Summarize PDFs with ChatGPT – Step by Step Guide

If you want to summarize your PDFs using ChatGPT, there are a few steps you need to complete. Since ChatGPT does not support PDF input, you must first convert your PDF file to text. 

Second, to get optimal summaries, you should break your PDF into sections of around 1000 words each. You should then number each section and summarize them using ChatGPT. For a high-quality summary, make sure you type the correct prompts in ChatGPT; you can check out our ChatGPT prompt guide.

The third step is to combine the summaries you have gotten and re-summarize them using ChatGPT. Thus, you can get the critical information of each section in the final output. That's all, now you know how to summarize PDFs with ChatGPT.

How do you summarize a long document with ChatGPT?

When using ChatGPT with the GPT-4 model, it is possible to summarize PDFs that are up to 25,000 words in length. However, it's worth noting that when the GPT-4 model was first announced, some users claimed that it could even handle inputs of up to 30,000 words. Over time, OpenAI decided to reduce the input character limit of the GPT-4 model to 20,000. In fact, some users report experiencing problematic output even with inputs of only 15,000 characters when using the GPT-4 model.

If you want to use ChatGPT to summarize lengthy documents, you will need to follow the method outlined in the previous section of this article. It involves dividing the PDF into sections, summarizing each section, and then combining these summaries before finally summarizing them again with ChatGPT. 

However, if you find this process too clunky, we recommend using alternative AI tools such as ZenoChat. With ZenoChat, you can quickly and efficiently summarize your PDFs without having to repeat these tedious steps.

Can ChatGPT rewrite a PDF file?

Although ChatGPT cannot directly rewrite PDF files as it is only a language model, it can help you rewrite texts after converting PDFs to text. After converting your PDF files into text, simply copy and paste them into ChatGPT and give a prompt such as “Rewrite the following text: [input].”

Advantages of Summarizing PDF with AI Chatbots

If you're tired of poring over lengthy PDFs in search of the information you need, using AI chatbots to summarize them can be an excellent solution. There are several benefits to using AI to summarize PDFs, such as increased efficiency and accuracy.

Time Efficiency

The most critical advantage of summarizing PDFs with AI chatbots is that you save time. Because every minute is valuable, you can use AI chatbots to get a summary of PDFs and focus on important information instead of wasting your time on long reading sessions. As an example, consider a 100-page PDF document. Reading such a document in its entirety could easily take upwards of 50 minutes or more. However, by using AI chatbots to summarize it, you can get a condensed version of the document that can be read in just a few minutes.

Streamline Workload

If you're a student doing research for an essay or project, using AI chatbots to summarize PDFs can be an excellent way to increase your productivity and streamline your workflow. By using these tools, you can quickly obtain summaries of lengthy PDF documents, increasing the amount of information you can collect in a shorter amount of time.

Easy to Use

One of the great advantages of using AI chatbots to summarize PDFs is that you don't need to have any technical background or advanced coding skills to use them effectively. All you need to do is enter the PDF you want to summarize into the chatbot and provide simple prompts or questions. It makes AI chatbots accessible to a wide range of users, regardless of their technical expertise or prior experience with coding.
