Transcribin
Finds the slide changes in a lecture video and writes notes with one section per slide.
Paste a YouTube lecture link and Transcribin detects where each slide starts, pulls the captions, and builds a Word document where each slide's section holds what was said while it was up. An uploaded video gets a list of slide-change times.
