Overview
Explainpaper is an AI reading assistant designed to make dense academic papers accessible to readers who aren't experts in the specific field. Founded in 2022, it lets users upload any academic PDF and then highlight confusing text to get an instant, plain-language explanation — powered by large language models that understand scientific context.
The tool solves a specific, painful problem: academic papers are written for specialists, making them nearly impenetrable for students, researchers entering adjacent fields, or practitioners trying to apply scientific findings. Explainpaper acts as a knowledgeable colleague who can explain any section of a paper in plain language at the reader's chosen level of expertise.
In 2026, Explainpaper has expanded from individual paper explanation to features supporting systematic reading — summarizing full papers, generating key takeaways, and comparing multiple papers on the same topic. It has become a popular tool for graduate students, practitioners reading outside their specialty, and science communicators.
Key Features
Highlight & Explain
Upload any PDF and highlight confusing passages for instant AI explanation. The AI provides context-appropriate explanations based on the surrounding paper content.
Full Paper Summary
One-click AI summary of the entire paper: research question, methodology, key findings, and implications. Understand a paper's value before deep reading.
Jargon Simplifier
Automatically identifies and explains technical jargon throughout a paper. Toggle between technical and simplified language.
Q&A with Papers
Ask questions about the paper in natural language. "What evidence supports the main claim?" "What are the main limitations?" The AI answers from the paper.
Key Takeaways
AI-generated bullet points of the most important conclusions and contributions. Quick triage for whether a paper deserves deep reading.
Multi-Paper Comparison
Compare findings across multiple papers on the same topic. Understand where papers agree, disagree, and complement each other.

How It Compares
Explainpaper vs SciSpace (Typeset)
SciSpace offers similar AI paper explanation with additional literature search features. Explainpaper's highlight-and-explain interaction is more intuitive for paper reading. Both serve overlapping use cases.
Explainpaper vs ChatGPT for papers
ChatGPT can explain concepts but lacks paper-specific context and may hallucinate. Explainpaper grounds explanations in the actual uploaded paper content, making it more accurate for specific paper questions.
Final Verdict
Our Recommendation
Explainpaper does one thing — make academic papers readable — and it does it very well. The highlight-and-explain interaction model is immediately intuitive and genuinely useful for anyone who has ever struggled with dense academic jargon. For graduate students working across disciplines, practitioners trying to apply research findings, or anyone who wants to understand the science behind news claims, Explainpaper provides an accessible, reliable reading assistant. It democratizes access to scientific knowledge in a meaningful way.
