How it works
The tool is made for evidence-based work: students writing papers, researchers doing literature reviews, clinicians checking what the evidence says, and policy makers who need trustworthy sources. Every claim in an answer links back to a paper, so you can verify it yourself instead of trusting a chatbot's word.
The free plan includes unlimited paper searches, 10 Pro messages a month, and 3 Deep reviews a month — enough to test it properly. Pro is $12 per month on annual billing ($144 a year) or $20 month to month, with unlimited Pro messages and 15 Deep reviews a month. Deep is $45 per month on annual billing for heavy researchers. Students get a 40% discount with a verified student email.
