Grammar, spelling, and the thing Grammarly passes clean
A 49,000-word dictionary in US and British English, 25 grammar rules, and the AI phrasing a correctness checker has no reason to flag. All in one pass. No account needed.
What it checks
- Misspellings, against a 49,000-word dictionary accepting US and British spellings
- Homophones: their/they’re/there, your/you’re, lose/loose, then/than
- Missing apostrophes, subject-verb agreement, wrong verb forms after an auxiliary
- Repeated words, a/an, spacing and repeated punctuation
- Modern vocabulary the standard dictionaries predate: roadmap, onboarding, webhook
- AI phrasing, sentence rhythm and readability alongside
Why a correctness checker is not enough any more
“Delve into the rich tapestry of modern commerce” is flawless English. Every word is spelled correctly, the grammar is impeccable, and a grammar checker will pass it without comment. It also reads exactly like a machine wrote it, which is the thing your reader notices first.
That gap did not matter much before 2023. It matters now, because a first draft is increasingly generated rather than typed, and correctness is the one thing generated text never gets wrong.
So this covers what a proofreader covers (misspellings, homophones, apostrophes, agreement, verb forms, doubled words) and then keeps going into vocabulary, sentence rhythm and formatting. Two things it honestly does not do: plagiarism checking, which needs an index of the web, and comma style, which is ambiguous enough to be house style rather than rule.
