Consensus
AI search engine that synthesizes answers from 250M+ peer-reviewed papers with evidence-based consensus meters.
Overview
Consensus is an AI-powered academic search engine that answers research questions by synthesizing findings from over 250 million peer-reviewed scientific papers. Instead of returning a list of links, it reads papers, extracts relevant findings, and presents a direct answer backed by citations — think Perplexity, but exclusively for scientific literature.
The standout feature is the Consensus Meter, which shows at a glance how strongly the body of research supports or contradicts a given claim. Ask "Does creatine improve cognitive performance?" and you'll see a percentage breakdown of studies that say yes, no, or are mixed — something no other tool does this cleanly. It also generates structured study snapshots showing methodology, sample size, and key outcomes for each cited paper.
Consensus is built for researchers, students, healthcare professionals, and evidence-based practitioners who need fast, reliable literature review without wading through hundreds of abstracts. It's not trying to replace deep systematic reviews, but for quickly establishing what the evidence says on a topic, it's the fastest path from question to answer in academic AI.

Pros & cons
Pros
- ✓Consensus Meter gives instant visual evidence breakdown — unique among academic search tools
- ✓250M+ paper database with strong coverage across sciences and social sciences
- ✓Answers are always grounded in peer-reviewed literature with full citations
