This is so good! I've been looking for a tool that will simulate the "listen to the Spiderman movie 50x" experiment https://www.youtube.com/watch?v=eliB_y0fmSk and this site can do it!
Every video is transcribed to get much better transcripts than the closed captions. I filter on high quality transcripts, and afterwards a LLM selects only plausible segments for the exercises. This seems to work well for quality control and seems to be reliable enough for these short exercises.
Would love your thoughts!
