Consensus AI
Search and summarise peer-reviewed scientific evidence with AI instantly.
Consensus AI Review: AI Search Engine Built Exclusively for Scientific Evidence
Searching for scientific evidence is slow and requires expertise. You navigate databases, parse abstracts, assess methodology, and synthesise findings across multiple papers manually. Consensus AI makes this entire process dramatically faster by searching a corpus of over 200 million peer-reviewed research papers and returning direct, cited answers to scientific questions in seconds. For researchers, healthcare professionals, students, and evidence-hungry professionals in any field, it is the most efficient path from a question to a research-backed answer.
Quick Summary
Consensus AI is an AI-powered scientific research search engine that searches over 200 million peer-reviewed papers and returns summarised, cited answers to research questions, with a consensus meter showing how much scientific agreement exists on any topic.
Is it worth using? Yes for anyone who regularly needs to find and understand scientific evidence without spending hours manually searching academic databases. Who should use it? Researchers, healthcare professionals, students, science writers, and evidence-based practitioners in any field who need quick access to peer-reviewed findings. Who should avoid it? Users looking for general web search or AI chat unrelated to academic and scientific content.
Verdict Summary

Rating ⭐⭐⭐⭐½ 4.6 / 5
What Is Consensus AI?
Consensus AI is a scientific research search engine founded in 2021 by Eric Olson and Christian Salem. It indexes over 200 million peer-reviewed research papers from sources including PubMed, Semantic Scholar, and major academic publishers across medicine, biology, psychology, economics, computer science, and other disciplines. The platform uses AI to extract claims from papers, understand the direction of findings, and synthesise answers to research questions that show what the scientific evidence collectively says rather than just returning a list of papers to read manually.
Its Consensus Meter feature visually indicates the degree of scientific agreement on any searchable topic, showing at a glance whether a body of research is conclusive, mixed, or contested. This alone makes it more useful than a standard literature search for quickly gauging the state of evidence on a question.
How Consensus AI Works
- Enter your research question at consensus.app. Frame it as a research question rather than a keyword search for best results.
- AI searches the paper corpus. Consensus searches over 200 million peer-reviewed papers and identifies those most relevant to your specific question.
- Review the synthesised answer. Consensus AI produces a direct summary answer to your question citing the supporting papers, showing you the collective direction of research findings.
- Check the Consensus Meter. The visual meter indicates whether the evidence on your question is strongly supportive, mixed, or inconclusive across the retrieved papers.
- Examine individual papers. Click through to individual paper summaries showing the key findings, study design, and a link to the full paper for any citations you want to investigate further.
- Save and organise. Save searches and papers to your library for reference and building a research collection on a specific topic.

Frequently Asked Questions (FAQ)
Consensus AI is an AI-powered scientific research search engine that searches over 200 million peer-reviewed papers and returns synthesised, cited answers to research questions with a Consensus Meter showing scientific agreement levels.
Yes, Consensus AI offers a free plan with limited daily searches and basic features. The Premium plan at $9.99/month provides unlimited searches and GPT-4 powered synthesis.
Consensus AI indexes over 200 million peer-reviewed research papers from major academic databases including PubMed, Semantic Scholar, and leading academic publishers.
The Consensus Meter is a visual indicator showing the degree of scientific agreement across the retrieved papers for a given research question, ranging from strongly supportive to mixed to inconclusive based on the direction of findings across the result set.
Consensus AI provides AI-generated summaries of paper findings and links to the original papers. Full-text access depends on the paper’s availability and any journal paywalls at the source.
Google Scholar returns a list of papers matching keywords. Consensus AI synthesises a direct answer to your research question from the findings of relevant papers, shows the degree of scientific consensus, and extracts key study details without requiring you to read each paper individually.
