FreeCorrector – French & English Grammar Checker by BenjiBurn

FreeCorrector is a free spell checker and grammar checker for English and French. It underlines your mistakes as you type, everywhere on the web: Gmail, Outlook, Google Docs, Discord, Notion, ChatGPT, social networks, forms… Click the underlined word and it’s fixed.

• Free: no account, no subscription, no ads.
• No AI: FreeCorrector never rewrites your sentences. It flags the mistake, explains the rule and suggests the fix; you decide.
• 100% local: everything is checked inside your browser. Nothing is sent over the Internet, and it even works offline.
• English and French detected automatically, sentence by sentence, even in a text that mixes both.

<b>How it works</b>
• Mistakes are underlined as you type: red for spelling, orange for grammar, blue for typography.
• Click an underlined word to see the recommended fix, with the other suggestions right below.
• A counter at the bottom right of the field shows how many mistakes there are; click it for the full list. Ctrl+Shift+F fixes every mistake in the field at once.
• The proofreader page (toolbar menu) lets you paste a long text and fix everything in one click.
• A French verb conjugator: every tense of any French verb, from the toolbar menu or from the bubble of a conjugation mistake.

<b>What it catches</b>
English: your/you’re, its/it’s, their/there/they’re, subject-verb agreement, tenses, “should of”, typos and more. French: agreement, conjugation, homophones, past participles, subjunctive, accents, capitals and punctuation.

<b>Also</b>
• Personal dictionary.
• Turn it off on the sites you choose, or on the current page with Ctrl+Shift+1.
• Right-click selected text: “Check with FreeCorrector”.
• Picky mode for fine typography.
• Undo with Ctrl+Z after a fix.
• Also for Thunderbird, and as a Windows app (Word, Outlook, Notepad…).

<b>Open source</b>
FreeCorrector is free software (GPL v3). It builds on two open-source engines, Harper for English and Grammalecte for French, and adds its own rules and context-aware ranking of suggestions. Source code: https://github.com/BenjiBurn/FreeCorrector
