I Made a Free AI Grammar Checker
Grammarly, ProWritingAid, Hemingway — great tools, but they all push you toward paid plans. I wanted something dead simple: paste text, get corrections, no signup.
So I built grammaraicheck.com.
Features
- Grammar & spell check — catches the usual suspects (their/there/they're, who/whom, affect/effect)
- Style suggestions — flags passive voice, wordy sentences, weak adverbs
- Text history — saves last 10 checks in localStorage, no account needed
- 24 writing guides — covers English word order, Flesch reading score, commonly confused words, and more
How It Works
- Paste or type your text
- Click "Check"
- Get inline corrections and suggestions
- Copy the fixed version
The AI backend handles grammar detection. The frontend is vanilla JS under 100KB.
Tech Choices
- Static HTML — no framework overhead
- localStorage for history (private by default — nothing leaves your browser until you click "Check")
- Cloudflare Pages for hosting
Why Another Grammar Tool?
Most free grammar checkers have a 500-word limit or require an account. I wanted something I could share with friends without saying "you'll need to sign up first."
Try it: grammaraicheck.com
Feedback welcome! What grammar rules do you wish free checkers handled better?
