Why We Built This
Scrubbing back to that one moment, every time
Browser bookmarks save a video, not a moment. If the point you cared about was eleven minutes in, you save the URL and then hunt for it again on every rewatch. InVideoMark saves the timestamp itself, so a bookmark drops you exactly where you left off — and a clip marks a start and end so the video pauses on its own at the end of the segment.
One click or Alt+B captures the exact timestamp on any YouTube or YouTube Kids video, with no break in what you're watching.
Mark a start and an end to make a clip. Play it back later and the video stops itself at the end point.
Bookmarks live on your device. No account required — export to JSON or back up to iCloud when you want a copy.
