Consensus

Consensus is an AI search engine built for science. Instead of searching the whole web, it searches over 200 million peer-reviewed papers and gives you a plain-language answer with citations to the actual studies. Its Consensus Meter shows whether the research agrees, disagrees, or is mixed on your question, and its Deep review feature writes a structured literature review from the papers it finds.

Key Features

• AI answers from 200M+ peer-reviewed papers
• Consensus Meter shows whether studies agree or disagree
• Deep reviews: structured literature reviews from papers
• Study Snapshots summarise individual papers
• Citations linked to the original research
• API and MCP access for research workflows

How it works

The tool is made for evidence-based work: students writing papers, researchers doing literature reviews, clinicians checking what the evidence says, and policy makers who need trustworthy sources. Every claim in an answer links back to a paper, so you can verify it yourself instead of trusting a chatbot's word.

The free plan includes unlimited paper searches, 10 Pro messages a month, and 3 Deep reviews a month — enough to test it properly. Pro is $12 per month on annual billing ($144 a year) or $20 month to month, with unlimited Pro messages and 15 Deep reviews a month. Deep is $45 per month on annual billing for heavy researchers. Students get a 40% discount with a verified student email.
