String AI is an AI practice coach built exclusively for violin, viola, and cello. It listens to every note, watches your form, scores every attempt, and tells you exactly what to fix — in real time. Its scoring standards were designed and reviewed together by violin, viola, and cello teachers trained at Curtis, Colburn, Seoul National University, Eastman, Manhattan School of Music, USC, and CIM. The standard a world-class teacher holds you to, applied to every minute you practice. THE STRUCTURE OF A LESSON, EVERY TIME YOU PRACTICE String AI plans your session, scores each attempt across five axes, diagnoses what needs work, and prescribes drills that target it. You always know what to work on next — and why. GOOD PRACTICE HABITS, BUILT IN Set a target date for any piece and String AI paces you to it — planning each day's session, tracking whether you're ahead or behind, and warning you early if the timeline isn't realistic. Spots that need work aren't glossed over: the AI isolates them into short drills just a few measures long and has you repeat exactly those spots. This is how serious players practice — and the app makes it a habit. WHAT IT SCORES (5 AXES + SUPPORTING) • Intonation — real-time pitch tracking, note by note • Rhythm — timing and steadiness • Tone — clarity and quality of sound • Dynamics — control of loud and soft • Posture & bowing — on-device vision analysis of your form Supporting checks such as vibrato complete the picture, so your next priority is always clear. BUILT FOR STRINGS — NOT A GENERIC MUSIC APP Violin, viola, and cello each receive instrument-specific analysis, tuned to how the instrument is actually played. WORKS WITH YOUR TEACHER (OPTIONAL) Enter your teacher's invite code and the week between lessons stops being a blind spot. Your teacher sees your practice time, five-axis scores, weak points, and assignment progress — and can send back assignments, teaching notes that steer the AI coach toward what they want you working on, and markings written directly on your sheet music. Off by default, on only once you enter the code, and revocable at any time. Recordings are not shared with your teacher. YOUR SOUND NEVER LEAVES YOUR DEVICE Audio and video are processed on your device and are not uploaded to our servers. Lesson replays are temporary. Practice Room recordings are saved on this device when you stop recording and can be deleted in the app. Your account stores practice records and the limited data described in our Privacy Policy. No ads. No tracking across apps. PLANS Start with a 7-day free trial, then choose a plan by daily practice volume.

Terms of Use (EULA): https://youna-string.github.io/stringai-legal/terms-of-service.html Privacy Policy: https://youna-string.github.io/stringai-legal/privacy-policy.html For a fraction of the cost of a single private lesson, String AI coaches every practice session, every day. From beginners building intonation to advanced players refining tone — make every minute count. Students under 14 require a parent's consent before use, in line with children's privacy laws.
