What is Consensus?
AI-powered search engine for scientific research.Consensus is an AI-powered academic search engine that helps users find and understand scientific research papers using natural language questions instead of keyword searches. The platform searches across a database of over 200 million peer-reviewed scientific papers, using AI to read, analyze, and synthesize findings from relevant studies into clear, accessible summaries. When you ask a question like "Does intermittent fasting help with weight loss?", Consensus searches the scientific literature, identifies the most relevant studies, and provides a synthesized answer based on the collective findings — complete with a "Consensus Meter" showing what percentage of studies support or oppose the claim. Each result links directly to the original paper, enabling users to verify claims and dive deeper into the methodology. The Copilot feature uses GPT-4 to generate comprehensive summaries that synthesize evidence across multiple papers, essentially performing a mini literature review on demand.
