Consensus

Last updated June 16, 2026 ยท Reviewed by ToolForge Editorial

The AI search engine for scientific research. Answers backed by peer-reviewed papers.

โ˜… 4.7/5 ยท 500K+ researchers ยท Since 2021 ยท 20 searches/mo free

Google Scholar, but with answers

Consensus is a search engine that only indexes peer-reviewed scientific papers. Ask 'Does creatine improve memory?' and it synthesizes an answer from 50+ studies, showing the consensus (yes, in specific populations) and citing every paper. The Pro tier adds GPT-4 synthesis, study-level detail, and the 'Consensus Meter' that visualizes the strength of scientific agreement on any claim. Used by academics, journalists, and evidence-based professionals.

Who it's for: Researchers, academics, journalists, medical professionals, and anyone who needs scientifically-backed answers. Especially valuable for health, nutrition, and psychology questions where misinformation is rampant.

Key features

๐Ÿ”ฌ Peer-Reviewed Only

Index is restricted to papers from journals with editorial review. No blog posts, no Medium articles, no SEO content farms. Just science.

๐Ÿ“Š Consensus Meter

Visual representation of how strongly the literature agrees. 'Strong consensus for,' 'mixed evidence,' 'no consensus.' Instant at-a-glance credibility check.

๐Ÿง  GPT-4 Synthesis (Pro)

Pro tier synthesizes findings across studies into readable answers with citations. The 'TLDR for 50 papers' feature.

๐Ÿ“ˆ Study Quality Filters

Filter by sample size, study type (RCT, meta-analysis, observational), and population. Critical for evaluating evidence strength.

The honest take

โœ“ What works

  • Only peer-reviewed sources โ€” no more 'wellness guru' misinformation
  • Consensus Meter is unique and immediately useful
  • Pro tier is cheap ($9/mo) for the value provided
  • Perfect for health/nutrition/psychology questions where evidence matters
  • Excellent for journalists, researchers, and skeptical professionals

โœ— What doesn't

  • Limited to science โ€” useless for general knowledge questions
  • Free tier is too restrictive (20 searches/mo) for regular use
  • Some legitimate questions have no peer-reviewed research yet
  • Studies can be contradictory; Consensus surfaces this but doesn't resolve it

Verdict

If you do any evidence-based work โ€” research, medicine, journalism, policy โ€” Consensus is essential. It's not a Perplexity replacement, it's a complement. Use Perplexity for general research, Consensus for science-grounded answers.
