Free AI Tools/Grammar Checker

Grammar Checker

Fix grammar, spelling and punctuation without changing what you meant.

Free to use, no account needed. It has its own daily budget, separate from chat, that resets at midnight UTC.

Paste in a sentence, an email, or a full paragraph and this grammar checker corrects grammar, spelling and punctuation errors while keeping your meaning and tone intact. It shows exactly what changed, struck-through in red and added in green, so you can see and learn from every fix instead of just getting new text back.

How it works

  1. Paste or type the text you want checked into the box above.
  2. Click "Check grammar" (or press Ctrl/Cmd + Enter).
  3. Review the highlighted changes, or switch to the clean version and copy it.

Why use it

  • See every correction highlighted inline, not just a rewritten block of text.
  • Works on anything from a single sentence to a full email or paragraph.
  • A reading-ease score on the result shows how easy the corrected text is to read.

Frequently asked questions

What kinds of mistakes does it fix?

Grammar (subject-verb agreement, tense, word order), spelling, and punctuation. It preserves your original meaning, tone and formatting rather than rewriting the whole thing.

Is there a word limit?

There's no hard limit. It handles anything from a single sentence to a full email or a few paragraphs at once.

Does it store or reuse my text?

The check is a single request, and nothing from it gets saved to a chat history or account.

How is this different from my browser's built-in spellcheck?

A spellchecker mostly catches misspelled words. This also fixes grammar mistakes a spellchecker misses entirely, like subject-verb agreement, wrong tense, or awkward word order, and it explains the fix by showing it inline.
