## Key features

- **Corrector:** Flags spelling, grammar and typography errors with a tooltip explaining each one, and its filters pick out repetition and non-inclusive wording.
- **Reformulation:** A subscription-only mode that uses generative AI trained by Druide's linguists to rewrite, retouch, soften or shorten a passage or a segment of it.
- **Dictionaries:** Definitions link on to synonyms, antonyms, word combinations, conjugations and word families, with audio pronunciation for subscribers.
- **Language guides:** 578 articles cover grammar, style, spelling and punctuation, and the corrector's tooltips link to the article that explains the rule in question.
- **Anti-Oops! for email:** Steps in when Send is clicked to prompt a final check of the email, confirm that the intended attachments are included, and flag wording that may be badly received.
- **Connectors to other software:** The free Connectix utility links Antidote 12 or Antidote Web to more than 90 applications, so corrections are applied in the original document.

## Good for

- People who write in both English and French
- Editors and translators who want explanations with each correction
- Families: one subscription covers five users
- Organizations that need a corrector installed without external servers

## Worth knowing

- Druide's store lists prices in Canadian dollars, plus taxes where applicable.
- The subscription is billed once a year with no monthly option, and store purchases are not refundable.
- English and French are separate: one language is included, and having both costs CA$89.95 instead of CA$59.95.
- There is no native Android app. Android, Chromebook and Linux users work in Antidote Web, and Antidote Mobile has no corrector of its own.
