Yes. The free tier includes unlimited Papers searches, 10 Pro messages, 3 Deep reviews and 10 Study Snapshots per month. Paid plans mainly buy unlimited Pro messages and much larger Deep Review allowances.

What is the Consensus Meter?

For questions that studies answer yes or no, the Meter shows the share of relevant papers concluding yes, possibly or no, based on their abstracts and results. It is a quick read on how settled a question is, not a verdict on any single study.

How is a Deep Review different from a normal search?

A normal search returns and summarizes individual papers, while a Deep Review reads across many papers and writes a structured synthesis of what they collectively find. Because it is compute-heavy, Deep Reviews are capped monthly on every plan — 3 on Free, 15 on Pro, 200 on Deep.

Does Consensus search the whole web?

No. Consensus only searches its corpus of peer-reviewed academic papers, which keeps answers grounded in published research but means it will not surface news, preprints outside the corpus or general web sources.

Consensus 是什么？

Consensus is a search engine that answers research questions from peer-reviewed literature instead of the open web. Built by Consensus NLP, founded in 2021 by Eric Olson and Christian Salem, it searches more than 200 million academic papers and uses AI to synthesize what the studies collectively say, with claims linked back to the papers they came from. For yes-or-no questions, its Consensus Meter shows how the body of studies splits between yes, possibly and no.

Three depths of answer cover different jobs: ordinary Papers search, Pro Analysis for synthesized answers, and Deep Review, which reads across many papers to produce a structured literature summary. Study Snapshots pull one paper's population, methods and outcomes into a card, and filters narrow results by study type, sample size and journal quality. An API and MCP access let other AI tools query Consensus directly. It suits students, clinicians and researchers who want a fast, cited answer to what the evidence says before committing to a full review.

如何使用 Consensus

1
Ask a research question
Type a question in natural language — the more specific, the better the synthesis — and Consensus searches the paper corpus, not the web.
2
Read the synthesized answer
Check the Pro Analysis summary and the Consensus Meter, then open the linked papers behind any claim you plan to rely on.
3
Run a Deep Review for bigger topics
Spend one of your monthly Deep Reviews to get a structured summary built from many papers at once.
4
Filter and save snapshots
Narrow by study design or journal quality and open Study Snapshots to compare papers quickly.
