In short

Explainpaper wraps an LLM around PDF reading to explain dense academic papers. It is best for researchers who want inline explanations and chat without leaving the document.

Best for

Pick Explainpaper if you read a lot of dense academic papers and want an inline highlight-to-explain workflow rather than juggling chatbot tabs.

Skip if

Skip it if you need an API, on-prem deployment, or a general document-Q&A tool that handles contracts, reports, and code as well as papers.

Explainpaper is a research paper reader that wraps an LLM around the PDF reading experience. Upload an academic paper, highlight any confusing passage, and the tool returns a plain-language explanation tuned to a complexity level you choose (beginner through expert). You can also chat with the full paper, ask follow-up questions in context, and pull auto-generated outlines and key points instead of grinding through the abstract and methods sections cold.

It is aimed squarely at grad students, researchers crossing into adjacent fields, and curious non-specialists trying to keep up with arXiv. The free tier covers unlimited highlight explanations and follow-ups, while the $16/month Pro plan unlocks advanced models, full-paper summaries, saved highlights, and translations across 50+ languages. There's a 7-day Pro trial that doesn't ask for a card up front.

It is a closed, hosted SaaS with no public API or self-hosting story, and the site is coy about which underlying models power the free vs. Pro tiers. If you already live in a more general AI workspace (NotebookLM, ChatGPT with PDFs, Claude Projects), Explainpaper's edge is the inline highlight-to-explain UX rather than raw model quality.

Editor's take

Explainpaper nails one job: making arXiv-grade prose readable without leaving the PDF. It's a nice-to-have rather than a must-have now that Claude Projects and NotebookLM can do similar work on any document, but the highlight-first UX is still the most natural way to read a hard paper.
