Instead of returning a flat list of PDFs, you ask a natural-language research question and Consensus extracts claims from relevant papers, then shows you what the studies actually find. A Consensus Meter summarizes the weight of evidence for yes/no questions, so you can see at a glance whether scientists largely agree, disagree, or remain divided. The platform indexes hundreds of millions of peer-reviewed papers spanning medicine, biology, psychology, economics and more. Answers link straight back to the source studies, and you can filter by study design, journal quality, sample size and publication year to separate stronger evidence from weaker signals. Features like Deep Search, Topic Synthesis and Skills let researchers build a working knowledge base over time rather than starting from scratch on every query. Consensus is designed for researchers, clinicians, students and analysts who need trustworthy signals from the scientific record without drowning in irrelevant results. A free tier gives limited AI-powered searches each month, while paid plans unlock unlimited use, advanced filters and deeper synthesis. **Pricing & Plans:** Freemium. A free tier offers a limited number of AI-powered searches per month; paid individual plans unlock unlimited searches and advanced research features, with discounted student pricing and team/enterprise options. - **Evidence-grounded answers:** Ask a research question in plain language and get answers synthesized from peer-reviewed studies, with each claim linked to its source paper. - **Consensus Meter:** A visual summary shows how the scientific literature leans on a yes/no question, indicating agreement, disagreement or mixed evidence. - **Powerful filters:** Narrow results by study design, sample size, journal quality, publication year and more to prioritize high-quality evidence. - **Topic synthesis and Deep Search:** Aggregate findings across many studies into structured summaries that map what is known and where the gaps are. - **Research workspace:** Save papers, organize sources and build a persistent knowledge base for literature reviews and ongoing projects. **Strengths:** Answers cite real peer-reviewed papers, so claims are verifiable; Consensus Meter makes it easy to gauge scientific agreement at a glance; Rich filters help separate high-quality evidence from weaker studies; Fast, clean interface designed around research workflows **Limitations:** Free tier caps the number of AI-assisted searches per month; Coverage is strongest for STEM and health fields, lighter for some humanities topics; It guides you toward sources but is not a substitute for reading full papers [Profile (Markdown)](https://openaitools.app/tool/consensus.md) ## PDF Talk PDF Talk is an AI-powered assistant built specifically for interacting with PDF documents. Instead of reading a long report page by page, you upload the file and have a conversation with it: ask what a section says, request a summary, or query a specific figure. The assistant answers using the document's own content, which turns dense PDFs into something you can question directly. The core value is speed. Students reviewing papers, analysts scanning reports and professionals working through contracts often only need a handful of answers from a hundred-page file. PDF Talk is designed to surface those answers through natural-language questions and dynamic responses, rather than making you hunt for them. It also generates summaries so you can grasp the key points first and drill in only where it matters. The product is classified here as a paid, AI-native PDF chat tool.
