5 Best PDF Summarizers for 2024

I carefully explored and experienced all of these PDF summarizers before recommending them to you. Now, if you're a student, you'll find all these features useful, depending on how you want to use them. Whether you need to quickly grasp the main points of lengthy reports for studying or research purposes, or if you're looking to extract key insights from dense academic texts, WPS AI's summarization capabilities are something that I heavily rely on. The precise keyword extraction is especially handy when you need to focus your analysis on specific topics or themes within a document. And don't overlook the contextual understanding feature—it adds depth to your analysis by considering the broader context of the content you're summarizing.

WPS AI PDF – Secure and Versatile

WPS AI PDF integrates seamlessly with the writer and the PDF tool. When it comes to summarizing, there is no tool like WPS AI PDF that does it better. The PDF features themselves are such a great asset. You can open and edit PDFs easily, and then the AI integration enhances the reading experience by providing summaries that match your needs. You can add prompts to extract particular information, so if you want specific info from a report, you can get it. You can get a summary exactly how you want; you just need to know how to form your prompts.


One of the standout features is its reliability and data security. Unlike online summarizing tools that risk leaking private information, WPS AI PDF ensures your data remains secure. The integration with other office tools boosts productivity significantly. For example, if the summary from WPS AI sparks inspiration for your writing, you can effortlessly switch to WPS Writer, Spreadsheet, or Slides to jot down your thoughts.

Additionally, WPS AI PDF offers access to ChatGPT, allowing users to make inquiries based on the PDF document. This feature adds another layer of functionality, making it a comprehensive tool for managing and summarizing PDF content.

TLDR This — Detailed Summary with Highlights

There's quite a selection of summarizers out there, considering the abundance of information we're surrounded by. In this fast-paced era, staying updated is crucial, yet time is a valuable asset we must respect. Among these summarizers, TLDR stands out remarkably. Just paste an article or input a URL, and voila! You get an instant summary. What's more, you have two handy options: a brief, concise summary or a detailed breakdown of each section. And if that's not enough, there's even an AI human-like version available for you to choose from.


Hypotenuse AI – Combining Summary with AI Writing Tools

With so many excellent summarizing tools available, Hypotenuse AI stands out for its simplicity and readability. It offers two summary format options: paragraph or bullet points, making it versatile for different preferences. As for its capabilities, it primarily functions as an AI writing assistant, facilitating document digestion and writing simultaneously. However, it lacks additional features to extract information or customize the summary to your preferred language style.

Large PDF Summarizer – For Long Documents

Large PDF Summarizer lives up to its name by specializing in handling extensive PDF documents, accommodating up to 1,500 pages or 300K words. This feature makes it particularly useful, especially when dealing with lengthy reports. I appreciate being able to directly upload the file to the summarizing app and receive an instant summary. However, one limitation is the lack of control over the length of the summary.

Resoomer – Customizable Summary

Resoomer is a website where you can input your text by simply copy-pasting it, and it's completely free to use. It offers various options for summarization, including assisted, automatic, manual, optimized, and text analysis. What sets it apart is its ability to maintain the vocabulary and writing style of the original text.


Essentially, it condenses the article while preserving its essence, providing more of a condensed version rather than a traditional summary. This tool is particularly useful if you prefer to write the summary yourself and want to retain the author's exact words. Additionally, it allows you to control the level of brevity you desire, giving you flexibility in how concise you want the summary to be.

During the trial, you'll have access to even more functionalities to fully experience WPS AI's capabilities, although with some limitations. If you're ready to unlock the full potential, you can upgrade to the premium version for $29.99 a year or opt for the professional version at $80 a year.

Streamline Your Reading with WPS AI PDF

PDF summarizers are eventually important for everybody. If you don't use them yet, you should consider it, because time is precious, and knowing how to respect it means not spending undue time on lengthy articles when you could allocate that time elsewhere.

WPS AI is my preferred choice because it helps me navigate through the PDFs I need to read, ensuring I don't miss out on crucial information.
