Consensus (consensus.app) is an AI-powered academic search engine that searches, synthesises, and explains peer-reviewed scientific research in plain language — with every answer grounded in citations from actual published papers rather than generated from general web content. Designed for researchers, clinicians, students, and evidence-curious professionals, Consensus addresses a fundamental limitation of general-purpose AI chatbots: the tendency to hallucinate or present uncited claims as fact. On Consensus, every AI-generated insight links back to the specific peer-reviewed studies it draws from, giving users a verifiable, evidence-based foundation for their questions. The platform offers a permanently free plan that includes basic paper search, 15 Pro messages per month with dynamic AI-powered search and analysis, and up to 3 Deep reviews per month — comprehensive literature syntheses covering many studies simultaneously — making it genuinely useful without a subscription.
Consensus structures its paid tiers around the depth and volume of AI research assistance. The Pro plan removes the monthly cap on AI-powered messages, scales Deep reviews to 15 per month, and unlocks unlimited access to every research tool on the platform — including search, analysis, citation graph, and more — making it suitable for students, researchers, and professionals who query scientific literature regularly. The Deep plan is designed for researchers and clinicians conducting frequent literature reviews, scaling Deep reviews to 200 per month alongside unlimited Pro messages and the full research tool suite. Team and Enterprise plans are also available for institutional use.
How Consensus Works
Users type a research question in natural language — "Does intermittent fasting improve metabolic health?" or "What does the evidence say about cognitive behavioural therapy for insomnia?" — and Consensus searches its database of peer-reviewed papers, identifies the most relevant studies, and produces a synthesised answer with inline citations to the specific papers it references. Each cited paper links to its abstract or full text where available. The Deep review feature conducts a more comprehensive and thorough literature synthesis across many studies simultaneously, suitable for researchers beginning a systematic review or clinicians evaluating the evidence base for a treatment decision. The citation graph and other research tools extend the platform's utility beyond question-answering into broader literature exploration and analysis.

Who Should Use Consensus?
Consensus is built for anyone who needs reliable, evidence-based answers grounded in peer-reviewed science rather than general AI-generated text. Students researching academic papers, healthcare professionals evaluating clinical evidence, scientists reviewing literature before a study, policy analysts assessing research bases, and curious individuals who want trustworthy scientific answers will all find Consensus more reliable than asking a general-purpose AI. The free plan is a meaningful starting point for occasional use. Pro suits regular users who need unlimited AI-powered queries and a higher Deep review allowance. The Deep plan is purpose-built for researchers and clinicians who conduct literature reviews as a core part of their daily work and need 200 comprehensive syntheses per month. Teams and institutions should enquire about the Team and Enterprise plans for shared access.
Frequently Asked Questions
What is Consensus?
Consensus is an AI search engine for peer-reviewed scientific research that delivers cited, evidence-based answers grounded in published academic papers. It synthesises findings from multiple studies in response to natural language questions and provides inline citations to the specific papers referenced. A free plan is available that includes basic paper search, 15 AI-powered Pro messages, and up to 3 Deep literature reviews per month.
Is Consensus free?
Yes. Consensus offers a permanently free plan that includes basic paper search, 15 Pro messages per month with dynamic AI-powered search and analysis, and up to 3 Deep reviews per month — comprehensive literature syntheses covering many studies simultaneously. There is no time limit on the free plan. Paid plans start at $15/month for unlimited Pro messages and 15 Deep reviews.
What is a Deep review in Consensus?
A Deep review is Consensus's most comprehensive form of literature synthesis — a thorough analysis drawing from many studies simultaneously to produce an in-depth, multi-paper summary of the research on a topic. It goes beyond what a standard Pro message produces and is designed for researchers and clinicians who need a rigorous overview of an evidence base rather than a quick answer to a specific question. Free users get up to 3 Deep reviews per month, Pro gets 15, and Deep plan users get 200.
How is Consensus different from ChatGPT or Perplexity?
Consensus focuses exclusively on peer-reviewed scientific research and grounds every AI-generated answer in citations from published academic papers. General-purpose AI tools like ChatGPT may draw from a broader range of sources — including non-peer-reviewed content — and can produce uncited claims. Consensus is specifically built for evidence-based research queries where verifiable citations and academic accuracy are the priority.
What research tools are included on the Pro and Deep plans?
Pro and Deep plans include unlimited access to all research tools on the Consensus platform — including the paper search engine, AI-powered analysis, citation graph (which maps citation relationships between papers), and additional tools. The free plan provides access to basic paper search and a limited monthly allocation of Pro messages and Deep reviews, without unlimited tool access.
