Use this interactive demo to learn how to build and publish a custom content style guide GPT in ChatGPT.

Quick summary

A custom content style guide GPT is a ChatGPT GPT you configure with a name, instructions, knowledge files, and conversation starters so it enforces your brand's writing rules on demand. You can create, configure, and publish one directly inside ChatGPT's GPT builder without any coding.


Steps

  1. On ChatGPT's main interface, open the left-side panel and click Explore GPTs.
  2. Tap Create at the top-right corner to start building a new GPT.
  3. Switch the tab from Create to Configure to access the full setup options.
  4. Tap the Add icon to upload a distinctive display photo that represents your content style guide GPT.
  5. Enter a unique GPT Name and Description into their respective input fields.
  6. Click the Instructions field and write a comprehensive description covering the GPT's profile, behavior, function, and capabilities.
  7. Type prompt examples one by one into the Conversation Starters field to guide users through their first interaction.
  8. If needed, click Upload Files under Knowledge to import reference documents for the GPT to draw from.
  9. Review the Capabilities section and tick the checkboxes for the GPT functions you want to enable; optionally configure Actions to integrate with third-party tools.
  10. Go to the Preview Area, type a prompt into the input box, and click Submit to test your content style guide GPT.
  11. If satisfied with the output quality, click Create at the top-right corner.
  12. Choose your preferred access configuration and click Save.
  13. Your content style guide GPT is now created and published and ready for use.

📌 Why this matters

Building a custom content style guide GPT in ChatGPT gives content teams an always-available AI assistant that enforces brand voice, tone, and writing standards consistently across every piece of content. Instead of manually reviewing brand guidelines before each writing task, writers can query the GPT directly and get on-brand guidance in seconds. This reduces editorial review time, accelerates content production, and ensures consistency whether a team scales from two writers to two hundred. For organizations investing in AI-powered content workflows, a dedicated style guide GPT is one of the fastest ways to embed brand governance directly into the writing process.
