Sidenote: a web app to take timestamped notes on YouTube videos

First time poster here. I just finished the MVP of my quarantine project, a web app to take notes with timestamps on YouTube videos, now online at https://sidenote.me

This is something I use for myself to create my own summaries of conference talks and content-rich videos, also so that I can easily jump back to the moment of the video that’s referred in my notes. Here is an example:

For now it’s just a little tool I built for myself, and I decided to open it up for others to create and share their notes as well if they find it useful.

Given that I'm not selling anything, I haven’t figure out yet how to grow a user base and even less how to monetize it. If anyone has ideas about that, please share.

Thanks for reading up until now, all feedback is welcome!
