Correctify: the free alternative to Antidote
Antidote is a benchmark for French correction, but it’s paid software, focused on French and English. Correctify fixes text by AI, for free and with a right-click, everywhere you write. Here’s how they compare.
Free · No account · Windows, Chrome, Firefox & Thunderbird
Looking for a free alternative to Antidote? Antidote shines with its dictionaries and language guides, but its price and per-app setup can put you off. Correctify takes a different angle: an AI checker, with no account, that fixes text right where you write, from the browser to any Windows app.

Frequently asked questions
Is Correctify really free, unlike Antidote?
Yes. Correctify is free and ad-free. You use your own API key: with Google Gemini’s free tier, everyday text correction costs nothing.
Does Correctify fully replace Antidote?
For fixing spelling, grammar and style as you write, yes. Antidote keeps the edge on dictionaries, detailed language guides and offline use.
Does Correctify fix French as well as Antidote?
Correctify relies on large AI models that handle French very well, including tricky agreements and clumsy phrasing. The approach differs: AI understands context instead of applying fixed rules.
Do I need to install software for each app?
No. The Correctify Windows app fixes text in any program via a shortcut, and the extensions cover the browser and Thunderbird. No connectors to install one by one.
