Consensus review

Consensus answers questions from the research literature instead of the open web. It searches 400M+ peer-reviewed papers and scholarly works, and its agents read the papers, pull the data and cite each claim. The free plan keeps basic paper search and includes 10 Pro messages and up to 3 deep reviews a month, which is enough to test it on a real assignment. Pro, at $12 a month billed as $144 a year, removes the cap on Pro messages, raises deep reviews to 15 a month and opens every research tool, including the citation graph, plus five times the API and MCP usage. Deep is aimed at researchers and clinicians who run frequent literature reviews, with 200 deep reviews a month. Students, faculty with a school email and US clinicians with an NPI number can get up to 40% off. The caveats are that it only searches scholarly literature, and the deep review allowance decides which plan you need, with Deep at $45 a month billed annually.
