Consensus

Consensus solves a specific problem better than any general-purpose AI: it answers questions using only peer-reviewed scientific research. Ask "does creatine improve cognitive function?" and instead of a ChatGPT-style synthesis that might include blog posts and Reddit threads, Consensus searches 220 million scientific papers and returns a summary backed exclusively by published research — complete with a Consensus Meter showing how much the scientific literature agrees or disagrees.

This matters because the biggest problem with using ChatGPT or Claude for research is hallucinated citations — they'll confidently cite papers that don't exist. Consensus can't hallucinate sources because it only surfaces real, indexed papers. Every claim links back to an actual publication you can verify. For students, healthcare professionals, and anyone who needs evidence-based answers, this reliability is worth more than any general AI's broader capability.

The free tier is limited to 20 searches per month — enough to get a feel for the tool but not enough for serious research. Pro at $10/mo unlocks unlimited searches with GPT-4-powered summaries, and the 40% student discount brings it to $6/mo, making it very accessible for academics. The Deep tier at $45/mo adds comprehensive literature review capabilities for professional researchers. Consensus won't help you write code or generate images, but for its specific domain — finding what science actually says about a question — it's the best tool available.
