Grammar CheckerNEW
Spot common spelling, punctuation and style slips in your text
Checking your access…
AllFreeTool is a free online grammar checker that runs entirely on your own device. Choose Chinese or English, paste your text, and the tool looks for common mistakes such as repeated words, misused punctuation, a missing capital letter at the start of a sentence, and well-known awkward sentence patterns, then reports each issue with the word count, character count and sentence count. Nothing is uploaded.
It suits drafting an email or a report, checking a translation that is not quite right, or reviewing a piece of writing before you send it to a client or a teacher. Because the rules are applied locally and instantly, you can run it as often as you like without any account, and the text never leaves your browser.

Common questions
Is this a full English grammar checker?＋
No, it is a rule-based checker that catches a practical set of common errors such as duplicated words, incorrect punctuation, a missing capital letter and a handful of frequent awkward constructions. It gives quick feedback on a draft, but it is not a substitute for a human editor on important writing.
How do I use it for Chinese text?＋
Switch the language option to Chinese and the tool applies the Chinese rules, which cover repeated characters, full-width and half-width punctuation mixing, and common wording problems. The statistics change to match, counting Chinese characters rather than English words.
Will it rewrite my text for me?＋
No. The tool reports what it found and where, and leaves the wording to you, which is usually what you want for anything professional. Because it does not send your text anywhere, you can also safely use it on sensitive or unpublished material.
Is my text uploaded to a server?＋
No. The rules are applied entirely inside your browser with no network request, so the text never leaves the device and is not stored. The checker also keeps working when you are offline.
