Quick start
- Open the extension's side panel and create a deck.
- On a supported video page, press Alt+M (or your configured shortcut) to bookmark the current moment.
- The timestamp and a screenshot of the frame are saved automatically. Click any bookmark to jump back to that second.
Frequently asked questions
Which sites are supported?
YouTube, Bilibili, Vimeo, Netflix, iQIYI, Tencent Video, Tudou, Youku, Instagram, X/Twitter, TikTok and Facebook. Other sites may work partially.
Do I need an account?
No. There is no account, no sign-up and no cloud sync. The extension works entirely offline.
Where is my data stored?
Locally in your browser (IndexedDB / localStorage). Nothing is uploaded. See the Privacy Policy.
How do I back up or move my data?
Open the extension's settings page and use Export to save a ZIP archive. The same page can re-import it later.
The shortcut does nothing on a video page
Click the video page first so it has focus, then press the shortcut. If the issue persists, open chrome://extensions/shortcuts and make sure the command is bound.
How do I delete everything?
Settings → Clear data. This removes all local bookmarks and decks and cannot be undone.
