Piano apps check your notes. Nobody checks your hands.
Song apps tell you whether you hit the right key. They can’t see a wrist that sinks a little lower every week, or shoulders that creep up in the hard bars. Those are the habits a teacher fixes first, and the ones Octave AI catches.

One piece. Three steps. Two minutes.
- 01
Prop up your phone
Off to one side and a little above the keys, so both hands are in frame. A music stand or a stack of books is fine.
- 02
Play one piece
Record right in your browser, or upload a video you already have. Anywhere from 10 seconds to 3 minutes, any song, any level.

Get your notes
A score, every moment that needs work with the exact fix, and a short drill for each of your top 3 priorities.
It catches what a teacher would.
Every video is checked for the three things a teacher watches: where your hands are, how you sit, and how you shape loud and soft.
Hand position
Fingers that collapse
Knuckles caving in as a finger lands, shown at the moment it happens.
Hand position
A tucked thumb in scales
The small hitch that caps how fast your runs can go.
Posture
Shoulders creeping up
Tension you can't feel while you're concentrating on the notes.
Dynamics
Everything at one volume
Checks whether your soft is really soft and your loud is really loud.
Dynamics
A melody drowned out by the left hand
Makes sure the tune sings over the accompaniment.
Here’s what you get back.
Not just a score. Every note points to a second of your video and tells you what happened, why it matters and how to fix it.
- A score out of 100, split into hand position, posture and dynamics
- Every moment that needs work, one tap from that second of your video
- What happened, why it matters and exactly how to fix it
- Your top 3 priorities, each with a short drill
- What you're already doing well, so you keep doing it
Example report
0:12
PositionHigh
Left wrist drops below the keys
- What happened
- In the arpeggio at 0:12 your left wrist sinks below the knuckle line.
- Why it matters
- A dropped wrist forces the fingers to pull up from underneath, which tires the forearm and blurs fast notes.
- The fix
- Keep the wrist level with your forearm, as if resting on a cushion of air.
Drill: Coin on the wrist
5 minPlay a C major scale at half tempo with a coin on the back of your left hand. If it slides off, your wrist dropped.
0:48
DynamicsMedium
Crescendo arrives all at once
- What happened
- The build-up at 0:48 stays quiet, then jumps to loud on the last bar.
- Why it matters
- A gradual crescendo creates tension and direction; a sudden jump sounds like a switch.
- The fix
- Map the crescendo across four bars and add a little weight on each.

Questions, answered.
How is this different from Simply Piano or Flowkey?
Those apps listen for the right notes. Octave AI watches how you play them: your hands, your posture and your touch. They work well together. Learn songs there, check your technique here.
Do I need any special equipment?
No. Any acoustic piano, digital piano or keyboard, and the camera on your phone or laptop.
How long should my video be?
Anywhere from 10 seconds to 3 minutes. One piece, or just the section you're working on, is perfect.
Is the first report really free?
Yes. The full report, and no card needed. After that, every video still shows your biggest issue for free.
How accurate is it?
Every note links to the second it happened, so you can watch it and judge for yourself. A phone mic can only measure loudness relative to the rest of your playing, and the report tells you that.
Will it replace my teacher?
No. Think of it as a coach between lessons. It catches habits early so your lessons go further. If you have a teacher, show them your reports.
What happens to my videos?
Raw uploads are deleted after 30 days and playback copies after 90. You can delete everything from your account at any time.
