Part 1. What is Explainpaper?

Explainpaper is simply an AI-powered reading and explanation tool that allows users to upload academic papers, research papers, and many other documents in PDF format.  

Explainpaper utilizes an AI chatbot with GPT-4 capabilities to provide clear explanations for complex information. The objective of this web-based tool is to help users to comprehend information easily and save time in the process.

You can start using Explainpaper for free. Nevertheless, to access all features, you need to upgrade the plan, with its pricing starting at around $12 per month.

How Does It Work?

Let us understand how Explainpaper works. You can start using the web app for free by signing up. You can start uploading documents in .pdf format or pasting the PDF link. Then, the app will take you to its reading mode.

In the reading mode, you will find three tabs on the right-hand side panel—Paper, Explain, and Chat.

Under Paper, you will find the AI automatically providing a gist of the research paper. You will need to upgrade to a paid plan to have it generate a detailed outline for your paper.

Under Explain, you can have the AI explain different terms and paragraphs for you. Simply highlight any text, sentences, paragraphs, or even mathematical equations, and ask the AI to start explaining it.

You can even ask follow-up questions and the AI chat will instantly generate more explanations for your questions.

Under Chat, you can have the AI to summarize your paper, provide a detailed assessment of the significance of the paper, and look up similar papers to what you have. However, this is only available to premium users.

Part 2. Is Explainpaper All That Worth It?

To understand if Explainpaper is fully worth using, it is best understood by going through its pros and cons.

Here are some benefits of using it and some drawbacks observed from using Explainpaper:


  • It quickly provides a clear explanation for complex terminologies and equations. Moreover, allows users to keep asking follow-up questions.
  • One can easily scroll and jump from one page to another, making it easy to read hundreds of pages.
  • It can save and store PDF files securely and retrieve them for later use.
  • Users can adjust their reading mode preview according to their comfort. For example, there is light and dark mode available.


  • Its free version has limited features. Users need to subscribe to a paid plan first before using Explainpaper's Chat features such as summarizing. However, its alternative, UPDF AI, provides a free trial after subscription, allowing you to summarize and use all its features. One can cancel their subscription at any time.
  • It can only import PDF files and does not support other file formats. To import and explain other documents such as Word and Excel, you have to find and try another tool.
  • Users cannot highlight text and have them saved.
  • One cannot edit the paper or make notes separately. Users have to access the web app every time to use it. There is no desktop app. It doesn't offer additional features such as translating content or re-writing it.

Explainpaper is definitely a very useful tool for students, teachers, and researchers especially for understanding complex papers and getting clear-cut explanations. However, there are many disadvantages to it and this can limit users from effectively using this AI tool.

This is where UPDF AI comes out on top of being more than just an explanation tool. It is a tool that can be part of your daily work system.
