Corrected text
What was fixed
Corrections are generated by AI. Give the result a quick read before you use it.
This free AI grammar checker reviews your text for spelling, grammar and punctuation mistakes, then returns a clean version you can copy straight into your email, document or post. Unlike a simple spellchecker, it understands context: your for you're, its for it's, subject-verb agreement, misplaced commas and awkward tense shifts. It preserves your wording and tone instead of rewriting your style, and it lists each correction so you can see exactly what changed and learn from it.

Frequently asked questions
Is this grammar checker really free?
Yes. There is no signup, no word limit tricks and no premium tier hiding the real corrections. Paste your text, click the button and copy the result. It is one of the free tools we offer alongside Mail Merge for Gmail.
Which languages does it support?
The checker replies in the language you write in, so English, Spanish, French, German, Portuguese and most other major languages work. Corrections are most thorough in widely spoken languages, where the AI has seen the most real-world writing.
Will it change my writing style?
No. It is instructed to fix mistakes while preserving your meaning, tone, formatting and line breaks. It will not shorten your text, swap your vocabulary for fancier words or restructure your sentences unless a sentence is grammatically broken.
What kinds of mistakes does it catch?
Spelling errors, verb tense and agreement issues, punctuation problems, wrong homophones like their and there, article misuse and capitalization slips. Because it reads the whole sentence in context, it catches errors a word-by-word spellchecker misses.
Is my text stored anywhere?
Your text is sent to the AI model to generate the corrections and is not published anywhere on this site. Avoid pasting passwords, confidential contracts or other sensitive data into any online tool, this one included.
Why should I check grammar before sending an email campaign?
Typos are one of the fastest ways to lose credibility with a prospect or customer, and they hurt reply rates. Checking your template once before a mail merge means every recipient gets the polished version, so the few seconds spent here multiply across your whole list.
