What it is
Explainpaper is a web-based AI reader for research papers. Readers highlight confusing passages and receive explanations with adjustable complexity, support for more than 50 languages, and context from the full paper. Paper chat answers questions from a paper, supports follow-up questions, and can summarize findings; answers may cite sections so readers can locate the relevant material. The product also creates outlines, extracts key points, and shows relationships between concepts. The Free plan is available indefinitely and includes unlimited highlight explanations, follow-up questions, Zotero library import, and basic AI models. Pro costs $16 a month and adds Math Explain for formulas and figures, advanced AI models, whole-paper summaries, saved highlights and explanations, and paper questions. Pro includes a 7-day free trial, with a card required to start it. Teams adds team management, priority support, and volume discounts, with pricing not listed. Subscriptions are billed monthly or annually according to the selected plan through Stripe. Explainpaper describes use by more than 400,000 researchers.
