Never save the same link twice
Save a URL you already have, and onBookmarks shows you the existing bookmark on the spot — where it lives, when you saved it — before a duplicate is ever created.
Three layers of duplicate defense
Duplicates are caught when you save, when you import, and even the ones that are already in your library.
While you save
Paste a URL you've saved before and the existing bookmark appears right in the form — with its collections — so you can jump to it instead of duplicating it.
During bulk imports
Drop in a list of links or import a bookmarks file — anything you already have is flagged "already exists" and skipped automatically.
Across your whole library
Years of accumulated duplicates? The built-in library cleanup scans everything, finds duplicates and dead links, and helps you clear them in one pass.
Why duplicate detection matters
A duplicate isn't just clutter — it splits your own history.
One source of truth per link
Notes, tags, and reading history stay on one bookmark instead of scattering across copies.
Search results you can trust
No more guessing which of the three copies is the one with your notes on it.
Need it in two places? Use collections
One bookmark can live in multiple collections — the right way to file something twice without copying it.
Caught before it happens
The best duplicate cleanup is the one you never have to do.
Keep your library clean from day one
Import your existing bookmarks — duplicates get caught on the way in.
