What Is Consensus? The AI Search Engine That Finds Scientific Consensus in 2026
Consensus is an AI-powered scientific search engine that searches across 200+ million peer-reviewed papers and tells you what scientific research actually says about any question. Unlike Google Scholar (which returns lists of papers) or Elicit (focused on systematic reviews), Consensus is designed for quick, evidence-based answers — with a unique Consensus Meter showing the percentage of papers that support, oppose, or are neutral on any claim.
Consensus is particularly powerful for medical questions, nutrition research, public policy, and any topic where you want to know "what does the science actually say?" instead of relying on cherry-picked studies.
The free plan gives you unlimited paper search and 20 monthly Consensus Meter and AI summaries. Premium at $11.99/month unlocks unlimited Consensus Meters, AI summaries, and advanced filters.
