About Mark One
Mark One makes Chrome bookmark folders collaborative.
Share a folder, invite someone by email, and keep bookmarks synced as they change. No exports, no manual copying, and no rebuilding the same folder structure on every browser.
Mark One works directly with Chrome bookmarks, so shared folders feel natural and stay easy to manage.
Perfect for:
- team resources
- client handoff links
- shared research folders
- household or personal multi-device bookmarks
- recurring project collections
What you can do:
- Share a bookmark folder by inviting someone by email
- Accept shared folder invites directly in the extension
- Sync bookmark and subfolder changes across browsers
- Add, edit, move, and remove bookmarks in shared folders
- Restore shared folders on another browser
- Manage members, pending invites, and rejected invites
- Stop sharing when access is no longer needed
How it works:
1. Pick a bookmark folder in Chrome
2. Invite someone to it
3. They accept the invite in Mark One
4. Both sides stay in sync automatically
Why people use Mark One:
- Works directly with Chrome bookmarks
- Fast sync between shared browsers
- Clean invite and member management
- Simple restore flow when using another browser or device
- Built for bookmark folders, not generic file sharing
Access model:
- Receiving shared folders is free
- Sharing your own folders starts a free trial, then requires a subscription
