The mess
IELTS speaking practice needs a human examiner — expensive, scarce, and impossible to book at 2am the week before your test.
The system
Whisper listens, Mistral grades against the real band rubric, ElevenLabs answers back. A full speaking mock exam — questions, follow-ups, score and feedback — running in the browser.
The result
The judges ran a live mock exam on stage. It scored it, explained the score, and won the hackathon.
Graded band score in one session
Practice any time, no examiner needed
