Is the AI Coach actually as accurate as a real teacher?
The AI grades against the same Cambridge Band Descriptors a real examiner uses, in under 4 seconds, via gpt-4o-mini + Whisper-1. In our internal testing it agrees with a human IELTS examiner within ±0.5 band 92% of the time — and it never has an off day. If you ever disagree, you can request a free 'examiner re-rate' from a human teacher.
Why pay for this when I can just use ChatGPT for free?
Do I have to commit long-term?
Will the AI judge me? I get anxious speaking English.
