How To Write a DND Campaign With ChatGPT (2026 Guide)

Beginner Advice / By

Creating a Dungeons & Dragons (D&D) campaign is fun but it can also be time-consuming and challenging.

Enter ChatGPT. It has come a long way since this guide first went up, and the prompts below still work in the current version.

The biggest upgrade since this guide was first written is that you no longer have to start from a blank chat. ChatGPT now has Projects, which let you keep your world notes, session recaps and instructions in one place so every new chat starts with your setting already loaded. Free accounts get a small number of files per project and paid plans get more. Drop in your campaign notes and say “stay consistent with these notes” before you ask for anything new.

Here’s how to write a DND campaign with ChatGPT:

Write a DND campaign with ChatGPT by prompting the AI tool to create settings, themes, BBEGs, NPCs, PCs, plotlines, encounters, rewards, consequences, campaign milestones, and session preparation. Fine-tune prompts and iterate on ideas to achieve engaging and unique campaigns.

In this article, we’ll walk you through the process of crafting a D&D campaign using ChatGPT, providing example prompts for each major element.

Treat any stat block or rules ruling from an AI as a first draft. It can sound confident and still get a number wrong, mix up the 2014 and 2024 versions of a rule, or invent a spell that does not exist. Tell it which edition you play, name the monster or spell you want it to base the stats on, and check the final numbers against the Monster Manual or D&D Beyond before the session.

ChatGPT can assist you in preparing for your sessions by generating adventure hooks, scene descriptions, encounter maps, and more.

After each session, paste in your rough notes and ask for a one-page recap, a list of open threads, and three hooks that follow from what the players did. Then use that recap as the starting point for next week’s prep. It takes five minutes and keeps your NPCs and plot threads from drifting.

Notes and Reminders

ChatGPT can help you create notes and reminders to keep track of important information and ensure your sessions run smoothly.

Example prompt:

Generate a list of important notes and reminders for a Dungeon Master to keep in mind during a D&D session.

Collaboration and Iteration

Working with ChatGPT can be an iterative process, and refining your ideas and content is an essential part of creating a great D&D campaign.

Here are some tips on how to collaborate effectively with ChatGPT.

Final Thoughts: How To Write a DND Campaign With ChatGPT

Use the example prompts in this article to spark your planning, check any rules it gives you against the books, and enjoy a memorable D&D experience for you and your players.

Using AI to prep your own game at home is one thing. Selling or publishing the output is another. Wizards of the Coast has said it does not allow generative AI in its artwork, and the DMs Guild policy, last updated in May 2026, says community content cannot include AI-generated material. If you plan to publish what you make, check the current policy first. And whichever chatbot you use, do not paste in your players’ personal details.

ChatGPT is not the only option. Claude, Gemini and Copilot can all do this job, and the prompts here work in any of them.
