How to Create a Content Topic Generator GPT

Updated on:
May 12, 2026
By:
Madhav Bhandari
Use this interactive demo to learn how to build and publish a custom content topic generator GPT.

Quick summary

A custom GPT built for content topic generation lets you automate idea creation with a tailored AI model configured directly inside ChatGPT. This step-by-step guide covers everything from naming your GPT to setting capabilities, uploading knowledge files, and publishing it for use.


Steps

  1. On ChatGPT's main interface, navigate to the left-side panel and click 'Explore GPTs'.
  2. Tap 'Create' at the top-right corner to begin building a new custom GPT.
  3. Switch the tab from Create to 'Configure' to access the full setup options.
  4. Click the 'Add' icon to upload a display photo that represents your content topic generator GPT.
  5. Enter a unique GPT Name and Description into their respective input fields so users can identify it easily.
  6. Click the 'Instructions' input field and write a comprehensive description covering the GPT's profile, behavior, function, and capability.
  7. Add text prompt examples related to content topic generation by typing them individually into the 'Conversation Starters' field.
  8. Click 'Upload Files' under the Knowledge section to import any external reference documents you want the GPT to use.
  9. Browse the Capabilities section and tick checkboxes for the GPT functions you want to enable, and optionally configure Actions to connect with third-party apps.
  10. Navigate to the Preview Area, type a test prompt into the input box, and click 'Submit' to evaluate your GPT's output.
  11. If satisfied with the performance, click 'Create' at the top-right corner to proceed.
  12. Choose your preferred access configuration, then tap 'Save' to finalize the settings.
  13. Your content topic generator GPT is now created and published and ready for use.

📌 Why this matters

Building a custom content topic generator GPT in ChatGPT allows content teams and marketers to automate the ideation process with a purpose-built AI model tailored to their specific niche, audience, and brand voice. Unlike generic AI prompts, a configured custom GPT retains consistent instructions, conversation starters, and knowledge files — making it a reusable, scalable tool for ongoing content planning. This reduces the time spent brainstorming topics from scratch and ensures every suggestion aligns with predefined content strategy parameters. For teams publishing at high volume, a dedicated content topic GPT directly improves editorial efficiency and output consistency.
