Frequently asked questions
- Is the grammar checker free?
- Yes, and there is no sign-up. A fair-use limit of a few requests per minute keeps it available to everyone.
- What does it check?
- Grammar, spelling, punctuation, subject–verb agreement and clarity. It leaves sentences that are already correct alone rather than rewriting your text for the sake of it.
- Does it show me what changed?
- Yes. Alongside the corrected text you get a list of each issue found and the fix applied, so you can learn from it instead of pasting blindly.
- Can it change the tone of my writing?
- Optionally. Leave the tone on 'Keep original tone' for corrections only, or pick formal or casual to have the wording adjusted without changing your meaning.
- How much text can I check at once?
- Up to 5,000 characters per check — roughly two pages. For longer documents, run it a section at a time.
- Is my text stored?
- No. It is sent to the model to produce the correction and is not saved on our servers or used for training.
