Consensus

General AI search will confidently answer a research question from whatever is on the open web. Consensus takes a stricter path: answer from peer-reviewed literature, and show the papers.

It is an AI academic search engine over hundreds of millions of research papers, with a Deep Search that automates literature review, a Medical mode for clinical sources, and natural-language filters, used across 170+ university libraries. It sits among research tools like Gemini Notebook and consumer search like Perplexity AI, distinguished by its peer-reviewed foundation.

This review covers how Consensus runs a literature review, who it suits, how it prices research access, and where another tool fits better.

Consensus, The Research Brief

• Consensus is an AI academic search engine: it searches and analyses hundreds of millions of peer-reviewed papers.
• Deep Search automates literature review: building a search strategy, expanding terms and exploring the citation graph.
• It is grounded in real research: drawing on peer-reviewed literature and licensed full-text content, with citations.
• It has a Medical mode: narrowing to top clinical guidelines and journals for trusted medical answers.

Consensus Research Facts

An AI Search Engine Built On Peer-Reviewed Papers

Consensus's defining choice is its corpus: instead of the open web, it searches and analyses peer-reviewed research papers, hundreds of millions of them, including licensed full-text content from leading publishers. For anyone who needs defensible answers, that foundation is the whole value.

That is the difference between a plausible answer and a cited one. Consensus is built to save research time without sacrificing academic rigour, surfacing what the literature actually says and letting you see the studies behind it.

Its adoption signals back this up: it reports partnerships with 170+ university libraries and millions of users across students, researchers and clinicians. Those are vendor-stated, but the institutional footprint is a meaningful indicator for a research tool.

The difference is between a plausible answer and a cited one. Consensus answers from peer-reviewed literature and lets you see the studies behind it.

How Does Consensus Run A Literature Review?

Two capabilities do the heavy lifting: Deep Search, and the modes and filters that keep results rigorous.

Deep Search Across Millions Of Papers

Deep Search turns days of literature review into minutes: it builds a comprehensive search strategy, expands key terms, identifies conflicting arguments and explores the citation graph, then synthesises what the research agrees and disagrees on, with sources.

That automated-review depth is where it goes beyond a search box. A source-grounded tool like Gemini Notebook works from documents you supply; Consensus brings the whole peer-reviewed corpus and the review strategy to the question.

Medical Mode And Natural-Language Filters

A Medical mode narrows to high-quality clinical sources, clinical guidelines and top medical journals, for trusted clinical answers, and natural-language filters let you specify timeframe, population, study design and more directly in the prompt, which Consensus applies automatically.

Those controls are what make it rigorous rather than merely fast. A consumer AI search like Perplexity AI answers general questions from the web; Consensus is purpose-built for evidence from the literature, which is a different and narrower job.

Who Consensus Suits Among Researchers

Consensus suits researchers, graduate students, academics and clinicians who need evidence-based answers grounded in peer-reviewed literature, and who do real literature reviews where speed without rigour is no help.

It especially suits anyone doing systematic or semi-systematic reviews, where Deep Search's strategy-building and citation-graph exploration save substantial time, and clinicians who want answers from trusted medical sources via Medical mode. The institutional library access makes it practical at universities. For discovery through an indexed citation database rather than an AI synthesis, a tool like Web of Science Research Assistant approaches the same literature from a different angle.

It suits less well someone wanting quick general-knowledge answers, where a consumer AI search is faster and broader, and anyone outside research who does not need peer-reviewed grounding. And, as always with AI, you should still read the cited papers rather than trusting a synthesis blindly.

How Consensus Prices Research Access

Consensus is freemium: a free tier to search, paid plans for more (including Deep Search and advanced use), plus institutional access through university libraries and organisation plans. We do not publish prices, which change; check the site.

For an individual researcher, the value question is whether it meaningfully speeds literature review and surfaces evidence you would otherwise miss, which for anyone doing real reviews it usually does.

Many users get it through a university library, so check whether your institution already provides access before paying individually, and use the free tier to judge the quality of its answers on your own topics.

A Neat Way To Try Consensus

Because the point is rigorous, cited answers, test Consensus on a real research question you know well.

1. Ask a research question in your own field and check whether the cited papers are relevant and real.
2. Run a Deep Search on a topic you have reviewed before and compare its synthesis to what you know.
3. Use natural-language filters (timeframe, population, design) and confirm it applies them correctly.
4. If clinical, try Medical mode and judge the quality of the sources it narrows to.
5. Check whether your university library already provides access before paying.
6. Pass/fail: Consensus is worth it if it speeds real literature review and surfaces evidence you trust.
7. Always read the cited papers; do not treat the synthesis as a substitute for the sources.

Consensus Research Terms

Peer-reviewed

Research that has been evaluated by other experts before publication; the standard for credible academic evidence.

Literature review

A structured survey of existing research on a topic; Deep Search automates much of the search and synthesis.

Citation graph

The network of which papers cite which; exploring it helps find key and related work.

Systematic review

A rigorous, method-driven review of all relevant studies on a question; the kind of work Deep Search can accelerate.
