Tonai is the practice companion that helps musicians master the hardest skill of all: playing in tune. Built for every musician who controls their own pitch — string, woodwind and brass players, and singers. Just play. Tonai listens, maps every note, and shows you exactly where your intonation drifts — then helps you fix it. THE TUNING SESSION The heart of Tonai. Play freely for two or three minutes — a melody, a passage, anything — and the instant you stop you get a full report: every note laid out on a stave, coloured by how well you tuned it, with the exact deviation in cents. No upload, no waiting; the analysis runs right on your device. Then get personalized AI feedback on each session, like having a teacher listen in. YOUR AI COACH Tonai learns from every session and turns it into a clear plan: • A daily practice focus • The notes and positions that keep slipping • Proof of how much you've improved • Streaks and milestones to keep you going WATCH YOUR TUNING IMPROVE For the first time, you can actually see your intonation getting better. Track your average cents off, your most-improved scales, weekly practice hours and streaks — a clear, honest picture of your progress. EVERYTHING YOU NEED TO PLAY IN TUNE • Tuning Sessions with instant, note-by-note intonation reports • AI coaching tailored to your playing • Scale practice with live pitch feedback, in any key and clef • A chromatic tuner for warm-ups (the time counts toward your stats) • A sample-accurate metronome that never drifts • Configurable reference pitch (A=442 by default) BUILT FOR YOUR INSTRUMENT For musicians whose intonation is in their hands — violin, viola, cello and double bass; flute, clarinet, oboe, saxophone and bassoon; trumpet, horn, trombone and tuba; and voice. If you control your own pitch, Tonai is for you. PRIVATE BY DEFAULT No login, no account. Your microphone audio is analysed in real time on your device and is never recorded, stored or sent anywhere. Your practice history stays on your phone. When you ask for AI feedback, only the numbers describing your intonation travel — never audio.
