Question 1

Is my text sent anywhere?

Accepted Answer

No. The in-browser AI, Chrome’s built-in AI and the offline method all run on your device. The first time you use the in-browser AI, your browser downloads the model from Hugging Face, a public model host (about 800 MB, once); your text is never sent.

Question 2

Which browsers and devices can use it?

Accepted Answer

The in-browser AI runs in recent Chrome, Edge and Firefox, and works best on a computer with 8 GB of memory or more. It is slower and makes more mistakes than online AI services, and on a phone it can be very slow or run out of memory. Chrome’s built-in AI shows only where this browser has it. The offline method works everywhere.
