Field notes
The homepage groups twelve named utilities into creator, musician, and multimedia sections. Listed workflows include exporting a beat-tempo map as MIDI, practicing a song in a slowed loop without changing pitch, and grading rhythm taps note by note. The maker says processing stays in the browser and files are not uploaded; that privacy description is a site claim, not independently tested here.
