Instead of parsing equations, acronyms, and field-specific jargon alone, you upload a PDF and highlight whatever you don't understand. The tool returns a short, contextual explanation of that passage, and you can dial the complexity up or down to match whether you're a newcomer to the field or an expert skimming for detail. The explanations are context-aware: the model reads the surrounding paper so a highlighted term is explained in the sense the authors actually meant, not in a generic dictionary sense. You can request answers in more than 50 languages, which makes English-language research accessible to readers worldwide. Beyond highlights, a chat mode lets you ask follow-up questions about the paper and get answers drawn from the document itself, with pointers back to the relevant sections. ExplainPaper also extracts structure for you. It can produce a smart outline, pull out the key findings and main arguments, and show how concepts in the paper connect. The service is used by a large community of researchers and is offered free with usage limits, with a paid Pro tier that unlocks stronger models, whole-paper summaries, and saved highlights. **Pricing & Plans:** Freemium. The free tier costs $0 and includes unlimited highlight explanations, follow-up questions, and access to basic AI models. Pro is listed at $16/month and adds explanations powered by a more advanced model, whole-paper summaries, saved highlights and explanations, and paper Q&A, after a 7-day Pro trial that requires a card on file.
