How to use ChatGPT to analyze PDFs (and more) for free

Even though OpenAI allows you to access ChatGPT without logging in, you will need to sign in to your account to use GPT-4o and its advanced features, including Browse, Vision, data analysis, file uploads, and GPTs.

If you have never created a ChatGPT account, you can easily do so from the sign-in page or login with your existing Google or Microsoft account. I opted for the latter option, so I don’t have to memorize another username and password. 

Once you sign in, you will be brought to the ChatGPT interface. Next to the textbox where you would typically insert text to start chatting, you will see a little paper clip icon. When you click that, you will have several options: Connect to Google Drive, Connect to Microsoft OneDrive, or Upload from a computer.

Select the best option for where your document lives. Since I typically upload a document I just downloaded, I always opt for upload from my computer. Then, you can click on the PDF you want assistance with. For this example, I am using a PDF of one of my ZDNET articles.  

Once you upload the PDF, you can accompany it with a text query that indicates what you’d like ChatGPT to do. You can make these prompts as adventurous or simple as you’d like. I kept it simple and asked for a summary: “Can you summarize what this article is about?”

As you can see in the photo below, I immediately got a comprehensive four-sentence summary, and since I wrote the article, I can verify that it was accurate. 

You can also elicit the chatbot’s help for more complex tasks. For example, you could ask the chatbot to “Take out the action items found in this PDF, place them in bullet points, and format them into an email addressed to my boss.”

Overall, using ChatGPT to help parse through dense PDFs can help you save time and sift through long-winded paragraphs. Of course, always make sure to check ChatGPT’s work for hallucinations, just in case. If you want to explore more document-summarizing tools, stay tuned for similar capabilities coming to Apple OS later this year.
