What Librarian is

Librarian is a browser extension powered by lightweight retrieval augmented generation and AI. It helps you manage and query a personal knowledge base without sending everything to a remote service. You can import documents in formats like PDF and Word, scrape web content, and pull in browser bookmarks. Once your material is loaded, you can search it with semantic search and keyword analysis, ask questions about the current page, and get AI analysis of documents. It also connects to tools such as Notion, Gmail, and Google Drive. The extension is currently free of charge.

What you can do with it

- Import PDFs, Word files, web pages, and bookmarks into one base

- Search with semantic and keyword methods

- Ask questions and get answers grounded in your own material

- Connect Notion, Gmail, and Google Drive to widen the base

Who it is for

- Students who need fast lookup across course materials

- Researchers who manage large sets of literature

- Professionals who keep work documents and links in one place

What to watch out for

The quality of answers depends on what you have imported, so a thin library gives thin results. Because it is free, features and availability can change with updates. Offline use and storage limits depend on your browser and setup, so very large libraries may need management. Treat generated answers as a helpful summary, and check the original source for anything important. Name and archive exported files consistently so you can find and reuse them, and keep a backup copy of key data. When quality matters, export a small draft first to confirm the result before producing the final file.
