About Chronomark
Chronomark keeps years of accumulated bookmarks organized without any risk to what you already have.
WHAT IT DOES
- Files bookmarks into Organized Bookmarks / <Year> / <Month> folders automatically, based on when each one was actually saved
- Watches for new bookmarks and shows a badge count — click to file them in, nothing happens silently
- Searches your entire bookmark collection by title or URL, filed or not, and shows you where each result currently lives
- Detects genuine duplicate bookmarks (the same URL saved more than once) across your whole collection and reports them
- Corrects bookmarks that land in the wrong Year/Month folder automatically
SAFE BY DEFAULT
Everything above only copies bookmarks — your existing Bookmarks Bar and folder structure are never touched unless you turn on one of two optional toggles:
- Delete originals after filing (off by default)
- Automatically clean up duplicates (off by default, resets itself after each run)
Both explain exactly what they'll do before you turn them on.
100% LOCAL
Chronomark never sends your bookmarks anywhere. Everything runs entirely on your device using Chrome's own bookmarks and storage APIs — no analytics, no external servers, no accounts.
