I built a local-first bookmark cleaner

Hey IH, sharing a project I just shipped: Bookmark Cleaner (bookmarkcleaner.com).
The problem it solves: bookmarks accumulate for years and no one ever cleans them. Existing tools either upload your data or push you to delete things in bulk without review.
My approach:
• 100% local processing — you export bookmarks.html and every byte is analyzed in your browser. The server never sees a single bookmark.
• Review-first workflow — you make per-item decisions, a backup is created before anything changes, and nothing is deleted automatically.
• Chrome extension version for working with your live bookmark tree (read-only until you explicitly grant bookmarks permission).
Monetization: $9.99 one-time for Pro (saved decisions, domain review, bulk tools, extension-only Link Health). No subscription.
For the IH community: I'm giving away 100 Founder licenses for free while the project is new. Redeem at bookmarkcleaner.com/pricing:
