Quick answer
The FiftyGPT Grammar & Spell Checker reviews your text for grammar, spelling, and punctuation mistakes and returns a corrected version with each issue explained. Pick US or UK English, and either fix errors only or also improve style and clarity. It is free and needs no account.
How to use the Grammar & Spell Checker
- Paste the text you want checked into the box.
- Choose your goal — fix grammar, spelling, and punctuation only, or also improve style and clarity.
- Select US or UK English so spellings match your region.
- Select Check Grammar and read the list of issues next to the corrected text.
- Accept the fixes you agree with and keep your own wording where it matters.
When it helps most
- Before you hit send — proofread an email, message, or cover letter.
- On work you have read too often — catch the slips your eyes skip after the tenth read of an essay.
- For second-language writing — tidy grammar and spelling while keeping your meaning intact.
Example. Paste "their going to the store" and it flags the mix-up, suggesting "they're going to the store" with a short note on their, they're, and there.
What it does not do
It checks grammar and spelling — it is not an AI detector or a plagiarism scanner. For those, use FiftyGPT's AI Detector and originality tools.
