Shubi AI is not a normal chatbot. It is a special system made only for IELTS writing. Real IELTS examiners helped design it, using official band descriptors, model essays and many real student answers from different topics.

Most tools give you just one band and some short, general comments. Shubi does much more. It marks your writing like a serious examiner: it gives separate scores for Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.

Then it does something very unique. For each of the four criteria, Shubi gives a band range (for example 5.0–5.5 or 6.5–7.0). This shows if you are at the bottom, middle or top of a band, not just "Band 6". So you can see clearly how close you are to your target score.

Shubi is also strict on purpose. It is designed to mark safely, not kindly. That means if Shubi says you are 6.5–7.0, a real examiner should not give you a lower score. Sometimes this feels tough, but it is honest. Soft, over-positive feedback feels nice for one day. Accurate, strict feedback helps you really move from 5.5 to 7.0.

Behind Shubi, humans are still important. Senior IELTS examiners showed Shubi what to look for in each part of your writing: how well you answer the question, how clear your paragraphs are, how strong your vocabulary is, and how accurate your grammar is. They used their experience to shape the AI and still check sample reports and add comments, so the system keeps improving and stays close to real exam standards.

For you, this gives three big benefits. First, the scores are trustworthy. If Shubi gives you 5.5–6.0 for Coherence and Cohesion, it also tells you which parts of your structure are weak and how to improve them. Second, the feedback is very specific. It shows better grammar and vocabulary inside your own sentences, not just in a separate list. Third, the next steps are easy to see. You know which of the four criteria is your lowest, how far it is from your goal band, and exactly what to change in your next essay.

Shubi AI is new, strict and sometimes challenging. But this is why it works. If you want to stop guessing, stop using simple AI that does not understand IELTS, and finally see what examiners really want, Shubi is here to help: smart AI plus real examiner experience, focused only on one goal—helping you reach your IELTS writing score as quickly as possible, at a price that normal students can afford.
