Tried it on 3 random videos I watched, and the results were... mostly good, albeit mixed. On the one hand, it got my video about a Mario & Luigi: Brothership glitch dead right, immediately listing where you'd need to die to get an item early and what you'd get out of it. It also did an okay job summarising a Zelda dungeon analysis video by someone I'm subscribed to, with some info on why that dungeon was well-designed that clearly came from the video. Unfortunately, it did a poor job at summarising a video about plagiarism in the YouTube speedrunning essay space, associating the problem with smaller creators rather than the person the video was about and leaving out far too many details to be useful. This seems to confirm my assumptions about how an AI summariser would work in general; if the original media is a straightforward piece about one easily understandable topic, then it'll do fine and work about as well as a human would. If it's a longer piece with multiple points backed by various examples, then it'll struggle to summarise it in a way that makes sense.
