Common questions
Is my microphone recording uploaded?
No. Capture, resampling, transcription, engraving, and preview all run in this browser. The recording and score stay on this device.
Where is my melody processed?
The NotationAI transcription and score engines process the melody in this browser. You can review, play, and download the result before opening the editor.
Why did it miss notes or rhythms?
Automatic melody transcription is an editable starting point. Results improve with one voice, a quiet room, clear note changes, steady timing, and a recording between 2 and 30 seconds.
