What is Explainpaper?
AI That Explains Academic Papers in Plain Language
Explainpaper is an AI tool designed specifically for reading and understanding academic research papers. Users upload a paper, highlight any confusing passage, and the AI provides a clear, plain-language explanation of that specific text — making dense academic writing accessible to students, professionals, and curious readers who encounter papers outside their area of expertise.
Highlight, Ask, Understand
The interaction model is elegant: rather than asking broad questions about a document, users highlight the exact sentence or paragraph they find confusing, and the AI explains precisely that text. This targeted approach means explanations are contextually specific and immediately relevant to what the reader is trying to understand. Explainpaper supports a wide range of academic fields from computer science to biology and economics.
