MarkSnap - Video & Audio Timestamp Bookmarks

Save timestamps with notes on YouTube, Udemy, Vimeo & podcasts in one keystroke. Timeline markers, free Markdown & Notion export.

Save any moment in a YouTube video, online course or podcast with one keystroke — and jump back to it in one click. MarkSnap turns timestamps into notes you can actually find again. Press Alt+B while something is playing, add a quick note, and a marker appears right on the player's timeline. Hover it to read your note, click it to jump straight back. No more scrubbing through a three-hour lecture to find that one explanation. 100% free: unlimited bookmarks, collections, export and sync are unlocked for everyone. 🎯 How it works 1.

It's built by one independent developer and kept going by people who choose to leave a tip on Ko-fi — entirely optional. 🔒 Privacy Your bookmarks and notes are stored in your browser and, if you use Chrome sync, in your own Google account. No sign-up is needed. MarkSnap does not read your browsing history or the content you watch, and only runs on the sites listed above. It sends a few anonymous usage events (such as "popup opened") to learn which features are used — never your notes, bookmarks or the pages you visit.
