I built ClipMargin: timestamped notes for any video

I kept watching videos to learn and then not being able to find that one part I needed later. I knew I saw it somewhere but couldn't remember which video or where.

I tried Notion, Google Docs, plain text files. The notes were always disconnected from the video.

Books have margins. You can write right next to what you're reading. Videos don't have that. So I built one.

ClipMargin is a Chrome extension that opens a panel next to the video. You type a note and the timestamp saves automatically. No pausing, no switching tabs. Later you search your notes and click to jump back to the exact moment.

What it does:

- Notes pinned to the exact timestamp automatically

- Pin to a single moment or capture a time range

- Search across all your notes from every video

- Click any note to jump back to the exact moment

- Markdown formatting

- Screenshot capture from the video

- Tags to organize your notes

Currently works on YouTube. More platforms coming.

Would love feedback from anyone who learns from videos.
