Consensus

Consensus is an AI-powered academic search engine that helps you find answers to research questions directly from peer-reviewed scientific papers — instead of a list of links, you ask a question and Consensus surfaces evidence-based findings from real studies, with citations, so you get what the science actually says. It's built for researchers, students, healthcare professionals and curious minds who want credible, source-backed answers rather than opinions or unsourced AI claims.

You ask a question like "does intermittent fasting improve longevity?" and Consensus searches 200+ million scientific papers, extracts and summarizes relevant findings, and shows a "consensus meter" indicating how much the research agrees — all linked to the source studies. It combines the accessibility of AI with the credibility of peer-reviewed research, and offers features like study summaries, quality indicators, and GPT-powered synthesis of findings.

Consensus offers a free tier (with limited searches/features), and paid plans (Premium, Enterprise) adding unlimited searches, advanced AI features and more.

Strengths: evidence-based answers grounded in peer-reviewed research, the consensus meter for gauging scientific agreement, direct citations, and huge paper coverage. Weaknesses: it's limited to what's in published research (not all questions have studies), summaries should be verified against source papers for nuance, and the best features need paid tiers.

For researchers, students, healthcare and science professionals, and anyone who wants answers backed by actual studies rather than unsourced claims, Consensus is one of the most valuable AI research tools — bridging AI convenience with scientific credibility, and especially useful for evidence-based questions in health, science and social science where knowing what the research consensus says matters.
