Everything your bookmarks need

One click. No manual sorting. No sign-up required.

AI Categorization

Stash reads every title, URL, and meta description, then builds a clean folder structure tailored to your actual collection — not generic templates.

Duplicate Detection

Spots duplicates even when URLs aren't identical — normalizing tracking parameters, www prefixes, and trailing slashes so nothing slips through.

Dead Link Checker

Tests every bookmark for 404s, timeouts, and unreachable pages. Years of link rot, surfaced in one scan.

Redirect Detection

Flags bookmarks that silently redirect to a different domain. Old links get bought up by squatters, ad farms, and worse — Stash helps you catch them before your browser doesn't.

Interactive Report

Every category, duplicate, and broken link in one place. Rename folders, merge categories, and clean up problems without ever opening the bookmark manager.

Fully Private

Your API key never leaves your browser. Bookmark data is sent only to your chosen AI provider — never to our servers, never stored anywhere else.

How it works

3 easy steps.

1

Add your free AI key

Pick a free AI provider (we recommend Gemini) and paste your API key — it takes 30 seconds.

2

Click "Scan Bookmarks"

Stash checks every link, finds duplicates, and sends your bookmarks to AI for categorization — all automatically.

3

Review your report

See everything in one place: organized category folders, duplicate groups, dead links, and stale redirects. Clean up each with just a couple of clicks.
