About

Consensus is an AI search engine scoped to peer-reviewed literature (200M+ papers, provider-claimed). Ask a research question and it synthesizes cited answers; for yes/no questions the Consensus Meter visualizes what share of analyzed studies say yes, no, or possibly. It draws on OpenAlex/Semantic Scholar plus full-text publisher partnerships.

Pricing: free tier (limited Pro messages, Deep Reviews, Study Snapshots); Pro $20/mo ($144/yr); Deep $65/mo ($540/yr). Student/faculty discounts available. The company raised $30M in May 2026 (provider-claimed via press). Scope is papers-only — not a general web research tool.

What it can do

  • Hybrid semantic + keyword search over 200M+ papers
  • Consensus Meter: yes/no/possibly agreement visualization
  • Study Snapshots and Deep Reviews
  • Chat with full text; Zotero/EndNote export
  • Citation graph and personal library

Setup

  1. Sign up at consensus.app (free tier, no card).
  2. Ask a research question in natural language.
  3. Read the cited synthesis; check the Consensus Meter for yes/no questions.
  4. Open the underlying papers before writing — the meter summarizes, it does not appraise quality.

Prerequisites

A web browser; Consensus account (free tier available).

Trust score — 7/10

/10 trustMetrics-checked

Scored 7/10 (metrics tier). Well-reviewed with a genuinely novel feature (Consensus Meter) and generous free tier, but closed SaaS and key scale claims (10M+ users, $30M raise) are provider-claimed. Papers-only scope is a real limitation for general research. Strong metrics-tier entry.

  • · no release date — neutral maintenance score
  • · manual review: Consensus Meter verified across reviews; $30M raise May 2026 provider-claimed; scope is papers-only, not general web; license: closed SaaS
