AI Grammar Explainer
About this tool
Corrections that come with the rule behind them, and the repeated mistakes named as patterns.
A grammar checker that silently fixes your writing leaves you making the same mistake next week. The correction is only useful when you can see why it was wrong.
Every change here comes with the original, the correction and the rule in one line. More usefully, repeated errors are grouped and named as a pattern — if you drop articles before abstract nouns, that is one habit to fix rather than eleven separate corrections to memorise. It closes with the single change that would improve your writing most, which for most learners is a structural habit rather than any individual rule.
How to use
- Paste your English text, set your level so the explanations are pitched right, and choose what to focus on

No. Your input is sent to the AI provider this site is configured to use purely to generate your result, and is not stored here afterwards. There is no account for it to be attached to. Even so, keep passwords, financial details and other people's private information out of it.
The site owner selects one model that powers every tool here, so there is nothing for you to configure. Describe what you need, press Generate, and read the result before you use it.
