How to Create a Product Feature Comparison GPT

Updated on:
April 6, 2026

Use this interactive demo to learn how to create a product feature comparison tool with ChatGPT.

‍

‍

It is very easy to create a product feature comparison GPT. Here’s a short tutorial on how to do it:

‍

  1. On ChatGPT's main interface, go to the left-side panel and click 'Explore GPTs'.
  2. Click 'Create' at the top-right corner to get started.
  3. Following that, switch the tab from Create to 'Configure'.
  4. Set a distinctive display photo that represents your product feature comparison GPT. Simply click the 'Add' icon and pick the specific image file you wish to use.
  5. Subsequently, assign a unique GPT 'Name' and 'Description'. Enter the details into their respective input fields.
  6. Tap the 'Instructions' input field, then write a comprehensive description that covers the purpose, behavior, function, and capability of the product feature comparison GPT you wish to create.
  7. Add a few text prompt examples related to product feature comparison. Type them one by one into the 'Conversation Starters' input field.
  8. You can provide an additional source of information from external references. To do that, scroll down to the Knowledge section and click 'Upload Files'. Import the documents that contain the data you want to use.
  9. Browse the Capabilities section, then tick the checkbox beside the GPT functions you wish to enable. At the same time, you configure several Actions if you intend to integrate your product feature comparison GPT with third-party tools.
  10. Once done, navigate to the Preview Area and test out your product feature comparison GPT for the first time. Enter a text prompt into the provided input box and then click 'Submit'.
  11. Review the initial performance of your custom GPT. If you're satisfied with the quality of its product feature comparison, click 'Create' at the top-right corner.
  12. Specify your preferred access configuration, then click 'Save' to proceed.
  13. After completing these steps, your product feature comparison GPT will be created and published.

📌 Why this matters

Creating a custom product feature comparison GPT transforms how you evaluate purchasing decisions and advise others. Instead of manually researching specs across multiple sources, you get instant, structured comparisons tailored to your specific needs.

The real advantage emerges when you upload proprietary data like internal product sheets, competitor analysis, or industry reports. This creates a personalized knowledge base that combines public information with your unique insights, enabling comparisons that reflect your actual priorities and constraints rather than generic feature lists.
