String AI vs String AI

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. No ads or cross-app tracking. PLANS Start with a 7-day free trial with Basic lesson-time limits. All plans offer the same features; lesson time differs. • Basic — 15 min/day baseline · 450 min/month • Casual — 30 min/day baseline · 900 min/month • Standard — 45 min/day baseline · 1,350 min/month Within your monthly total, use up to three times your daily baseline on a day. Unused minutes expire at the monthly reset. Practice Room and class time do not count toward lesson limits. Subscriptions renew automatically. Manage or cancel in your App Store subscription settings.

Practice like a teacher is listening. Your first three analyses are free — no account, no card, nothing to set up. StringAI records your playing, measures what you actually did, and turns it into clear coaching — one thing to work on at a time. No vague encouragement, no guesswork: every note is measured, and every piece of advice points at something real in your recording. WHAT IT MEASURES • Intonation — how close each note lands to the pitch you meant, and how steady you hold it once you get there • Tone — brightness, stability, and the scratch, whistle, and surface-noise faults that come from bow speed, weight, and contact point • Bowing — bow angle and travel, straightness through the stroke, and how much of the bow you actually use • Rhythm — timing against the beat, note by note • Posture — bow hold and left-hand wrist angle, tracked with on-device vision HOW A SESSION WORKS 1. Record. Point your phone at yourself and play — a scale, an exercise, or a piece you're working on. Or record audio only, with no camera at all. 2. Get measured. Pitch, tone, bow motion, and posture are analyzed right on your device in seconds. 3. See what happened. Not a grade out of ten — real counts. How many notes landed in tune, which ones keep drifting and how often, and what went well. 4. Practice it. Guided practice blocks turn the diagnosis into something you can actually do, then check whether it worked. BUILT TO SHOW PROGRESS Every session counts the same things, so your trends mean something over weeks and months. Watch your out-of-tune notes fall, see which notes keep catching you out, compare attempts at the same passage, pin the piece you're working on, and set a weekly goal you can actually keep. YOUR RECORDINGS STAY ON YOUR DEVICE Practice video and audio are analyzed on your phone. Raw recordings are never uploaded to our servers. What syncs is your results and progress — not the footage. FOR WHO Adult beginners, returning players, students between lessons, and anyone practicing without a teacher in the room. Violin first — the measurement work is built on the violin's range and technique. A NOTE ON WHAT THIS IS NOT StringAI is a practice tool, not a teacher and not a medical or diagnostic product. Its measurements and AI feedback can be wrong. Treat them as a second opinion on your own ears, not a verdict.
