Cordial

Cordial is a French-language AI proofreading tool, delivered as a Chrome extension so it follows you across the web. As you type into websites, webmail, chat windows and content tools, its correction engine analyses each sentence and marks problems with clear, colour-coded underlines: red for spelling and blue for grammar, syntax and typography.

What sets Cordial apart from a simple spell checker is its focus on style. It flags not only misspellings but also agreement mistakes, incorrect tenses, redundant commas and unfortunate pleonasms, aiming to help you write more polished French rather than merely typo-free French. The publisher advertises a correction rate of around 90%.

The extension is published by the team behind cordial.fr and ties into a wider ecosystem. Cordial Analytics gives you a personal report of your most frequent errors, your average writing quality and your progress over time, while built-in dictionaries and over 200 pages of grammar guidance make the tool a learning aid as well as a proofreader. It integrates with everyday tools such as Gmail, Outlook, WordPress, Jira and Salesforce.
