What is kOS?

kOS is an intelligent, researcher-first platform designed to transform how scholars, scientists, and knowledge workers build, interrogate, and evolve their personal PDF libraries. More than a document repository, kOS leverages responsible AI to turn static PDFs into dynamic, interconnected knowledge bases—empowering deeper insight, faster synthesis, and verifiable scholarly workflows.

How to use kOS?

Getting started with kOS is intuitive and secure: upload PDFs from your local machine, cloud storage (Google Drive, Dropbox, OneDrive), or public URLs. Once ingested, kOS automatically indexes content, extracts key concepts, and enables contextual search, AI-assisted summarization, and smart annotation. You can then generate live presentations that trace your research journey—from source material to insight—and export or share authenticated, timestamped workspaces for peer review or collaboration.
