How I Used GPT-3 to Create My Second Brain Using AI

If you’re on the lookout for innovative ways of augmenting your productivity and streamlining your workflow, then using artificial intelligence might just be the answer you’ve been searching for. In this blog post, I’ll be sharing my personal experience of how I utilized GPT-3 – one of the most advanced AI language models – to create my second brain. Stay tuned to find out how you too can benefit from this cutting-edge technology and take your productivity game to the next level.


As the amount of information we take in every day increases, it becomes more and more challenging to keep track of important details such as dates, events, and ideas. For a long time, I struggled with this problem until I came across a video explaining how to use GPT-3 and AI to build a personal “second brain.” This video changed my life, and in this article, I will take you through the process of creating your own second brain, just like I did.

What is a Second Brain?

A second brain is a system that helps to capture and organize ideas, notes, and information that one comes across in their daily life. A second brain acts as an extension of your memory, allowing you to offload some of the information you would otherwise be forced to remember. It helps you to focus on important ideas and tasks while providing a searchable archive of information.

The Ultimate Productivity Hack

Building a second brain is vital since it creates a system that doesn’t require us to remember everything, and it allows us to concentrate on what is important. A second brain is the ultimate productivity hack, which frees you up to think of new ideas, focus on tasks at hand, and achieve your personal goals quicker.

Creating a Second Brain Using GPT-3

To create a second brain, we start by creating a journal. The journal is a place where you can take notes and jot down ideas that come to you throughout the day. Once you have a sufficient number of notes, you can then leverage GPT-3, an AI language model, to filter through the notes and create cohesive articles that contain actionable insights.

Semantic Search with Vectors

Semantic search with vectors is the critical technology behind the second brain. Vectors are algorithms that cluster words together based on their meaning. By clustering words in this way, it becomes easy to find information that is relevant, even if it’s not explicitly stated in the text. Semantic search with vectors also has the added benefit of hiding irrelevant information.

Creating a JSON Object with Embeddings

Once you have a journal filled with notes, you can convert it into a JSON object with embeddings that represent the strings. A JSON object is a data file that contains structured information about the journal notes. It can be queried using vector search, which allows you to find specific information.

Finding Events and Dates

After you have stored all your notes in the second brain, finding specific events and dates becomes a breeze. You merely enter the keyword, and the second brain will give you a list of notes that contain that keyword. It’s like having a personal search engine for all of the knowledge and information that you’ve stored.

Summarizing Recent Activities

The second brain can also summarize the past week’s activities. Instead of spending ten minutes trying to remember what you did last Wednesday, you can enter the date in the search engine, and all the relevant information will be pulled up. This feature helps alleviate the stress of keeping track of your daily routine and can help you focus on achieving your goals.

Deleting Memories from the Brain

Just as it is important to store relevant information, it is equally important to delete irrelevant information. The video on building a second brain also shows viewers how to remove memories from the digitized brain. This feature is especially useful when you want to free up space or when memories are no longer useful.

Membership for Step-by-Step Tutorials and Access to 30 Other Videos

If you are interested in creating a second brain of your own, the creators of the video also offer a membership for step-by-step tutorials on how to create your own second brain using AI and GPT-3. The membership also provides access to 30 other videos that will help you achieve maximum productivity with the second brain.


Building a second brain using GPT-3 and AI is an incredible productivity hack that allows you to focus on the things that matter while still retaining access to the information that you need. It is an easy process that involves creating a journal, using semantic search with vectors, embedding the journal notes into a JSON object, and finding information by searching for specific keywords. The second brain also has the added benefit of being able to summarize your past week’s activities and removing irrelevant information. Building a second brain is not only practical but also advantageous in achieving your personal goals.


  1. How long does it take to create a second brain using GPT-3?
    A: It can take a little time to set up the process, but once everything is in place, it should be a relatively automated process.

  2. Is creating a second brain expensive?
    A: The cost of creating a second brain is determined by the tools used. However, this video shows that you can build a second brain using free online tools.

  3. Can I use a second brain to analyze data?
    A: Yes, you can use a second brain to analyze data. Semantic search with vectors makes finding specific information simple.

  4. Can a second brain be used for group projects?
    A: Yes, a second brain can be used for group projects. Each member’s input can be stored in the second brain and searched for using semantic search with vectors.

  5. Can I create my own unique process besides the one shown in the video?
    A: Yes, you can create your own unique process. The video is a demonstration of the concept, and many people have adapted the process to meet their individual needs.
