Antidote vs Grammarly

Antidote

• 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

Grammarly

• People who write across many apps and want the same checks in each
• Teams of up to 149 that need a shared style guide and brand tone
• Students who want citation, plagiarism and AI-detection checks in one editor

Antidote

• 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.

Grammarly

• The Free plan is capped at 100 AI prompts a month and leaves out full-sentence rewrites and tone adjustments.
• Pro costs $30 per member a month on monthly billing, against $12 a month when billed annually.
• Pro stops at 149 seats; larger organizations need Enterprise, which is priced through sales.
• Advanced grammar, clarity and tone suggestions cover six languages; the other supported languages get spelling and basic grammar only.

Antidote

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.

Grammarly

Grammar, spelling and tone checks

Corrects spelling and grammar and shows the tone of a message on every plan. Full-sentence rewrites and one-click tone adjustments are part of Pro.

Works inside other apps

Desktop apps for Windows and Mac, extensions for Chrome, Safari, Firefox and Edge, and iPhone, iPad and Android apps bring suggestions into tools such as Gmail, Google Docs, Word and Slack.

Docs and AI agents

Docs is a browser-based document editor with agents including AI Grader, Citation Finder, Reader Reactions, Humanizer and Paraphraser. Some agents are limited to Pro.

Generative AI prompts

Drafts and reworks text from a prompt. The allowance is 100 prompts a month on Free, 2,000 per member on Pro and unlimited on Enterprise.

Plagiarism and AI detection

Scans a document for text that matches other sources and for passages likely to be AI-generated. The plans page lists both checks under Pro.

Team style controls

Pro team accounts get style guides, brand tones, knowledge share, snippets and usage analytics, so a group writes with the same terms and voice.
