Consensus vs PaperLens
Side-by-side comparison of features, pricing, ratings, and alternatives.
Consensus is an AI research tool built specifically for academic and clinical literature, searching and analyzing over 250 million research papers, including licensed full-text content from leading publishers. Its Deep Search feature automates literature reviews by building a search strategy, expanding key terms, identifying conflicting arguments, and exploring the citation graph, turning what the company describes as days of manual review into minutes. A Medical mode narrows results to roughly 50,000 clinical guidelines and 8 million articles from top medical journals for faster clinical answers, while the Consensus Meter gives a visual read on how much existing evidence agrees or disagrees on a yes/no research question. Over 170 university libraries partner with Consensus, and the company says more than 10 million researchers, students, and clinicians use it; pricing runs free up to a $45/month Deep plan for frequent literature reviews.
PaperLens is an AI-powered research assistant that provides evidence-backed answers grounded in millions of peer-reviewed papers. It helps researchers, students, and professionals quickly find, understand, and organize scientific literature.
PaperLens offers two subscription tiers: Starter at $15/month or $8/month billed annually, and Pro at $50/month or $20/month billed annually.
