AI Grammar Fixer
Paste your text and get every grammar, spelling, and punctuation error corrected — while keeping your original writing style and voice intact.
What it corrects
The grammar fixer corrects spelling mistakes, grammatical errors, incorrect punctuation, misused words (their/there/they’re, its/it’s), missing apostrophes, double negatives, subject-verb agreement errors, and sentence fragments. It works on text at any length, from a single sentence to several paragraphs.
Unlike a full rewrite, the grammar fixer only touches what is actually wrong. If your sentence structure is correct but your phrasing is awkward, it leaves that alone — use the Writing Improver for that.
When to use it
- Before sending a professional email — a quick check to catch typos and grammar slips that could undermine your credibility
- Non-native English writing — checking text written in English as a second or third language before sending it to a native speaker
- Social media posts — catching errors before they go live and cannot easily be edited
- Documents and reports — a final pass before sharing a draft with colleagues or submitting it
- Messages typed quickly — autocorrect misses and typos from fast typing on a phone
Before and after

Will it rewrite my text entirely?

Does it support British and American English?
The AI corrects based on standard usage and will match the variety present in your text. If you are writing British English, it will not change “colour” to “color”.
