When you take a note while watching a YouTube video, MarkStamp records the exact playback time. Later, you can go straight back to that moment instead of scrubbing around to find it again.

★ One click adds a note at the moment you're watching

★ Click a note to replay the video from that point

★ Export your notes as Markdown with clickable timestamp links, ready to paste into Obsidian or any editor

★ Search notes across all your videos from a single page

★ Back up to JSON anytime. You can export your data whenever you want
