How to use the Grammar Checker

  1. Paste or type your text.
  2. Press Check grammar and wait a few seconds.
  3. Read the list of fixes to see what changed and why.
  4. Copy the corrected text.

Your text is not stored. Unlike our other tools, the AI tools send your text securely to our AI provider (Groq) to process it. We don’t save the text, only how many words you used. Read our privacy policy.

What the grammar checker fixes

  • Spelling: “recieve” → “receive”, “definately” → “definitely”
  • Grammar: “he go to school” → “he goes to school”, “less mistakes” → “fewer mistakes”
  • Punctuation: missing full stops, commas and apostrophes (“its” and “it’s”)
  • Capitalisation: sentence starts, names and “I”

It keeps your words, tone and style, and only changes what is wrong. British and American spelling are both kept as you wrote them.

Worked example

Before: “me and my freind was going to the libary yesterday but it were closed.”

After: “My friend and I were going to the library yesterday, but it was closed.”

The list of fixes shows each change, such as “freind → friend (spelling)”, so you can learn from your mistakes.

Tips

Check long documents a few paragraphs at a time (up to 500 words each). After checking, use the word counter to make sure you are within your word limit, or the paraphrasing tool to reword sentences that still feel clumsy.

Frequently asked questions

Will it change my writing style?

No. It is told to fix only spelling, grammar, punctuation and capitalisation mistakes and to keep your words, tone and style.

Does it work with British English?

Yes. It keeps the spelling you use, so “colour” and “organise” stay British and “color” and “organize” stay American.
