What is a GPT-3 Python Script?

GPT-3 is a state-of-the-art language processing model that can generate human-like text, perform language translations, answer questions and carry out various other language-related tasks.

A GPT-3 Python script is a piece of code which can access the GPT-3 API capability utilizing Python programming language. 

By getting an API key for the GPT-3 model and installing the OpenAI Python library, the script can be used to request the GPT-3 AI and obtain the output from the model. 

There are a number of beneficial tasks obtained from using a GPT-3 Python script, such as efficiency, customizability, and scalability due to the model’s power and wide range of abilities. 

Therefore, by taking the advantages of the GPT-3 model, complex language tasks can be completed quickly and with minimal effort.

How to summarize pdf files with GTP-3 and Python

To summarize a PDF file with a GPT-3 Python script, I have created this step-by-step process. If you follow these 10 steps, you should be able to summarize and create content from PDF files that are over 70,000 words long. Here are the 10 steps:

Step 1: Convert the PDF file into a text file using a Python script

The Python script is the first step to processing the PDF file and preparing it to be summarized effectively by GPT-3. 

It reads the PDF file’s data and transfers it into plain text that can be more easily understood. Depending on the size of the file, the script will take a certain amount of time to run, depending on the size of the file.

Step 2: Slice the 70,000 + words into chunks

Once the PDF file has been converted into a text file, the script is used to cut the text into reasonable chunks. These chunks should be small enough for the GPT-3 to be able to process without running out of resources, but also reasonable for improving readability. Splitting the text into appropriate chunks will help GPT-3 generate better summaries.


Step 3: Summarize each of the chunks

With the chunks created, the Python script is used to summarize each of the chunks. This speeds up the process of summarizing the full text as it reduces the amount of text that needs to be processed by the GPT-3 model. 

Each of the chunks is given their own summary and then merged into one summary.

Step 4: Merge all of the chunks into one text file

Once all of the chunks have been summarized, they are then merged into one file. This merged file contains all of the summaries of each of the chunks, making it easier for the GPT-3 to process them in an organized way.

Step 5: Write a new summary from the merged chunks of text

This new summary from the merged chunks effectively reduces the amount of text in the PDF, making it easier for GPT-3 to process. This summary is written by the Python script and is more digestible than the original text.

Step 6: Generate key notes from the summary

Once the GPT- 3 summary is written, research key notes are extracted from it. These notes are then used as a basis for the step-by-step guide as well as the blog post and Midjourney prompts. This allows GPT-3 to generate a more personalized and tailored message to each user.

Step 7: Create a step-by-step guide from the key notes

The key notes are then used to generate a step-by-step guide which gives the reader an easy read reminding them of the key notes from the book. This makes it easier for them to digest the material and apply it practically in their day-to-day life.

Step 8: Summarize the notes into the bare essentials of the book

The Python script also takes the summarized notes and reduces it down to the β€œbare essentials”. This is the most concise version of the book’s contents, allowing the reader to get a high-level overview of the book without overly consuming their time or energy.

Step 9: Write a blog post from the notes 

The blog post is written by taking the notes and expanding on them. This allows the reader to get an in-depth view of the book as well as a comprehensive overview of the topics discussed.

Step 10: Generate some mid-journey prompts from the notes

Finally, the Python script is used to generate some mid-journey prompts from the notes. These prompts are used to help the user keep motivated along the path of deep work and focus effectively on the task at hand.



In conclusion, using GPT-3 and Python is a powerful and efficient way to summarize long PDF documents for research or other use cases. 

By following our step-by-step guide, you can take advantage of the capabilities of the GPT-3 model to quickly and easily generate summaries, key notes, step-by-step guides, and even Midjourney prompts. 

Whether you’re looking to save time, customize your summaries, or scale your summarization process, GPT-3 and Python provide a wide range of options to meet your needs. 

So why wait? Try out this process for yourself and see just how powerful and useful GPT-3 and Python can be for summarizing PDFs.


  1. hi, your stuff is great.thanks. do you have more detailed, step-by-step guides on how to make the various GPT-3 Python scrips mentioned? I am really bad at programming (python) and need detailed guidance. Is that something you have/do? Is it behind a paywall?

  2. Hi!

    I would also be keen to see a more detailed version of how to code this! Any further guidance would be much appreciated!

    Thanks a lot !

  3. Hello!

    Thank you for your article – exactly the topic I was looking for. I have many (not too many) PDFs that contain text, layout, images and colors. And some of these are more or less spieling to customers. I was trying to summarize them and understand where they are similar or different. I hope GOT-3 can help with the text part. Would you mind sharing some code how to do that? Also… any idea how I can combine summarization of text, color and image design into one? Thank you so much for your guidance!

  4. interesting update… i would love to test this out can i ask pls is this opensource are you planning to create something big with this?

  5. Hi Kristian,

    This is amazing! Since ChatGPT’s database lacks so many books I need for school, your method is a lifesaver!

    Just one small problem: I’m a complete beginner when it comes to Python (and coding in general)…

    Could you also please send me a more detailed, step-by-step guides on how to make the various GPT-3 Python scrips mentioned?

    Thank you so much!

  27. Hey Kristian
    I like your work. Could you send me the python script for summarizing a PDF file? I am just getting started.
    Thank you.

  28. I love your script – but as a new user of Python, I’m having trouble getting it to execute. Specifically, even though I’ve renamed my PDF to match what’s in the script, when I execute the script, it says it cannot find the file. Is there a specific place I’m supposed to store the PDF for the script to be able to locate it? I get the same issue when I try to use it on Colab ( Any help would be appreciated!!
