I built a Chrome extension to take timestamped notes while watching YouTube.
I learn a ton from YouTube, but taking notes with timestamps was always annoying so I built a simple extension for that.
It's just a simple extension (plain HTML, CSS, JS). Everything is stored locally in your browser — no account, no sync.
