Three steps to error-free writing
Forgely's AI grammar checker uses Claude — one of the world's most capable language models — to analyze your text for errors and explain every correction clearly.
Paste your text
Paste up to 1,000 words into the box. Works with emails, essays, blog posts, cover letters, reports — any writing you want checked.
Click Check Grammar
Claude reads your text deeply — not just scanning for rule violations, but understanding context to catch errors that simple checkers miss.
Copy the fixed text
See your corrected text, your writing score, and a full list of corrections with explanations. Copy with one click.
A grammar checker that actually teaches you
Grammar & syntax
Subject-verb agreement, tense consistency, article errors, pronoun reference, sentence fragments, and run-ons — caught and corrected.
Spelling & homophones
Beyond typos — Claude catches contextual errors like there/their/they're, its/it's, affect/effect that spell-checkers miss completely.
Punctuation
Missing commas, apostrophe errors, incorrect colons and semicolons, and hyphenation — fixed with clear explanations.
Style suggestions
Passive voice overuse, wordiness, and unclear phrasing flagged as style suggestions — distinct from hard errors.
Explains every correction
Every issue includes a clear explanation of the rule or reason — so you learn, not just copy-paste a fix.
Private by design
Your text is processed and not stored. No account needed, no browser extension, no data collection.

It catches grammar errors (subject-verb agreement, tense, articles), spelling mistakes and homophones (there/their/they're), punctuation issues (missing commas, apostrophes), and style problems (passive voice, wordiness, unclear phrasing).
Very accurate. Forgely uses Claude, one of the most capable AI language models. It understands context — not just rules — so it catches errors that rule-based checkers miss, and avoids false positives.
The free tool checks up to 1,000 words at a time. For longer documents, you can check sections separately.
No. Your text is sent directly to the AI for processing and is not stored on any servers. Privacy-first by design.
Yes. The AI understands academic style and handles formal writing well. It won't incorrectly flag discipline-specific terminology or formal constructions.
Forgely requires no account or browser extension, is completely free with no premium tier, and uses Claude AI which understands context more deeply. It also explains every correction clearly, so you learn as you fix.
Yes — it's especially helpful for ESL writers. Claude catches common article errors (a/an/the), preposition mistakes, and awkward phrasing that rule-based tools often miss.
