Consensus is an AI-powered academic search engine founded in 2021 by Eric Olson (CEO) and Christian Salem. Headquartered in the US, the company has built a corpus of 220M+ peer-reviewed papers drawn from OpenAlex and Semantic Scholar, supplemented by exclusive full-text partnerships with Taylor & Francis, Sage, and the American Chemical Society. As of 2026, Consensus has relationships with 170+ university libraries.
The product's core premise is answering research questions with citations rather than hallucinations. Users type a natural-language question and receive ranked paper results, per-paper Study Snapshots, and a Consensus Meter that aggregates findings across top-cited studies into a yes/no/possibly verdict. In late 2025, Consensus launched Scholar Agent — a multi-agent system built on GPT-5 and the OpenAI Responses API — enabling fully automated literature review workflows that previously took days. A concurrent Medical Mode filtered the corpus specifically for clinical guidelines and high-impact medical journals, strengthening the tool's appeal for evidence-based medicine.
A September 2025 head-to-head evaluation against Google Scholar across 500 queries gave Consensus 4.6% higher average precision. Coverage is strongest in life sciences, medicine, and physical sciences; humanities and qualitative social science research are noticeably thinner.
Key Benefits
- Evidence-grounded answers: Every claim links directly to peer-reviewed sources; the Consensus Meter shows whether the literature broadly agrees or is split.
- GPT-5 Scholar Agent: Automates multi-step literature reviews end-to-end, compressing days of reading into minutes with structured, cited outputs.
- Affordable academic pricing: At $10/month annually (or $6/month with a student discount), it undercuts direct competitors like Scite (~$20/month) and Elicit Pro (~$50/month).
- Medical Mode: Clinicians get a purpose-filtered corpus of clinical guidelines and top-journal articles, useful for rapid evidence checks at the point of care.
Use Cases
- Graduate thesis research — Run a Deep Search on a complex research question and receive a structured literature overview with methodology breakdowns and citation maps.
- Clinical evidence checks — Use Medical Mode to quickly surface guideline-level evidence on a treatment question without manually searching PubMed.
- Science journalism and policy writing — Verify factual claims against the academic record and surface the Consensus Meter verdict on contested scientific questions.
- Corporate R&D scoping — Assess prior art and published findings in a technical domain before investing in a research direction.
