FAQ
Good questions,
clear answers.
Is my camera video uploaded?
No. Hand tracking runs locally inside your browser. Camera frames are not sent to our server.
Which browser works best?
A current version of Chrome or Edge on desktop gives the most consistent performance. Safari and Firefox may also work, depending on the device.
Why can’t it see my hand?
Use even front lighting, keep your whole hand in the frame, separate your fingers clearly and avoid placing both hands over each other.
Do I need to know music theory?
No. Every gesture is mapped to a chord in the selected key, so the notes stay musical automatically.
Why do I need to click before sound starts?
Browsers require a clear user action before they allow audio and camera access. The start button unlocks both safely.
