Practice like a teacher is
listening.
StringAI records your playing, measures intonation, tone, bowing, rhythm, and posture on your device, and turns it into clear, specific coaching — one thing to work on at a time.
On-device analysis
Your practice video and audio are analyzed on your phone. Raw recordings stay on your device — they are never uploaded to our servers.
Real measurements
Pitch, tone quality, bow motion, and posture are measured with signal processing and on-device vision — not guesswork.
Focused coaching
An AI coach reviews the findings and tells you the one or two things that matter most this session, with an exercise to fix them.
Track your progress
Every session is scored the same way, so your trend lines actually mean something over weeks and months.
