Bookmark Brain

Bookmark Brain keeps your bookmarks tidy, duplicate-free, and searchable using Chrome's built-in on-device AI. No internet connection is required, no account is needed, and your data never leaves your device. ORGANIZE WITH AI Bookmark Brain analyses your unorganised bookmarks and groups them into named folders automatically. It recognises categories like Development, Entertainment, Finance, AI Tools, Cloud Services, Shopping, Travel, News, and more. Before any changes are made, you review the proposed structure and confirm. A backup is saved automatically so you can undo with one click. FIND DUPLICATES Instantly scan your entire bookmark library for URLs saved more than once. Select which copies to remove and clean up in one click. CHECK DEAD LINKS Find bookmarks that no longer work. Bookmark Brain checks each URL and flags ones that are unreachable or returning errors, then lets you remove them in bulk. AI SEARCH Search your bookmarks by topic or meaning, not just exact words. Type what you are looking for and the on-device AI returns the most relevant results from your library.
