# Bookmark Lab > Bookmark Lab is an AI-powered bookmark manager for Chrome. The free tier cleans and organizes your library — dead-link removal, duplicate detection, empty-folder cleanup, zombie-bookmark detection, and a visual dashboard with a 0–100 health score. Pro ($9.9 one-time, lifetime) adds AI auto-categorization and smart tagging (OpenAI / Claude / Gemini / Qwen / Kimi / DeepSeek / custom endpoints, using your own API key). All bookmark processing happens locally in the extension; bookmarks are never sent to the developer's servers. ## Features - [AI Smart Organization (Pro)](https://mark.shutong.work/#pricing): AI analyzes each bookmark's title and URL to auto-assign tags and folders; custom folder rules supported. Requires Pro + your own AI provider API key. - [Deep Cleaning — The Shredder](https://mark.shutong.work/): one-click scan for dead links (404/500), duplicate bookmarks, and empty folders. You select and confirm before anything is deleted. - [Zombie Bookmark Detection](https://mark.shutong.work/): finds bookmarks unvisited for 180+ days (adjustable) so you can archive or remove them. - [Visual Dashboard](https://mark.shutong.work/): interactive charts plus a 0–100 bookmark health score (weighted: healthy ×1, zombie ×0.5, dead ×0). - [Privacy First](https://mark.shutong.work/faq.html): local-first processing; AI features only send bookmark titles + URLs to the AI provider you configured. No account needed for free features. ## Pricing - Free forever: dashboard (basic), quick link scan, Shredder cleanup, empty-folder cleanup, duplicate detection. - Pro — $9.9 one-time (lifetime license): AI smart classification, auto smart tagging, deep content scan, full analytics & insights, priority support. ## FAQ - [Frequently Asked Questions (EN)](https://mark.shutong.work/faq.html) - [常见问题 (中文)](https://mark.shutong.work/faq-zh.html) ## Install - [Chrome Web Store](https://chromewebstore.google.com/detail/bookmark-lab-ai-bookmark/fkpkfmghiammellemeaelkgbfogbmipa): free download, v1.3.3, 8 languages. ## Contact - Developer: 戴金海 - Email: mkmindone@gmail.com
