Our verdict on Antidote
Antidote is writing-assistance software from Druide informatique for people who write in English or French. It combines grammar, spelling, punctuation and style correction with reformulation suggestions, dictionaries, language guides and tools for desktop, web and mobile use. The product line includes Antidote 12 for Windows and Mac, Antidote Web, and Antidote Mobile for iPhone and iPad. It suits writers, professionals and households that want more than basic browser proofreading, especially when detailed language references and desktop document support matter.
Pricing is subscription-based and billed annually. The vendor's pricing page lists Personal and Family plans for one language or for English and French. Personal plans cover one user, while Family plans support up to five household users. Every listed plan includes Antidote 12, Antidote Web and Antidote Mobile. First-year prices are CAD 59.95, 89.95, 99.95 and 149.95 across the four options, followed by annual renewal prices of CAD 48, 72, 80 and 120. A 30-day trial gives prospective buyers time to assess the workflow before committing.
Antidote's main distinction is breadth across writing environments. Browser connectors support Chrome, Firefox, Edge and Safari, while Connectix integrates with Microsoft Word, Excel, PowerPoint, Outlook, Microsoft 365 web apps, Google Docs, Gmail, Thunderbird, LibreOffice, Adobe Creative Cloud, Apple Mail and Safari. Anti-Oops! checks email errors, attachments and abrasive tone; multi-document correction handles plain text, HTML, Markdown and LaTeX files. Choose Antidote for deep English or French proofreading across devices and applications. It is less suitable for buyers seeking a free tool, monthly billing or broad language coverage beyond its two supported languages.
