Finds real duplicates
Smart URL matching folds http/https, www, trailing slashes, #fragments, and utm_ tracking params, so the same page saved five different ways shows up as one group you review and resolve.
Local bookmark cleanup · Project memory export · No subscription
Clean your bookmarks. Keep the memory.
Import your Chrome, Safari, or exported bookmarks, and Bookmark Memory Cleaner finds the duplicates and dead links — then exports the survivors as project memory for Obsidian, Markdown, or your coding agent. It runs entirely on your Mac and never touches your live browser data.

Why this exists
Years of bookmarks, none of the memory.
Bookmarks pile up across browsers and machines: the same link saved three times, pages that 404 now, folders no one has opened in years. Browsers help you save links but never help you make sense of them.
Bookmark Memory Cleaner reads your bookmarks locally, collapses the duplicates and dead links, and turns what is left into a structured memory you can actually use — a Markdown or Obsidian note, or context for a coding agent. The cleanup is reversible: it exports a fresh file, it never rewrites your browser.
Catches dead links
Optional, throttled link checking flags pages that no longer resolve and bookmarks gone stale — so your cleaned set is the links that still matter, not a graveyard.
Exports project memory
The reason it is here: turn survivors into Markdown, CSV, or an Obsidian note (frontmatter + source notes) you can feed Codex, Claude Code, or your own knowledge base.
Never destructive
It reads imported or exported files and writes a clean new export. Your live Chrome and Safari data is never modified, and a JSON backup is one click away.

Free to scan. $14.99 to keep.

FAQ
Which browsers does it support?
Chrome and other Chromium browsers (Brave, Edge, Arc) via their Bookmarks file, Safari via export, and any browser through the universal HTML bookmark export. You pick the file; nothing is read behind your back.
Does it change my actual browser bookmarks?
No. It reads an imported or exported file and writes a clean new export that you re-import if you want. Your live browser data is never modified, and you can keep a JSON backup.
Is anything sent to the cloud?
Cleanup runs entirely on your Mac. Optional dead-link checking makes throttled requests to the bookmarked sites to see if they still resolve; you can leave it off. License activation and update checks are the only other network features.
What is project-memory export?
It turns your cleaned bookmarks into a structured Markdown, CSV, or Obsidian note — with source links — so a folder of links becomes context you can hand to Codex, Claude Code, or your own knowledge base.
What is free and what is paid?
Import, scanning, duplicate review, dead-link detection, and JSON backup export are free. A license unlocks Apply Cleanup and project-memory export to Markdown, CSV, and Obsidian.
Is it a subscription?
No. Bookmark Memory Cleaner is $14.99 one-time for this major version, with a 14-day refund.
