I can’t possibly tell if this is worth it over leading class labeling tools in audacity. There is a sign up with no pricing and no mention of limits.

Why would i have a good impression if my first experience is a sunk-cost time-sink dark-pattern?

So disrespectful of your potential users time.

I haven't used Audacity lately but I don't know of any plugin or feature that transcribes music audio into abc notation.

		It's not super clear but I don't think it does automatic transcription for you; I think it just provides a text editor with syntax highlighting, and that it syncs the scrolling of the rendered output to (prerecorded) audio playback.

		Well if you transcribed to notation, then pitch clases is trivially easy. And not really useful?

Can you recommend labelling tools to use instead
