How to use it

  • • Select any French text on a webpage.
  • • Right-click and choose Check French level, or click the toolbar icon.
  • • See the CEFR level, difficult words, and a simpler version in a popup.
Why isn't it on the Chrome Web Store?

It will be. The Web Store review process takes a few days; until then, “Load unpacked” is the fastest way to try it. The source is in the project's extension/ folder.

Does it send my text anywhere?

The extension sends the selected text to https://french.aatechax.com/api/analyze to score it — same backend as this site. No accounts, no tracking, no storage on our side.
