Grammar Checker
Corrected text plus a plain-English list of what changed and why.
Free to use — fair-use limit of 15 AI runs per hour. Results are AI-generated: always review before publishing.
The HN Solutions Grammar Checker fixes grammar, spelling and punctuation while keeping your voice — and unlike most free checkers, it shows you a plain-English list of what it changed and why, so you actually learn from the corrections. No account, no premium nag, no browser extension required.
How to use the grammar checker
- Paste your text — emails, essays, applications, posts.
- Click Check grammar.
- Copy the corrected version, and skim the “What changed” list — that is where the learning happens.
Frequently asked questions
Does it change my writing style?
No — it is instructed to keep the author voice and only fix errors. Formality changes are the paraphrasing tool's job.
Which English does it use?
It auto-detects — if your text is in British English it corrects to British conventions, and likewise for American.
Is it better than my word processor?
It catches contextual errors (their/there, its/it's, subject–verb agreement across clauses) that basic spellcheckers miss, and explains each fix.
Is my text private?
Your text is processed to generate corrections and is not stored on our site.
Draft with the AI writer, tighten with the paraphraser, and confirm length with the word counter.
