Install the preview

  1. Download and extract the ZIP into a folder you will keep.
  2. Open chrome://extensions in Chrome.
  3. Turn on Developer mode, then choose Load unpacked.
  4. Select the extracted folder containing manifest.json.

Reuse what you learn

Completed translations are kept without an automatic expiry. Repeat requests with the same text, languages, context, and model use the saved result.

Clear limits

Storage and request capacity are finite. When the service is busy, try again later. Previously stored results remain available.
