Explainpaper

Overview

Explainpaper is a purpose-built research paper reader designed to significantly reduce the time required to understand dense academic texts. By integrating Large Language Models (LLMs) into the reading workflow, the platform enables users to highlight confusing sentences or passages and immediately receive simplified, in-context explanations. The tool removes the friction of decoding jargon, allowing researchers to focus on ideas rather than terminology. It supports over 50 languages and offers adjustable complexity levels, from beginner to expert, ensuring that explanations align with the user's background and needs.

Beyond basic highlighting, Explainpaper introduces a conversational layer for each document. The “Chat with Your Paper” functionality lets users ask questions and obtain precise answers grounded in the actual paper content, not generic knowledge. Responses include citations to specific sections, making it easy to jump directly to the relevant part. Users can pose follow-up questions for deeper exploration and request summaries of key results, effectively turning a static PDF into an interactive, interrogable knowledge source.

The platform also generates auto-driven insights that reveal a paper's structure, principal findings, and core arguments without requiring a full read. Smart outlines support navigation through long documents, key-point extraction surfaces the most important information, and concept relationship mapping clarifies how ideas interconnect. These capabilities accelerate literature review, enhance comprehension, and support rigorous analysis of scientific publications.

With over 400,000 researchers already using the tool, Explainpaper offers a freemium pricing model: a free tier provides unlimited highlight explanations and basic AI interactions, while a 7-day Pro trial unlocks advanced AI models, full-paper summaries, saved highlights, and the full question-answering experience. The service is ready to use in under a minute, requiring no credit card to start.
