AI INTONATION COACH
Tonai is the practice companion that helps musicians master the hardest skill of all: playing in tune. Built for everyone who shapes their own pitch: strings, woodwinds, brass and voice.
No account. Your audio never leaves your phone.
AI MUSIC ANALYSIS
The heart of Tonai. Tap the orb and play a melody, a passage, anything. The moment you stop, you get a full report: a score out of 100, every note on the staff colored by how well you tuned it, and the exact deviation in cents. Then your AI coach tells you, in plain words, the one thing to work on next. Like having a teacher listening in.
Any instrument
AI COACH
Just play. Tonai listens to every note, shows you exactly where your intonation drifts, and tells you what to fix next.
DAILY CHALLENGES
A scale and its arpeggio, new every day. Win bronze, silver or gold and climb through all 24 keys: the 12 majors, then the 12 melodic minors, in one, two or three octaves. After every attempt you get a short AI note on what went well and which note to watch.
LIVE TUNER
Play sax, clarinet, trumpet or horn? Tonai shows note names and staves as written on your part, or at concert pitch if you prefer. Soprano, alto, tenor and baritone sax are all supported, and keys are spelled the way you read them: Bb major, not A# major.
YOUR PROGRESS
Your score over time, your personal records, your practice streak and the full history of every key. A clear, honest picture of your progress.
Violin, viola, cello and double bass. Flute, piccolo, oboe, clarinet, bassoon and the whole saxophone family. Trumpet, horn, trombone, euphonium and tuba. And voice, from soprano to bass. If you shape your own pitch, Tonai is for you.
