12 Grammar Rules You Can Check Client-Side — No API, No Backend

I built a free, embeddable grammar checker widget that catches 12 common English errors entirely client-side. No API key, no backend, no tracking.

The 12 Rules It Catches

  • i am → "I am" (capitalize I)
  • alot → "a lot" (misspelling)
  • your going → "you're going" (your/you're confusion)
  • theyre → "they're"
  • should of → "should have"
  • would of → "would have"
  • could of → "could have"
  • more [word]er → double comparative, like "more faster"
  • its going → "it's going"
  • there house → "their house"
  • your welcome → "you're welcome"
  • Common misspellings via pattern matching

Embed It

  width="100%" height="350" frameborder="0"
  title="Free Grammar Checker">
</iframe>
Enter fullscreen mode Exit fullscreen mode

One line of HTML, that's it. The widget is mobile-responsive and pure vanilla JS — no dependencies.

I built this because every "free grammar checker" I found was either an ad farm or wanted my email. This one runs in the browser and your text never leaves the page.
