The short version

Errors fixed. Your voice untouched.

Most grammar tools quietly rewrite your sentences while they're at it — smoothing tone, swapping words, changing rhythm. This one doesn't. It looks only for genuine mistakes: spelling, punctuation, agreement, tense — and fixes exactly those, leaving every correct sentence exactly as you wrote it.

That distinction matters if you have a voice worth keeping. Paste your draft, get it back clean, and nothing about how you write has changed — just the parts that were actually wrong.

What it catches

A focused pass over the errors that actually trip up readers — not a style rewrite in disguise.

🔤

Spelling mistakes

Typos, missing letters, and commonly confused words like "their/there" or "its/it's".

🧩

Subject-verb agreement

"The team are ready" → "The team is ready" — mismatches that slip past a quick read-through.

✂️

Punctuation

Missing commas, stray apostrophes, run-on sentences, and misplaced periods.

🔁

Word repetition & tense shifts

Accidentally repeated words and sentences that drift between past and present tense.
