Free IELTS writing tool
IELTS Mistakes Finder
Paste your IELTS Academic or General Training answer and find the common mistakes that quietly cost band marks, from off-topic content and under-length writing to a weak overview, repetition, and the wrong register, each mapped to the four official criteria.
How to use it well
- 1. Paste a complete answer. Task 1 should be at least 150 words and Task 2 at least 250 words, since under-length writing is one of the most common mistakes the tool flags. See the Task 2 essay guide for structure.
- 2. Read each issue against its criterion. The four bands work together, so compare your weak points with the IELTS Writing band scores to see what a higher band looks like.
- 3. The tool is an automated self-check, not a band score. When you want a marked, corrected answer from a qualified teacher, use our IELTS writing correction service.
IELTS Mistakes Finder — common questions
What mistakes does the IELTS Mistakes Finder check for?+
It scans your Task 1 or Task 2 answer for the issues that most often cost band marks: off-topic or partial answers, under-length writing, a missing or weak Task 1 overview, repetition, and the wrong register. Each issue is mapped to one of the four official criteria.
Which IELTS criteria does it use?+
Every issue is tagged with one of the four official IELTS Writing criteria: Task Response (Task Achievement on Task 1), Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Each is scored 0 to 9 by real examiners.
Does this give me a band score?+
No. This free tool is an automated self-check that flags likely mistakes; it does not award a band. For an accurate band against all four criteria, use our paid human correction service, where a qualified teacher marks your answer.
Is this an official IELTS service?+
No. We are an independent writing correction service and are not affiliated with IDP, the British Council, or Cambridge. The tool offers practice feedback only and cannot predict your test-day result.
