Correct French, English, Spanish, Italian and Portuguese in any text field. Free, offline, no account. Korr fixes your mistakes right where you write: email, social media, chat, work tools. Five languages: French, English, Spanish, Italian and Portuguese. Select some text, press the ✓ button or Alt+Shift+C, and it is corrected. ━━━ 100 % OFFLINE ━━━ The checker ships inside the extension. Your text is never sent over the Internet: no server, no account, no tracker, no ads. No sign-up, no usage limit. Check it yourself: after the first load, cut your connection. Everything keeps working, because nothing ever needed to leave. ━━━ WHAT IT CORRECTS ━━━ • English: subject-verb agreement, compound tenses, French-speaker false friends, verb-governed prepositions, uncountable nouns • French: hard agreements, past participle with a fronted object, pronominal verbs, tense sequence, subjunctive, homophones, typography, SMS shorthand • Spanish: accents that change meaning, dequeísmo and queísmo, long-distance agreement, opening marks • Italian: grave accent written for the acute, missing h in avere, elisions, subjunctive • Portuguese: the final nasal your keyboard drops, impersonal haver and fazer, crasis in fixed phrases ━━━ YOU STAY IN CONTROL ━━━ Every change is listed, placed in its sentence and labelled: you reject the ones you do not want, one by one. A personal dictionary keeps your proper nouns and your jargon safe, and it stays on your device. When a correction is uncertain, Korr would rather do nothing than degrade your text. That rule governs the whole product, and it is measured: across 360 sentences, 174 of them already correct, none was damaged. ━━━ FAST ━━━ A correction takes a few milliseconds, and the checker is ready in under a second.
