I created Sidenote for myself, to write summaries of conference talks and content-rich videos, so I could easily jump back to the moment of the video that’s referred in my notes. Sidenote is free to use, you can browse others' notes and create your own!
@0xval Technically yes, I could include the YouTube comments via their API, but generally the comment section doesn't have a lot of good quality content, so I'm keeping that out for now. As for related videos, I could also add them too, but then there would be no guarantee that those related videos also have notes, so not sure that would be a good user experience. Now about the tech stack, it's Node.js + Express + Angular + MongoDB, and it's closed source.
Hello, It looks interesting when you do it for yourself, it's probably the best effort. Develop, I believe that the education market is growing quite steeply.
