Text to speech FAQ
Is this free AI text to speech?
Yes. The Kokoro workflow can run in the browser without an account. The model downloads on first use and is cached by the browser when possible.
Can I export MP3?
Yes. Generate the speech, choose MP3, and the page will transcode the WAV result locally with FFmpeg.
How should I handle long text?
Use Long Text mode. The page splits the script into smaller segments, generates them in sequence, and can package the results for download.
