Here's the simplest way to do this without overcomplicating it.
Step 1: Generate Your Knowledge Base
First, run the prompt you built earlier. (If you haven't built your knowledge base yet, go here to get the reverse prompting system). Paste it into ChatGPT or Gemini and go through the full interview. Take your time and answer honestly. This part will take the longest, and that's normal. You're building the foundation here.
When it finishes, it will output multiple sections that are formatted like text files. You'll see things like:
- Identity.txt
- Skills.txt
- Business.txt
- Offers.txt
- Customers.txt
- Problems.txt
- Goals.txt
- Constraints.txt
- Operations.txt
- DecisionMaking.txt
- CommunicationStyle.txt
- Summary.txt
- CUSTOM_GPT_INSTRUCTIONS.txt
Step 2: Save Your Files Locally
Now you need to save these.
Create a folder on your desktop. Name it something simple like "My AI Brain" or "Custom GPT Files." You want it somewhere easy to find without thinking.
Then go back to ChatGPT. One by one, copy each section and paste it into a new text file on your computer. Name each file exactly what it says. For example, copy the Identity section and save it as Identity.txt. Do that for every file, especially the CUSTOM_GPT_INSTRUCTIONS.txt file. That one matters most.
Once everything is saved, you're done with the hard part.
Step 3: Start the GPT Builder
Now you're going to build your Custom GPT.
Open ChatGPT. On the left side, click "Explore GPTs," then click "Create."
You'll land on a screen with a builder. Ignore the chat-style builder. Go to the "Configure" tab. Now you'll see a few fields.
Step 4: Set the Instructions
There's a box labeled "Instructions." This is where your system behavior lives.
Open your CUSTOM_GPT_INSTRUCTIONS.txt file. Copy everything inside it. Paste it directly into the Instructions box.
Step 5: Upload Your Knowledge Base
Next, look for the section where you can upload files. This is usually labeled "Knowledge" or "Files."
Upload the rest of your text files:
- Identity.txt
- Skills.txt
- Business.txt
- Goals.txt
- Problems.txt
- Constraints.txt
- and any others you created
These files give your GPT context. This is what makes it understand you instead of guessing.
Step 6: Name and Save
Now give your GPT a name. Something simple like "My Business AI" or "Operator AI."
You can add a description if you want, but it's optional.
Click save.
That's it.
You now have a Custom GPT that actually knows who you are, what you're trying to do, and how you want it to respond.
From this point forward, you don't need to re-explain yourself every time. You can ask better questions and get better answers because the system already has context.
One last thing. If things change, update your files. This isn't a one-and-done setup. It's something you refine as you grow.
But even a rough version of this is already ahead of how most people are using AI.
