Grammar Fixer

Three correction levels, and when each one is right

This is the setting that matters, and most checkers do not offer it. Light fixes only what is clearly wrong — typos, misspellings, missing punctuation — and leaves your phrasing exactly as you wrote it. Use it when the text already sounds the way you want and you are only hunting mistakes.

Standard is the default. It fixes errors and also tidies awkward constructions, which suits most email, coursework and everyday writing.

Thorough intervenes the most, reworking clumsy sentences as well as correcting them. It is the right choice when you are writing in a second language and want the result to read naturally to a native speaker, and the wrong choice when you have a distinctive voice you want preserved. If a Thorough pass comes back sounding like someone else wrote it, that is the setting, not a fault — run it again on Light.

Seeing what changed

By default you get the corrected text on its own, ready to copy. Turn Show Corrections on and the changes are identified for you, which is worth doing if you want to learn from the edits rather than just accept them — particularly useful for the same mistake you keep making. You can copy the result or download it, and there is a word count on the output.

What happens to your text

Unlike the PDF and image tools on ToolsHall, this one is not browser-only. Your text is sent to a language model to be corrected, so do not paste anything confidential — client data, unpublished work, anything under an NDA. Input is capped at 8,000 characters per check, roughly 1,200 words, so longer documents should be done a section at a time. Usage is limited to 30 checks an hour, which is what keeps it free and available without an account.
