Before diving into the creation process, it's crucial to understand what custom GPTs are. Unlike standard models, these AI chatbots can be specialized for unique tasks - from handling customer service inquiries to assisting with educational content.

Creating Your Custom AI Chatbot: A Visual Tutorial Using "Marketing Mentor" as an Example

When you're building a custom GPT chatbot, the process is as much about the journey as it is about the destination. Here's a step-by-step account based on the visuals provided.

Step 1: Getting Started with the GPT Builder

  • Open the GPT Builder, and you'll be greeted with a friendly message offering to help you build a new GPT.
  • The interface is split into two main areas: the setup area on the left and a preview section on the right.

Step 2: Naming and Describing Your Custom GPT Chatbot

  • In the 'Name' field, I entered "Marketing Mentor" to reflect the chatbot's purpose.
  • For the 'Description', I typed "A friendly guide for small business owners seeking basic marketing advice." This gives potential users a clear idea of what the chatbot does.
  • Use GPT Builder: You can also skip the hard work and give instructions to the GPT Builder and it will create it for you. Just specify the bot's task, the target audience and which features it should use.

Step 3: Setting Up Instructions for Your Custom GPT

  • In the 'Instructions' box, I detailed the chatbot's function: "This GPT is designed to assist small business owners with basic marketing advice. It leverages the web browsing feature to access the latest marketing trends and data, ensuring it provides up-to-date and relevant information."
  • I made sure to emphasize the user-friendly aspect and the reliance on publicly available data for privacy concerns.
  • Remember the GPT Builder can always guide you through the process with ease.

Step 4: Adding Conversation Starters to Your Custom GPT

  • Under 'Conversation starters', I included questions like "How can I improve my business's online presence?" These act as prompts for users and help the chatbot understand the kind of information it needs to provide.
  • If you are not sure, you can ask GPT builder to complete conversation starters for you.

Step 5: Selecting Capabilities for Your Custom AI Chatbot

  • In the 'Capabilities' section, I checked 'Web Browsing' to enable the chatbot to fetch current marketing data.
  • I skipped 'DALL-E Image Generation' ' as it's not necessary for a marketing advice chatbot.
  • You can also input your API key to let the chatbot access your data from external sources, however for this example we are keeping it simple.

Step 6: Customizing the AI Chatbot's Image

  • The builder suggested an image, but I wanted something more aligned with my chatbot's theme. So, I asked to revise the image to better reflect the concept of marketing mentorship.
  • It generated this owl as you can see below, with book titled as 'Marketing'. This works for me, so without any work on my part the GPT Builder updated the chatbot's image automatically.
  • By clicking on the picture of your custom AI chatbot, you can always choose to "Upload Photo" if you want to customize it more with your own graphics. Otherwise, you can just use DALL-E image generator for the task.

Step 7: Finalizing Your GPT

  • After filling out the necessary fields and tailoring the chatbot's abilities, I clicked on the 'Save' button in the preview area to secure my progress.
  • You can now make your AI Chatbot public, or make it private only for your team internally.

Step 8: Testing and Iteration

  • With "Marketing Mentor" created, I would test it by uploading relevant documents or asking marketing-related questions to see how it responds.
  • Depending on the results, I'd go back to the 'Configure' tab to make adjustments, continuously improving the chatbot's performance.
  • So far, I'm satisfied with results that you can see below.

  • You can always keep the chatbot private or give it to people with a link to test it out until you're fully satisfied with your creation.
