How it works
- 1
Paste any English text: an essay, an email, a paragraph you're unsure about.
- 2
Click “Check grammar” and read the numbered error list.
- 3
Pay most attention to the “pattern to watch”: one recurring rule fixed beats ten one-off corrections.
- 4
Re-check a fresh piece of writing in a few days to confirm the pattern is gone.
Good to know
Errors versus patterns
Learners don't make random mistakes. They make the same three or four mistakes repeatedly: articles before uncountable nouns, prepositions after particular verbs, tense drift in narratives, subject-verb agreement across long subjects. A hundred scattered corrections are worth less than identifying the one rule that accounts for a third of your errors. That's why every report groups repeats together and ends by naming your dominant pattern with a self-check strategy for it.
For IELTS candidates specifically
Grammatical Range & Accuracy is 25% of both writing tasks and the speaking test, and the descriptors count error-free sentences: Band 7 requires “frequent error-free sentences”, Band 6 tolerates “some errors” that rarely impede. Running your practice essays through the checker before the band-score checkers tells you whether your ceiling is grammatical accuracy or something else entirely, a diagnosis worth having before you spend weeks on vocabulary.
