• Comments Off on Can Chat GPT summarize a PDF?

The quick answer is: Yes, but you have to copy the text into ChatGPT.

There’s a few more nuances to it, so let’s discuss this in a bit more detail.

Unfortunately there’s not direct answer to “Can Chat GPT summarize a PDF”, because you can’t upload files to ChatGPT. But if you have long PDFs that you need to go through for work or research summarizing a PDF file would save you a lot of time. There’s a few workarounds to make this happen. Sometimes its as easy as copying the text into ChatGPT and asking it to summarize the PDF. But if you have PDF files with images or text that isn’t copyable, then it gets a bit more difficult. So let’s have a look at this in a bit more detail.

How to Use ChatGPT for Summarizing PDFs

Here’s a simplified step-by-step guide on how to use ChatGPT to summarize a (very long) PDF:

Step 1: Get Your PDF Ready

Find the digital version of your desired PDF. Make sure that the text is selectable and you can copy and paste it. This is really important since otherwise you will first have to find a tool to convert the PDF into text. Most likely this will be done by a OCR software tool.

Here’s how you copy the text of your PDF on MacOS. The process works almost identical on Window.

Step 2: Open ChatGPT

Visit chat.openai.com and sign in. Note that you will achieve better results with the paid version of ChatGPT since it uses the GPT 4 model.

Step 3: Ask ChatGPT to write a summary

ChatGPT Prompt Interface

ChatGPT will now provide you with a summary for your PDF. If you feel like the summary is too short or is missing an important piece of information then you can follow up with a prompt like the following:

“The summary is too short can you extend it to 750 words”

“The summary is lacking information on the financial data of the company, can you add that”

You can almost treat ChatGPT as a normal person, if you’re not happy with the results simply give it some feedback.

Creating the Right Prompt for ChatGPT

When you’re summarizing a PDF using ChatGPT its important to use the write prompt. Let’s look a bit into which summarization prompts make the most sense and what pitfalls there are.

ChatGPT can produce very different results for a PDF summary depending on the prompt you use. Here are some tips when creating a prompt to summarize PDFs:

  1. Length Matters: If you want a concise summary, guide ChatGPT on the desired length. Example: “Provide a summary of about 100 words.”
  2. Be Specific: If your PDF covers a broad topic and you’re only interested in certain parts, direct ChatGPT accordingly. For instance, “Provide a summary on the financial aspects of the text below.”

ChatGPT Limitations when Summarizing PDFs

While ChatGPT is great, it’s still evolving. Here are some things to keep in mind when using ChatGPT to summarize a PDF:

  • Token Restrictions: The current version has a token limit which translates to a certain number of words. Most PDFs should fit, but hefty PDF documents might not work. In those cases as a workaround you can split the text in multiple parts and then use ChatGPT for each part to summarize the text.
  • Accuracy Concerns: ChatGPT can occasionally deliver answers that sound right but aren’t. Always double-check.
  • The Oversimplification Trap: ChatGPT can sometimes skip over nuances. So, while it’s great for quick insights, for critical tasks, you’d want to go through the entire material. Additionally we always recommend you to add a more specific prompt to make sure ChatGPT pays attention to details that matter to you.
  • Only Text is used to summarize: When you use ChatGPT to create a summary for your PDF then it can only use the text you’ve copied. Any graphics, diagrams, charts or other media content is unfortunately not going to be part of the summary.
