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. Researchers, journalists, doctors, and students use Consensus to quickly understand the state of evidence on any scientific question.
The free plan gives you unlimited paper search and 20 monthly Consensus Meter and AI summaries. Premium at $11.99/month (annual) unlocks unlimited Consensus Meters, AI summaries, and advanced filters. Consensus has over 1.5 million users globally including researchers at Harvard Medical School, Stanford, Mayo Clinic, and major pharmaceutical companies.
Who Made Consensus? The Provider Behind the Tool
Consensus is developed by Consensus NLP, Inc., a Boston, Massachusetts-based AI company founded in 2021 by Eric Olson (CEO) and Christian Salem (President). Both founders have backgrounds in product management at Meta and Wayfair respectively, before pivoting to academic AI search.
Consensus has raised $11.5 million in Series A funding from investors including Draper Associates and FundersClub. The company's mission is to make peer-reviewed research accessible to non-experts — democratizing access to scientific evidence so journalists, policymakers, and the general public can make better-informed decisions.

Why Use Consensus? The Real Benefits for Users
Consensus's biggest strength is its unique Consensus Meter feature. For any yes/no question ("Does intermittent fasting reduce weight?" or "Does CBD help anxiety?"), Consensus shows the percentage of papers that say Yes, No, or Maybe — giving you an instant overview of scientific consensus rather than just one cherry-picked study.
Quick takeaways are another time-saver. Each paper includes an AI-generated 1-sentence summary of its key finding — letting you scan 50 papers in 5 minutes instead of opening each abstract individually. For journalists fact-checking claims and doctors looking up evidence, this is genuinely transformative.
The natural language search is more intuitive than traditional academic search. Ask "Is the keto diet bad for the heart?" and Consensus understands the question's intent — returning papers that directly address it rather than just keyword matches.
