You have an essay and you want to know your band. You can paste it into an AI checker, ask ChatGPT, run a grammar tool, read official sample answers, or pay a teacher. They sound similar, but they do very different jobs. This guide shows what each one is good for, so you can pick the right help at the right time. We make VoyaLang, an IELTS writing checker, and we point it out where it fits.
The short answer
The best free IELTS writing checker is not the one that gives you the highest band. It is the one that shows you what to fix. A good one gives you a band for each of the four criteria, explains each band using your own sentences, names the type of every mistake, and treats Task 1 and Task 2 differently. It is also honest about what it cannot do.
No free tool gives you an official score. Only the real IELTS test does that.

| ChatGPT and other AI chats | Yes | Only if you ask, and it can change | Yes, if you ask clearly | Free or paid plans | Ideas, grammar questions, better words |
| Grammar checkers | Yes | No | Grammar and spelling only | Free or paid | A final proofread |

Official IELTS materials: learn the standard
Start here, because this is where the rules come from.
-
ielts.org
Free sample questions, the public band descriptors that examiners use, and sample answers with examiner comments.
-
Cambridge IELTS books
Real past test papers. Many of the Writing answers in them come with a band and an examiner's comment.
-
The British Council and IDP
Both have free practice material on their websites.
These show you what a Band 6 or a Band 7 answer looks like. What they do not do is read your own essay and tell you what to fix. Use them to learn the target, then use a checker or a teacher to measure your own writing against it.
One warning: IELTS Progress Check, the official online practice test graded by IELTS markers, closed in June 2024. If a guide still recommends it, that guide is out of date.
ChatGPT: great for learning, weak for a band
ChatGPT is a very good study partner. It can give you ideas for an essay, explain a grammar rule, suggest a better word, or tell you if a sentence sounds natural.
It is weaker when you want a band you can trust:
-
The band depends on how you ask
Paste the same essay into two new chats and you may get two different bands.
-
It does not know the task unless you tell it
A Task 1 chart report needs different feedback from a Task 2 essay.
-
It has no built-in record of your IELTS progress
You have to track your bands yourself.
If you use it for feedback, give it the task question and ask for a band for each of the four criteria, with a reason that quotes your own sentences. The answer becomes much more useful, even though the number is still only an estimate.
Grammar checkers: good for the final proofread
A grammar checker finds spelling mistakes, missing articles and wrong verb forms. That is useful, especially at the end.
But it does not know what the question asked. It cannot tell you if you answered it, if your paragraphs are well organized, or what band your essay is. An essay with no grammar mistakes can still get a low band if it does not answer the question.
IELTS writing checkers: built for regular practice
An IELTS writing checker is made for one job: marking an IELTS answer against the four criteria. It is the best option when you want feedback after every practice essay without paying each time.
They are not all equal, so judge the result, not the website. Here is the difference between a result you can use and one you cannot:
| A weak result | A useful result | Why it matters |
|---|---|---|
| Your band: 6.5 | Task Response 7, Coherence and Cohesion 6, Lexical Resource 6, Grammatical Range and Accuracy 7 | Four bands show your weakest area. One number does not. |
| Lexical Resource: 6 | Lexical Resource: 6. You use "important" five times, and "make a research" should be "do research". | A reason that quotes your sentences tells you what to change. |
| 12 mistakes found | 5 article mistakes, 4 preposition mistakes, 3 verb tense mistakes | The same mistake five times is a habit, and you can fix a habit. |
| Your Writing band: 6.5 (after one Task 2 essay) | Your Task 2 band: 6.5 | Your Writing band combines both tasks, and Task 2 counts twice as much as Task 1. |
Two more things to check before you choose:
-
Accuracy claims
If a website says it is as accurate as a real examiner, ask who tested it, on how many essays, and how close counts as close. Even two trained examiners can give the same essay slightly different bands.
-
What "free" includes
Check how many essays you can check for free, if you need a credit card, if you get the full feedback or only a score, and if your essays are saved so you can see your progress.
VoyaLang, our own tool, is one of these checkers. You can see how it compares at the end of this guide.
A teacher: the most careful check, at the right time
A good IELTS teacher gives the most careful feedback. They notice things a tool can miss, like whether your ideas are really convincing. The cost is money and time, so most students cannot get a teacher's review on every practice essay.
A good plan is to practice often with a checker, and ask a teacher to review your writing at key moments, like a full mock test a few weeks before your exam.
Why do two checkers give you different bands?
Because they do not all read your essay the same way. Some look mostly at grammar. Some cannot tell a Task 1 report from a Task 2 essay. Some give one number and nothing else. So when two tools disagree, do not just believe the higher band. Compare the reasons they give, and trust the one whose reasons match your essay.
What no checker can do
-
Tell you your exact exam band
Every tool gives an estimate. Only the real test gives an official score.
-
Replace a trained examiner
An examiner can judge things a tool can miss.
-
Improve your writing for you
You improve when you fix your mistakes and write the next essay.
How to use a free checker to really improve
-
Write under exam conditions
About 20 minutes for Task 1 and 40 minutes for Task 2, with no help.
-
Read your lowest criterion first
That is where the biggest gain is.
-
Fix the mistakes that repeat
A mistake that appears five times matters more than one that appears once.
-
Write a new essay on a similar question
Do not rewrite the same essay until the number goes up.
-
Watch your bands over several essays
One score can be a little high or low. Five essays show you the real picture.
Test any checker in 15 minutes
-
Take an essay a teacher already marked
Now you have a real score to compare with.
-
Check it in the tool
Look at the four criterion bands, not only the overall band.
-
Compare the reasons
Do they match what your teacher told you?
-
Fix the mistakes and check again
Those mistakes should be gone, and the reasons should still make sense.

