I spend much of my free time reading often dense texts spanning the fields of History, Philosophy, Biomedical Research, and Finance/Investing. I use LLMs to help me understand what I'm reading and synthesize information across disparate sources. Existing tools are incredible, but as a Software Engineer, I found myself wanting to have the latest most powerful search techniques and agents available right while I'm reading in the same app. I created Biblion so that writers, students, academics, and serious amateur readers like myself could benefit from the latest LLM tools tailored specifically for reading and research in a single integrated experience. Biblion allows you to go deep on discrete passages while you're reading and synthesize understanding across thousands of documents across your library.

I've been using Biblion for the last few weeks and it allows me to do things that just aren't possible with ChatGPT, Claude, or Gemini. The main AI apps work for getting summaries of small PDFs, but I've been going through 300+ page PDFs for a course I'm taking and Biblion is the perfect tool for this kind of dense reading. It helps me keep track of what I've already read and analyze passages while I'm reading, but the feature that is the most innovative and helpful is the advanced search. This tool is able to find patterns and search across several documents in ways that would take me forever to do on my own. If you are working with large documents or books give it a try!
This is exactly what I've been looking for. I have hundreds of PDFs and EPUBs scattered across my Mac and actually being able to search by meaning rather than just keywords is a game-changer. The fact that everything stays local is a big plus too—I don't want my research notes sitting on someone else's server.
