10 Best Tools for Summarizing PDFs

PDF is one of the best formats to read documents because it is stable for reading as well as for editing. Whether it is journals, papers, legal documents, magazines, books, or other publications, they are mostly published in PDF format. Many PDF documents are long-form or multi-page documents, particularly legal documents, which make readers take time to comprehend their meaning. In the AI era, we can simplify this by using AI summarization tools for PDFs. In this article, we will guide you to find the 10 best tools for summarizing PDFs according to their capabilities and best features. 

What is an AI summary? 

Before moving forward to the best PDF summarization tool, let me briefly explain AI PDF summarization in short. AI summary is basically a summarization of text, audio, and even video into succinct and easier-to-understand language using artificial intelligence (AI). This technology allows AI to paraphrase and analyze the meaning of long-form documents that oftentimes require a lot of effort. 

To get to know more about AI summarization, there are two types of AI summarization: extractive and abstractive. Here is an explanation of both types of AI summarization.

• Extractive summarization: This type of summarization focuses on extracting key sentences or phrases from some source material to generate a concise summary. 
• Abstractive summarization: This type of summarization enables AI to generate entirely new words from source of materials into a summary. 

Basically, the difference between extractive and abstractive summarization lies in the ability of AI to summarize. Extractive summarization not able to deeply understand the source materials. Meanwhile, abstractive summarization needs to understand the meaning and rewrite it into new phrases. 

Why do people look at AI PDF summarization tools? 

As we mentioned in the introduction, people look at AI PDF summarization tools as an assistant to simplify the process of understanding the key points of a PDF document, particularly long-form and dense documents such as legal documents. Instead of reading the whole text, an AI summarization tool will help you to directly give the key points and key takeaways in seconds. Here is the explanation of why people turn to AI PDF summarization tools. 

• Time savings: By using AI PDF summarization, you can summarize multiple pages of long-form documents into concise briefs that are easier to understand. This summarization is definitely less time-consuming when it comes to finding out the meaning of the core information in the documents. 
• Enhance understanding: AI summarization can help users to highlight the key points, including discussion, evidence, and conclusion, within the long-form text. So, you can easily comprehend the whole point before reading the full text. 
• Improve decision-making process: AI summarization helps users to grasp the relevant information they need. If the information can be understood quickly, then business, legal, or research decisions can be made accordingly. 
• Reduce human errors: We know that humans can make errors, especially when they need to read long-form documents in PDF. Then AI summarization can help to minimize errors and check if there are any mistakes. However, you need to understand that AI is trained and built by humans, which means they also can make some errors. 

What are the criteria to assess the best tool for summarizing PDFs?

The best tool for summarizing PDFs does not solely depend on the performance of summarization. You also need to consider their offerings as a whole to assess whether the tools are the most suitable for your assistant. In order to find the best tool for summarizing PDFs, we have assembled criteria below. 

• Summary accuracy and quality: The first thing you should notice to find the best tool for summarizing PDFs is definitely the quality. This means that you need to check the summary accuracy, citations or references, as well as the structure of the recap of PDF documents. 
• Document handling capacity: When it comes to choosing the best tool for summarizing PDFs, we need to check how many PDF pages or words it can scan and the maximum upload file size. In addition, you need to know whether the tool is able to extract images using OCR and preserve tables. 
• Promote privacy and compliance: Summarization means that the information can be retained within the app storage. Therefore, if you are regularly handling sensitive data, then you need to focus on the app that promotes users’ privacy and compliance with data security. 
• Cost effectiveness: Cost is one of the most critical criteria to choose the best tool for summarizing PDFs. Many tools provide the best AI-powered summarization at no cost or for free, but with no guarantee of privacy and security. Some tools provide paid plans and promote more security by not using your uploaded data in their storage, as well as other advanced features.
