AI IELTS Writing Checker Online: Band Score and Line-by-Line Corrections

What you get for each essay

• A band from 0 to 9 for Task Achievement or Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.
• An overall band calculated by the system as the mean of the four criteria, rounded with IELTS half-band rounding.
• Six to fourteen line-by-line annotations that quote your essay word for word, each marked as good, suggestion or error. Errors and suggestions include a fix.
• A "why not the next band" point for each criterion.
• Near-synonyms, high-band vocabulary and topic vocabulary, plus your essay rewritten one band higher with the key changes explained.
• Feedback in any of 11 interface languages. Quotes, corrections and vocabulary words stay in English; explanations use your language.

How to check an essay

• Choose the task and exam type, then paste the question and your essay.
• Sign in and verify your email with a 6-digit code.
• Start the score. It usually takes one to two minutes.

Scoring runs in a desktop browser at least 1024px wide. This page, the guides and the pricing page also work on mobile.

Limits you should know

• The score is an AI estimate against the public band descriptors, not an official IELTS result.
• In a test on 23 published examiner-marked sample scripts, the average error was 1.04 bands, and strong writing scored too low: about 1.2 bands low from band 6 to 7, and about 2.2 bands low at band 7.5 and above.
• The same essay can score slightly differently between runs. Compare trends across several essays.
• It checks every Task 1 figure only on the Academic questions on this site, where it has a transcript of the visual. It does not judge figures in a Task 1 question you paste yourself.

Common questions

Is this IELTS Writing checker free?

Partly. After you verify your email, you get one free AI score a day for 3 days, and a free score you don't use that day expires. Disposable email addresses are not eligible. Extra scores need a credit or a pass, and practising in the exam simulator is free.

Does it score the four official IELTS criteria?

Yes. Each criterion is assessed separately against summarised public band descriptors. The criteria are Task Achievement or Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.

Does it give line-by-line corrections?

Yes. Each report has six to fourteen annotations that quote your essay word for word, each marked as good, suggestion or error. Errors and suggestions include a fix.

How accurate is the band score?

It is a practice estimate and tends to score strong writing too low. On 23 published examiner-marked sample scripts, the average error was 1.04 bands, with 34% of scores within half a band and 72% within one band. The sample is small, so use the score to compare essays over time and not to predict an exact exam band.

Can ChatGPT mark my IELTS essay instead?

ChatGPT can give useful feedback, and its result depends on your prompt. ieltswrites applies a fixed process: separate criterion scoring, a calculated overall band and annotations quoted from your essay. It does not claim to be more accurate than ChatGPT.

Is ieltswrites connected to the official IELTS test?

No. ieltswrites is independent and is not affiliated with or endorsed by IELTS, the British Council, IDP or Cambridge.
