Explainpaper is an AI-powered research reading tool trusted by over 400,000 researchers, students, and academics worldwide. Designed to remove the barrier of dense academic jargon, it allows users to upload any research paper and interact with it in an entirely new way. Simply highlight any confusing sentence or passage and receive a clear, context-aware explanation generated by a large language model—no more getting stuck on unfamiliar terminology. Beyond highlight explanations, Explainpaper offers a chat interface that lets users ask targeted questions about the paper's content, dive deeper into specific topics with follow-up questions, and jump directly to the cited sections. The tool also auto-generates structured outlines, key point extractions, and concept relationship maps so users can grasp a paper's core arguments without reading every line. Explanations can be tuned from beginner to expert level and are available in 50+ languages, making the tool accessible globally. The free tier offers unlimited highlight explanations and basic AI-powered Q&A, while the Pro plan ($16/month) unlocks advanced AI models, full-paper summarization, and the ability to save highlights and explanations for later reference. Whether you're a grad student digesting ML papers, a professional researcher reviewing literature, or a curious learner exploring new fields, Explainpaper dramatically accelerates comprehension and confidence.
