Explainpaper Review
Research & EducationFreemiumAI tool that explains complex research papers in plain language — highlight any passage and get an instant, simple explanation.
What Is Explainpaper and How Does It Work?
Explainpaper is an AI-powered reading tool that turns unreadable research papers into understandable text. After you upload a paper, it renders the document in a clean reader view. When you highlight any sentence or paragraph, Explainpaper explains that exact passage in simple language — and you can keep drilling into follow-up questions about the same section.
It works by pairing your highlighted text with the paper's context and sending it to a large language model, so explanations stay grounded in the actual document rather than being generic.
Explainpaper Features: Highlight-to-Explain, Definitions & More
The core workflow is deceptively simple.

Explainpaper vs Consensus vs Elicit
The three tools solve different parts of the research pipeline. Elicit finds and screens papers, Consensus answers your question by synthesizing the evidence across many studies, and Explainpaper helps you actually read and understand a single paper line by line.
Most serious researchers end up using all three: Elicit and Consensus to find the key studies, Explainpaper to power through them.
