We’re building an MCP that lets you chat with long PDFs (e.g. textbooks with hundreds of pages) on platforms like Claude, Cursor, and other AI agents — without worrying about context limits.

Interesting, is this based on an external Vector DB to store and process the PDF?

Thanks for the great question! We actually use a reasoning-based, vectorless approach. In short, it follows this process:

  1. Generate a table of contents (ToC) for the document.

  2. Read the ToC to select a relevant section.

  3. Extract relevant information from the selected section.

  4. If enough information has been gathered, provide the answer; otherwise, return to step 2.

We believe this approach closely mimics how a human would navigate and read long PDFs.
