Frequently Asked Questions
Is my recording uploaded?
No. The small AI model comes from this site and everything runs on your own device.
Which AI model does it use?
Basic Pitch by Spotify, an open-source model for finding notes.
Why are there wrong notes?
It is an estimate. A full song with drums and many instruments gives many wrong notes, so separate the part you want first or use a single instrument.
Why does it not open on my phone?
The heavier tools on this site are for a PC or laptop, so this one opens only there.
