Explainpaper
FreeResearchAcademicNEWAI tool that explains confusing sections of academic papers in simple, easy-to-understand language.
Overview
Explainpaper is a simple, focused AI tool that helps readers understand difficult sections of academic papers. Users upload a paper, highlight any confusing passage, and the AI provides a clear, plain-language explanation of what it means. This targeted approach is different from tools that summarize entire papers - Explainpaper is designed for the moments when you understand most of a paper but get stuck on specific paragraphs, equations, or technical jargon.
The tool uses large language models to parse complex academic language and restate it in accessible terms, making it particularly valuable for students reading papers outside their specialty, researchers engaging with interdisciplinary literature, and anyone encountering dense technical writing. Explanations can be iteratively refined by asking follow-up questions about the highlighted section.
Explainpaper is free to use and requires no account for basic functionality, reflecting a commitment to making academic knowledge more accessible. Its simplicity is its strength - there is no complex interface to learn, just upload, highlight, and understand.
