Questions people ask
Is this grammar checker free?
Yes. The quick checks run instantly in your browser at no cost, and the AI grammar check is free with a fair-use limit of about 15 checks every 10 minutes. No account is needed.
What does the AI grammar checker fix?
Spelling, grammar (subject–verb agreement, pronouns, tense), punctuation, commonly confused words (your/you’re, their/there, affect/effect) and capitalisation. It keeps your style and meaning, and lists every change with the reason so you can accept or ignore each one.
Does it work for British and American English?
Yes. It keeps the spelling convention your text already uses: “organise” stays British, “organize” stays American. It also works for other languages; the AI answers in the language of the text.
Is it better than a spell-checker?
A spell-checker only catches words that do not exist. “Their are a few point’s” contains no misspelled words, but three errors. An AI grammar check reads the sentence in context, so it catches confused words and agreement errors too.
Will it change my meaning?
It is instructed to change only what is needed to fix errors and to keep all names, numbers and dates. Still, read the list of changes before you send anything important.
