Thought of another idea - trying to keep the creative juices flowing!
Thinking about a curated summary site - upload a video - course, youtube lecture, meeting, whatever it is, and choose from a couple options of summaries (based on level of specificity/depth), and get the result the same day - a clean, beautifully written up summary of whatever it is. Imagine the impact on students who miss a class, people who can't make a meeting, etc. This would also offer just a full transcript option.
Good idea - there are existing products aimed at businesspeople that summarize books in this way. e.g. https://www.getabstract.com/en/
