No intermediate server, no account, no data collection. Your text only goes to the AI provider of your own key.
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.

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.
No, or only very partially: Grammarly is built for English. Correctify detects the language and fixes French as well as English.
Yes, and without the limits of Grammarly’s free tier. You use your own API key; Google Gemini’s free tier is enough for daily use.
No. Unlike Grammarly, which processes text in its cloud, Correctify sends your text straight to the AI provider of your key, with no intermediate server.
No. No account is needed: install Correctify, paste your API key once, and fix text.
