How to Use Explainpaper in 2026: Step-by-Step Guide
Explainpaper lets you highlight any confusing section of an academic paper and get a plain-language explanation instantly. Upload any PDF, click on the dense terminology, jargon, or math that's blocking your understanding, and the AI explains it at the level of detail you need — bridging the gap between academic writing and actual comprehension.
Explainpaper (explainpaper.com) is an AI tool built for a universal frustration: trying to read a technical academic paper and hitting a paragraph so dense with jargon, acronyms, or mathematical notation that you have to stop and look up a dozen things before you can continue. Explainpaper turns that friction into a one-click interaction.
How it works
Users upload a PDF paper (or paste a link to arXiv). The paper is displayed in a split-screen view — paper on one side, AI explanation panel on the other. Highlight any text in the paper and the AI immediately generates an explanation tailored to the surrounding context. It knows what field the paper is in, what the surrounding sections are about, and explains the highlighted passage in relation to the whole.
For mathematical notation, the AI translates equations into plain language. For technical terminology, it defines the term and explains why it matters for the paper's argument. For dense methodology sections, it unpacks what the authors actually did in accessible terms.
AI chat
Beyond the highlight-and-explain feature, Explainpaper includes an AI chat interface where users can ask questions about the paper in free-form natural language: 'What is the main finding?', 'What are the limitations of this study?', 'How does this compare to the 2021 transformer paper?' The AI generates answers grounded in the paper content.
Who uses it
Explainpaper is used by undergraduate and graduate students reading outside their specialty, researchers encountering adjacent-field papers, and practitioners reading technical AI, medical, or scientific papers. It's particularly popular among AI/ML practitioners trying to understand recent papers.
Frequently Asked Questions
Is Explainpaper free? There's a free tier that allows a limited number of explanations per day. The Plus plan ($12/month) removes limits and adds priority AI access. Can it handle math? Yes — mathematical notation is one of Explainpaper's strongest use cases. The AI explains the intuition behind equations rather than just restating the notation. Does it work for all paper types? It works best for papers in English from established academic fields. Coverage is strongest for CS, biology, medicine, and economics.

Natural Language Chat
Type your question or task in natural language. Explainpaper excels at understanding context and providing helpful, detailed responses.
Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show Explainpaper what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
