About Consensus

Consensus is an AI search engine that answers questions using peer-reviewed research instead of the open web: ask a yes/no question and its Consensus Meter shows how published studies split, with every claim linked to real papers. The free plan has unlimited searches plus 10 Pro Analyses and Study Snapshots a month; Premium is $8.99/month billed annually ($11.99 monthly), with a 40% student discount. Built for researchers, clinicians, students, and anyone who wants evidence, not vibes.

Pros

Answers grounded exclusively in peer-reviewed literature — citations are real, not hallucinated
Free tier includes unlimited searches, not a trial
Consensus Meter gives a fast read on scientific agreement no chatbot offers
Students get 40% off Premium (about $5.39/month annually)

Cons

Coverage limited to its index — paywalled full texts are often out of reach
Pro Analyses and Study Snapshots capped at 10/month on the free plan
Search-first design; no systematic-review data extraction tables like Elicit
Web only — no mobile or desktop apps

Our verdict

Best for: Researchers, clinicians, and students who need a fast, citation-backed read on what the science actually says.

Skip if: You're running systematic reviews with structured data extraction across hundreds of papers — Elicit is built for that workflow.

Our review

Consensus attacks the single worst failure mode of AI research help — confident answers with fake citations — by refusing to answer from anything but indexed, peer-reviewed literature. The Consensus Meter is the killer feature: ask 'does creatine improve cognition?' and instead of one blended paragraph you see how many studies say yes, no, or possibly, each one clickable. For clinicians, students, and anyone who argues with citations, that's a fundamentally more honest interface than ChatGPT or Perplexity.

The limits are structural. It can only read what's in its index, so paywalled full texts and very recent work create blind spots, and the free tier's 10-per-month caps on Pro Analyses and Snapshots push serious users to Premium quickly. It's also deliberately shallow compared with Elicit: there are no extraction tables, no screening workflows, no PRISMA-shaped pipelines. And with no meaningful G2 or Capterra footprint, third-party review signal is thin — one Trustpilot account of quotas shrinking mid-contract is worth noting even if isolated.

Verdict: the best first stop for 'what does the science say?' — cheap, honest about disagreement, and safe to cite from. Pair it with Elicit for formal reviews, and keep Perplexity for questions the literature doesn't cover.

What reviewers elsewhere say

82% positive — Researchers and students praise the citation-grounded answers and Consensus Meter; complaints center on index gaps, free-tier caps, and at least one report of quota terms changing mid-subscription.

Frequently asked questions

What is Consensus?

Consensus is an AI-powered academic search engine that answers questions using findings from 200M+ peer-reviewed papers. Its signature Consensus Meter shows how studies split on yes/no questions, and every answer links to the underlying research.

How much does Consensus cost?

The free plan offers unlimited searches with 10 Pro Analyses and 10 Study Snapshots per month. Premium is $8.99/month billed annually or $11.99 month-to-month; Teams runs $9.99/seat/month annually. Students get 40% off Premium.

Is Consensus reliable?

Its answers cite real, verifiable papers, which eliminates the fabricated-reference problem of general chatbots. Reliability still depends on what's in its index and how you filter — it summarizes the literature; it doesn't referee study quality for you.

Does Consensus have an API?

No public self-serve API is offered today; access is through the web app, with institutional licensing for universities and organizations.

Consensus vs Elicit — which should I choose?

Consensus is faster for evidence questions: ask, see the Meter, read the citations. Elicit is the stronger systematic-review tool, extracting structured data across many papers into tables. Casual and clinical evidence checks favor Consensus; formal reviews favor Elicit.
