Correctify: a privacy-first Grammarly alternative

Grammarly is built for English and requires an account. Correctify fixes English and French alike, by AI, for free and with no account, right from a right-click. Let’s compare.

Free · No account · Windows, Chrome, Firefox & Thunderbird

Grammarly is a great writing assistant… in English. If you also write in French, that’s its weak spot: it doesn’t really fix French. If you want a Grammarly alternative that handles French, with no account or subscription, Correctify ticks the boxes and keeps your text private.

Our verdict

If you mostly write in English, Grammarly is a safe bet. But as soon as French is involved, it falls short. Correctify fixes French and English alike, with no account or subscription, and without sending your text to a third-party server. To write error-free in both languages, it’s the obvious alternative.
