String AI helps you practice violin, viola and cello with lesson plans, playing feedback and music classes. LESSONS AND 5-AXIS FEEDBACK Tune your instrument, choose a piece and practice the planned measures. After a take, check feedback on pitch, rhythm, dynamics, tone and posture, and work on selected passages in follow-up missions. Pitch appears on the tuner while you play; scoring and coaching follow the take. Results depend on what the microphone and camera can measure. MUSIC CLASSES — VIBRATO, EAR TRAINING, THEORY & MUSIC HISTORY Practice vibrato on your instrument. In ear training, theory and music history, work through explanations and questions, then revisit what you learned in unit checks. Your teacher can assign class lessons as homework. MY SCORES — YOUR PRINTED PART Bring in a printed single-instrument part from Files, Photos or the camera. The app reads it on your device; you can fix misread notes and markings, switch between the full score and the original, and split two pieces on one page into separate scores. Listen back and choose measures for a lesson. For student accounts. Your music, edits and results stay on this device. A connected teacher sees practice time and, with title sharing enabled, the title you enter and its instrument. They can assign that title as homework, but cannot see the music. PRACTICE TOOLS AND RECORDS Use the tuner and metronome in the Practice Room. Find scales, etudes and pieces in the library. Set a target date, follow your practice plan, and review practice days, scores and journal entries. WITH YOUR TEACHER (OPTIONAL) Connect through an invite code to share practice records, 5-axis scores, weak points, journal notes and mood, and homework progress. The full list is in our Privacy Policy. Teachers can assign pieces or class lessons, leave notes on your practice plan and mark library scores. With AI coaching on, lesson-start guidance also uses their notes. Under-14 sharing requires parental approval. You can disconnect at any time. Recordings are not shared with teachers. RECORDINGS Audio and video are processed on your device and are not uploaded to our servers. Lesson replays are temporary. Practice Room videos stay on the device until deleted in the app. Choosing Save video puts a copy in Photos, where your photo app settings apply. Account data is described in our Privacy Policy.
