# Consensus

> Consensus is an AI-powered academic search engine that lets anyone ask a research question in plain language and get answers drawn directly from peer-reviewed science. Instead of returning a list of blue links, it reads across more than 200 million papers, summarizes findings, and shows - via its signature Consensus Meter - how much the published literature agrees. Founded in 2021 by Eric Olson and Christian Salem, the company is building what it calls an AI operating system for researchers, used by millions of students, scientists, clinicians and curious people.
