Korr fixes French, English, Spanish, Italian and Portuguese right where you write: no account, no limit, no connection needed. Everything runs on your device. There is no analysis server, and you can check it: cut your connection after the first load and it keeps working. Every change is listed and can be rejected one by one. When a fix is uncertain, Korr changes nothing. Website and Chrome extension (Alt+Shift+C) for all five languages; Windows app (Ctrl+Alt+C) for French and English.
