Ergo Chat is a browser extension that turns your PDFs and web pages into an interactive library you can chat with. Instead of manually searching through dozens of files, you ask questions and get answers based on your own materials.

Build a knowledge base from the sources you choose, and keep the conversation grounded in verified content.
- Upload and connect an unlimited number of PDFs
- Add websites and specific web pages to your library

Compare many sources at once
Ergo Chat can read and cross-reference dozens of documents and pages simultaneously, then return a consolidated answer.
- Useful for business content like policies, reports, and internal knowledge bases
- Helpful for personal work such as studying, research, and project preparation
For teams and individuals
Ergo Chat fits teams that need fast access to information across large document collections, as well as individuals working with academic papers, course materials, or professional literature.
