Kaplan IELTS is a structured prep platform, lessons, practice tests, and study schedules. BAND9AI is criterion-level AI scoring and reality checks on your own Writing and Speaking output. They solve different problems: Kaplan teaches format and builds volume; BAND9AI diagnoses which band descriptor leaks on your timed work. Many students need both, a course for foundation, calibrated AI before paying another exam fee.
Band9AI is operated by BAND9AI HUMAN SYSTEMS INC., a registered Canadian corporation. Trust & verification

Two different product models
Kaplan optimizes curriculum completion and test familiarity. BAND9AI optimizes rubric diagnosis. Neither replaces the other when your gap is undiagnosed Task Response or false Speaking confidence.
When to choose which
| Your situation | Better primary tool |
|---|---|
| New to IELTS format | Kaplan (or similar course) |
| Stuck at 6–6.5 with study hours logged | BAND9AI criterion checks |
| AI says 7, official mocks say 6 | Calibration-first AI |
| Need Listening/Reading strategy only | Course question banks |
