You drag a PDF into the page, wait a few seconds for parsing, and receive a summary of the key points. From there you can ask follow-up questions the way you would with a colleague who has read every page. What distinguishes it is citation-first answering: responses reference the specific page they came from, so you can always cross-check the machine's claim against the original text. This matters most for research papers, contracts, and textbooks where accuracy is not optional. The service also suggests starter questions to help you explore a document. The free preview is limited to 2 documents, 10 questions, 200 pages, and 32 MB per file, which is enough to run one document end to end. Paid plans are month-to-month and cancellable in one click. On privacy, the company states documents are never used to train models and can be deleted at any time, removing the file and its data. **Pricing & Plans:** Freemium.

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) ## Frequently Asked Questions ### How do ChatPDFGPT and Consensus compare in monthly traffic?
