Explainpaper helps you read academic papers. You upload a PDF, highlight a sentence or paragraph you do not understand, and it explains it in simpler words. You can then ask follow-up questions.
Students use it while reading for assignments and theses, and it can import papers from a Zotero library. The Pro plan can also explain graphs, figures and equations, build outlines with page references and save your explanations.
The free plan includes unlimited highlight explanations and follow-up questions using basic AI models. Pro costs $16 a month (yearly billing saves 25%) with a 7-day free trial. Team pricing is on request, and payments go through Stripe.
It works in the browser. Always check explanations against the paper itself, especially for technical details.
