Consensus
AI search engine for peer-reviewed research across 200M+ scientific papers
Consensus is an AI academic search engine that queries 200M+ peer-reviewed papers and synthesizes findings via a "Consensus Meter" showing yes/no/possibly across analyzed studies. The free tier includes unlimited paper searches plus 3 Deep Searches per month; Pro costs $10/mo (billed annually) or $15/mo monthly. Best for researchers, students, and clinicians who need evidence-backed answers fast without manual literature review.
What is Consensus?
Consensus is an AI-powered academic search engine built on a corpus of over 220 million peer-reviewed scientific papers. Unlike general-purpose AI chatbots that synthesize from training data, Consensus runs every query directly against its indexed literature using a hybrid of semantic search (vector embeddings) and keyword search (BM25), then surfaces the papers most relevant to your specific research question. Every claim it returns is tied to a citable source paper, not generated text.
The platform’s signature feature is the Consensus Meter: a visual indicator that aggregates findings from analyzed studies and shows a yes/no/possibly breakdown in seconds, reranked by citation count, study design quality, and journal reputation. Deeper features include Deep Search, which automates full search strategy execution across up to 1,000 papers per query, and Study Snapshots, which extract structured data — methods, outcomes, populations, sample sizes — from individual papers. Medical Mode (launched October 2025) restricts results to clinical guidelines and high-impact medical journals, while Scholar Agent coordinates multi-agent workflows for complex research tasks requiring planning, retrieval, reading, and synthesis in sequence.
Who is it for?
Consensus targets anyone who needs evidence-backed answers faster than manual literature search allows. The free tier is genuinely usable for occasional research needs without a subscription, while Pro suits regular users doing ongoing literature work. The Deep tier is designed for power users who run frequent systematic reviews or need Medical Mode access.
Specific user profiles:
- Academic researchers and PhD students running literature reviews for papers, theses, or grant applications — Deep Search reduces initial screening from days to minutes.
- Clinicians and healthcare professionals who need quick access to clinical evidence; Medical Mode filters to guideline-level sources, and a 25% NPI-verified discount reduces cost.
- Science journalists and fact-checkers who need to verify whether a claimed finding reflects broader scientific consensus, not a single outlier study.
- Instructors and librarians teaching evidence-based research skills — the Consensus Meter makes the aggregation of evidence legible to students unfamiliar with meta-analysis.
