Cambly sells live English conversation minutes; BAND9AI scores IELTS Speaking against public band descriptors. Cambly tutors rarely run strict Part 2 timers or abstract Part 3 follow-ups with criterion notes. You may feel fluent after fifty hours of chat yet still score Band 6 when evaluated on idea development and pronunciation under exam pressure. Use Cambly for talk-time comfort; use rubric AI for mock scoring and leak diagnosis.
Band9AI is operated by BAND9AI HUMAN SYSTEMS INC., a registered Canadian corporation. Trust & verification

Recommended hybrid stack
- 2× weekly Cambly sessions for spontaneous talk (20 min).
- 1× weekly timed Part 2 + Part 3 recording scored by AI.
- Log one criterion fix per week (e.g. fewer fillers).
- Monthly human mock before booking: comparison anxiety check.
Part 2 timer discipline
Use phone timer for exactly two minutes. Cambly chats rarely enforce cue-card pacing.
Key takeaways
- Cambly builds comfort; it is not a full IELTS Speaking simulator.
- Exam Speaking needs timed Part 2 and evaluative Part 3 practice.
- BAND9AI adds repeatable rubric scoring between tutor sessions.
- Combine talk-time with criterion mocks before exam fees.
