“Me and him was tired.” “Their going to the market.” “I has went.” Mistakes like these slip into emails, job applications and assignments all the time, especially when English is your second or third language — and they cost credibility out of proportion to their size.
This tool checks your text with LanguageTool, an established open-source grammar and style checker used by millions of people and built into many writing apps. It finds spelling mistakes, grammar errors such as subject–verb agreement and wrong tense forms, confused words like their/there/they're, punctuation and spacing problems, and — at the picky level — wordy or informal phrasing.
You get three views: the corrected text ready to copy, a highlighted comparison showing exactly what changed, and a table listing each issue with the rule's explanation and alternative suggestions. You stay in control; nothing is rewritten without showing you why.
To check your text, it is sent over HTTPS to LanguageTool's public API, which processes it and returns the corrections; LanguageTool's privacy policy (linked in the tool) explains how checked text is handled. As with any online checker, don't paste passwords, ID numbers or other confidential information, and remove client names from sensitive drafts before checking them.
How It Works
- Paste your text — up to 18,000 characters (roughly 3,000 words) and choose the language variant: US, UK, Australian or Canadian English, or one of several other languages.
- Check — the text is sent to the LanguageTool API, which runs thousands of grammar and style rules plus a spell-checker and returns each match with its position, explanation and suggested replacements.
- Review and copy — the tool applies the first suggestion for every match, shows deletions and insertions side by side, and lists every issue so you can accept alternatives by editing the corrected text.
Compatibility & Support
Supported Input → Output Formats
- Input: plain text typed or pasted — sentences, emails, essays, posts
- Languages: English (US, UK, AU, CA), German, French, Spanish, Portuguese, Dutch, or automatic detection
- Output: corrected text, highlighted change view, issue table with explanations
Unsupported Formats
Urdu, Hindi, Arabic and most South Asian languages aren't covered by the free LanguageTool service. Formatting (bold, links, bullet lists) is not preserved — the tool works on plain text. Automated checkers catch mechanical errors well but can miss wrong facts, awkward logic or a word that is spelled correctly but wrong in context.
File Size Limits
Up to 18,000 characters per check. The free LanguageTool API also limits how many requests one connection can make per minute; if you see a “busy” message, wait a minute and try again.
For long documents, check a section at a time — the highlighted comparison is easier to review in smaller pieces anyway.
Who Should Use This Tool?
- Students: A student checks a scholarship personal statement for grammar before submitting it to a portal that doesn't allow edits afterwards.
- Freelancers & Designers: A freelancer proofreads a client proposal and cover email so small errors don't undercut a strong pitch.
- Office Professionals: An office manager checks an official notice to staff for tense and agreement errors before it is printed and posted.
- Developers: A developer proofreads release notes and README text before publishing them on GitHub.

Why This Tool Beats the Alternatives
- Uses a real, rule-based grammar engine rather than simple word swaps.

- Clear about where the text goes and why.
- No account needed and no daily word quota on this page.
- Explanations help you learn the rule, not just fix one sentence.
Pro Tips
- Choose the right English variant — UK English flags “color”, US English flags “colour”.
- Read the issue table before copying: the first suggestion isn't always the one you want.
- Paste the corrected text into the Word Counter if you also need to meet a word limit.
