Questions

Is it really free?

Yes. There is no account, no subscription and no usage cap. The default on-device engine runs on your computer, so it costs nothing to run. If you prefer a cloud model, Groq gives free API keys, and OpenRouter has free models too.

Do I need an account or an API key?

No account, ever. On Chrome desktop with on-device AI available, you don't need a key either. Otherwise you can paste a free Groq key in about a minute, or point it at Ollama or LM Studio on your own machine.

Which languages does it support?

Replies and rewrites work in any language with Groq, OpenRouter or a local model. Chrome's on-device model currently supports English, German, Spanish, French and Japanese; for other languages, use one of the other engines.

What happens to my text?

With on-device or local engines, nothing leaves your computer. With a cloud engine, only the text you select is sent, directly to the provider you chose, using your own key. We run no servers and collect no analytics.

Where does it work?

In regular text fields and editors on most websites: webmail, social networks, chat apps, support desks, CMS editors and more. Google Docs is not supported yet because it draws text on a canvas.

Which browsers?

Chrome and other Chromium browsers (Edge, Brave, Arc) through the Chrome Web Store, and Firefox through Firefox Add-ons.
