Consensus

Consensus searches over 200 million peer-reviewed research papers and synthesizes findings using AI. Instead of returning a list of papers, it extracts conclusions — showing you whether studies agree, disagree, or have mixed findings on a question. The free tier gives limited searches per month. The Premium plan ($9.99/month or $89/year) adds unlimited searches, GPT-4 synthesis, and the Study Snapshot feature.

For anyone doing literature reviews, health research, or evidence-based decision making, this is the tool Google Scholar should have been. The Consensus Meter shows what percentage of papers agree with a claim, which is genuinely useful for understanding scientific consensus.

Where it falls short: only covers peer-reviewed academic literature, so it misses business research and industry reports. The free tier is too restricted for daily academic use. Not a replacement for actually reading papers, but extraordinary for quickly orientating yourself in an unfamiliar research area.
