Kokoro Web Autor: Ajay Tripathi

Kokoro Web reads text aloud in your browser using kokoro-tts running on your own computer. Nothing is sent to the cloud, and the developer does not receive your text or audio.

• Popup — paste text, choose voice and speed, play/pause/stop
• Context menu — select text → right-click → Read with Kokoro
• Read page — right-click → Read page with Kokoro, or use Read page in the popup
• Read-along sidebar — follow along while text is spoken (Firefox sidebar)

Setup

This extension is a bridge only. It does not include the TTS engine or voices. Before use:

1. Install kokoro-tts and download the model files
2. Install the native messaging bridge:
3. pip install kokoro-web
4. kokoro-web-setup firefox
5. Restart Firefox and click Test connection in the extension

See the GitHub README for detailed setup steps.

Privacy

When you choose to read text, that text is sent from the extension to a native messaging host on your computer (kokoro-web-host), which calls your local kokoro-tts binary. Temporary files are deleted after synthesis.

• No accounts, no analytics, no ads
• No data sent to the developer or third-party servers
• Preferences (voice, speed, paths) may sync via Firefox Sync if you enable it
