I created a simple CLI that turns a YouTube guitar-lesson video into a PDF of the guitar tab.There are services that transcribe music from Youtube videos into tabs, but they never work well enough for me. Instead I'm taking a simpler approach. It downloads the video, samples frames, uses Claude vision to locate the tab region, crops every frame to that region, de-duplicates the crops by the bar number printed on each line of the score, and stitches the distinct tab lines vertically into a PDF.I didn't test it on a lot of different Youtube videos yet, so problem will arise for sure.

Could you build this?
Yes A CLI utility that uses yt-dlp to grab video, extracts frames via ffmpeg, sends them to Claude's vision API to recognize guitar tablature, and compiles images into a PDF is trivial to vibe-code.
