Correctify: the free alternative to MerciApp
MerciApp fixes French by AI, but limits free corrections and runs on a subscription. Correctify fixes text with no quota or account, and no intermediate server. Here’s the comparison.
Free · No account · Windows, Chrome, Firefox & Thunderbird
MerciApp is a polished French tool, but its model relies on a subscription and a limited free quota. If you want a free MerciApp alternative with no enforced quota or account, Correctify builds on your own API key: you stay in control of your data and your cost.

Our verdict
MerciApp is well integrated and built for French, but its limited free quota and subscription can add up. Correctify relies on your own API key: no enforced quota, no account, and your text never goes through an intermediate server. To fix text freely while keeping control of your data, it’s the most direct free alternative.
