Explainpaper is a web app for reading research papers. The homepage says you can highlight confusing text and get instant, simple explanations. The pricing page lists a free plan with unlimited highlight explanations, follow-up questions, and Zotero library import, powered by basic AI models. The Pro plan costs $16 per month and adds math and figure explanations, advanced AI models, full-paper summaries, and saved highlights. Teams can contact the company for team management, priority support, and volume discounts. All plans are billed through Stripe. The homepage shows testimonials from researchers, but these are user quotes, not independent test results. The site does not state whether an API or open-source license is available, so those facts are unknown. A sign-in link appears on the homepage, but the page does not clearly say an account is required to use the tool.
