Grammar &
Spell Checker.
Document-style checker that catches spelling typos, grammar errors, and writing recommendations — all in your browser. Issues appear with red wavy underlines on the left; suggested fixes show up as Replace with cards on the right. Accept applies the fix; Ignore dismisses it.
What the checker catches
• Capitalisation "hi xakh" → "Hi, Xakh." • Double spaces / typo runs "hello world" → single space • Repeated words "the the cat" → "the cat" • Wrong article a / an "a apple" → "an apple" • Missing punctuation "I'm fine" → "I'm fine." • Common typos "teh" → "the" · "recieve" → "receive" • Spaces around punctuation "word ." → "word." • Greeting style "hi name" → "Hi, Name."
All rule-based and 100% browser-local — your text never leaves the page.

Catch grammar, spelling and style issues live as you type. The whole thing runs in your browser tab, so it is ready the moment the page finishes loading.