Frequently asked questions
Are AI IELTS writing checkers accurate?
They give an estimate, not an official score. A good one is close enough to guide your practice, but it can be wrong on some essays. Look for a tool that explains how it was tested and what it cannot do.
Can ChatGPT check my IELTS writing?
Yes, it can give useful feedback, especially on grammar and ideas. Its band is less reliable, because it changes with how you ask. For a band, ask for each of the four criteria with reasons, and treat the number as an estimate.
Is IELTS Progress Check still available?
No. The official IELTS Progress Check service closed in June 2024.
Is there a free IELTS writing checker?
Yes. Several IELTS writing checkers have a free version. Check how many essays it covers, if you need a card, and if you get the full feedback or only a score.
Can a checker tell me my real exam band?
No. A checker tells you where your writing is today and what is holding it back. Only the real IELTS test gives you an official band.
The bottom line
Use official materials to learn what each band looks like. Use ChatGPT to learn and to get ideas. Use a grammar checker for the final proofread. Use an IELTS writing checker for regular practice, and a teacher for the big moments. Whichever tool you choose, pick the one that shows you what to fix next.
About VoyaLang
VoyaLang is our own tool, so read this part knowing that.
We built VoyaLang to pass the checklist above. You get a band for each of the four criteria with the reason behind it, every correction named by type, feedback made for the task you wrote, and a rewrite at your target band. Your essays stay in your account, so you can watch your progress. We also explain how our scoring was built and what it does not claim.
The first difference you will notice is the screen. ChatGPT answers in a chat, so your feedback arrives as one long message you have to read through and match to your essay yourself. Official materials are pages of sample answers. VoyaLang puts it all on one screen: your essay with each correction marked in place, a band for each criterion, and a better version to compare with yours.
| What you get | ChatGPT | Official sample answers | VoyaLang |
|---|---|---|---|
| Your own essay marked | Yes, as a chat reply | No | Yes, on one screen |
| Corrections shown inside your essay | No, you compare it yourself | No | Yes |
| A band for each criterion | Only if you ask | Only for the samples | Yes |
| A timer for real exam conditions | No | No | Yes |
| Practice questions ready to use | You have to ask for one | A few tests per book | 1,400+ topics, including Task 1 charts |
| Your bands saved over time | No built-in progress view | No | Yes, with progress charts |
