  • Content creators who need credible sources

Pros

  • Answers built from academic papers, not random websites
  • Shows how many studies support or contradict a claim
  • Filters for study type, sample size and publication year
  • Saves time finding relevant papers

Cons

  • Limited to topics covered by academic research
  • Summaries can oversimplify study limitations
  • Some advanced features are limited on the free plan

What is Consensus?

Consensus is an AI-powered academic search engine. Ask a question in normal language, like “Does intermittent fasting improve blood pressure?”, and Consensus finds relevant peer-reviewed studies, pulls out their key findings and summarises what the research as a whole suggests. Every point links to a real paper, which makes it far more reliable for evidence-based questions than a general chatbot answering from memory.

Key features

  • Question-based search. Type full questions instead of keywords.
  • Summaries of findings. Get a short synthesis of what the top studies found.
  • Consensus Meter. For yes/no questions, see how studies are distributed across yes, possibly and no.
  • Study details. Quickly see study type, population and whether a paper is highly cited.
  • Filters. Narrow results by year, study design (for example randomised controlled trials), field or journal quality.
  • Deeper analysis. Ask follow-up questions and generate longer research overviews.

How to get started

  1. Go to consensus.app and search a question you care about.
  2. Read the synthesis at the top, then open the individual studies.
  3. Apply filters, such as recent years or randomised controlled trials, for stronger evidence.
  4. Save useful papers and export citations for your work.
  5. Sign up to unlock AI summaries and saved searches.

Who Consensus is for

Students and academics starting a literature review, journalists and bloggers who want to back claims with research, health and fitness professionals, product teams checking the science behind a feature, and curious people tired of contradictory advice online.

Tips for better results

  • Ask neutral questions. “Does X affect Y?” gives more balanced results than “Why is X good?”
  • Check study quality. Prefer meta-analyses and large trials over small single studies.
  • Look at dates. Science moves; recent reviews may overturn older findings.
  • Write it up clearly. When turning research into an article, check the length and reading time with the free word counter and avoid overusing technical terms with the keyword density checker.

Consensus vs alternatives

Elicit goes deeper into structured literature reviews and data extraction from papers. Perplexity searches the whole web, including news and blogs, and can focus on academic sources too. NotebookLM is ideal once you have your papers and want to study them in depth. General assistants like ChatGPT are better at explaining concepts than at finding specific studies.

Is Consensus worth it?

If you ever need to know what the evidence says rather than what someone claims, Consensus is one of the fastest ways to get there, and the free plan covers occasional questions well. Students and researchers who search daily will likely want a paid plan for unlimited analysis. Always remember it’s a starting point: read the key papers before drawing strong conclusions.

Consensus: common questions

Is Consensus free?

Yes. You can search Consensus for free and use its AI summaries with a monthly limit. Paid plans unlock unlimited advanced features for heavy research use.

Where does Consensus get its papers?

Consensus searches a large database of academic papers across science, medicine, social sciences and other fields, and links each result to the original publication.

What is the Consensus Meter?

For yes-or-no questions, such as whether a supplement improves sleep, Consensus shows how the relevant studies lean, giving a quick visual sense of the evidence.

Can I cite Consensus in an essay?

Cite the original papers, not Consensus. Use it to find and understand studies, then read and reference the papers themselves.

Is Consensus good for medical advice?

It helps you understand what research says, but it is not a doctor. Discuss health decisions with a qualified professional.
