About Consensus
Consensus is an AI academic search engine that transforms how researchers access scientific literature. It searches over 220 million peer-reviewed papers and uses advanced language models combined with semantic search to deliver evidence-backed answers to research questions in seconds, not hours. Unlike general-purpose AI tools like ChatGPT, Consensus is purpose-built for scientific research, grounding every response in real academic sources with full citations. The platform employs a hybrid search approach combining AI embeddings with traditional keyword matching to understand user intent while maintaining precision, then re-ranks results by research quality using signals like citation counts, journal impact, and study methodology. Users can ask natural language questions like "Does X improve Y?" or conduct deep literature reviews across multiple papers, with features like the Consensus Meter showing scientific consensus on yes/no questions, Study Snapshots extracting key paper details, and Ask Paper allowing interactive engagement with full-text PDFs. Ideal for students, researchers, academics, healthcare professionals, and anyone seeking evidence-based information grounded in peer-reviewed science.

Frequently Asked Questions
How does Consensus differ from Google Scholar or ChatGPT?
Consensus is purpose-built for scientific research, not a general search engine or generative AI. Google Scholar returns links; ChatGPT may hallucinate. Consensus synthesizes evidence from peer-reviewed papers with citations, using AI only after retrieving relevant research. Every response is grounded in real academic sources.
What is the Consensus Meter and how does it work?
The Consensus Meter is a visual indicator showing scientific agreement on yes/no questions. When you ask 'Does X improve Y?', the tool scans relevant papers and categorizes findings as Yes, No, Possibly, or Mixed, displaying results as colored bars to show scientific consensus.
Can I use Consensus for free?
Yes. The free tier includes unlimited searches across 220M+ papers, plus 10 Pro Analyses, 10 Study Snapshots, and 10 Ask Paper messages per month. For unlimited premium features, upgrade to Pro at $11.99/month or $107.88/year.
Does Consensus cover all scientific fields?
Consensus covers all major domains—from astronomy to biochemistry to sociology. It indexes papers from most major academic journals and includes all of PubMed. Coverage is updated weekly, though very niche subdisciplines may have gaps.
How accurate is Consensus?
Consensus outputs are grounded in peer-reviewed literature, so accuracy depends on source quality. The platform includes quality indicators (methodology, journal prestige, citations) to identify high-caliber research. However, users should verify claims by reading original papers, especially for critical decisions.
Is my research data secure and private?
Yes. Consensus states it does not train AI models on user data, does not share data with third parties, and anonymizes search data. The platform complies with standard data privacy practices.
Can I integrate Consensus with my research tools?
Consensus integrates with Zotero, Mendeley, EndNote, and RefWorks for citation management. It's also available as a custom GPT within ChatGPT. An API is available by application for enterprise integration at $0.10+ per search call.
