Write & Improve builds general English writing with CEFR-level feedback from Cambridge; BAND9AI scores IELTS Writing against Task Response, Coherence, Lexical Resource, and Grammar on exam-style prompts. Write & Improve is excellent for writing habit and broad competence, it is not an IELTS band oracle. BAND9AI is built for students who need to know which IELTS descriptor caps their Task 2 at Band 6. Use both if you want volume plus rubric diagnosis.
