Antidote is a grammar checker designed in Quebec for French and English. It proofreads your writing in Word, Outlook, your webmail, or your browser, explains each error, and suggests the correction. It also brings together dictionaries and grammar guides. Since version 12, it can rephrase a sentence for you: shorten it, soften it, rewrite it.
Antidote has no free plan. The recommended plan to start with: Antidote+ Personal, one language, $59.95 the first year, then $48 per year. Prices checked on October 3, 2026 on the vendor’s official page.
AntidoteThe reference grammar checker for error-free FrenchWho it’s for: anyone who writes a lot in French and does not want to let a single error through: letters, reports, proposals, contracts, publications.
Antidote proofreads your whole text in one pass: spelling, grammar, agreement, punctuation, typography. For each error, it suggests the correction and explains the rule. Filters also spot repetitions and non-inclusive terms.
Antidote suggests several rewrites of a sentence, true to your idea. Five panels: “Réécrire” (rewrite), “Retoucher” (touch up), “Raccourcir” (shorten), “Modérer” to soften the tone, and “Épicéniser” for wording that addresses everyone.
When you send an email, Antidote proofreads it. It stops you if errors remain, if you mention an attachment without adding it, or if the tone could hurt.

Antidote has no free plan, but the 30-day trial is enough to judge it on your real texts. If you write in French every day, Antidote+ Personal in one language is the right choice. Choose the bilingual edition only if you also write in English. At a company, first ask whether a license already exists.
