. With 28+ studio voices, unlimited free generations, and no account required, it’s the most secure and accessible way to generate AI speech.
