Using AI to play Role Playing Games – Building tools to play Dungeons and Dragons is playing D&D…?
I wanted to see how much time I spend playing D&D with AI versus building the tooling for playing D&D with AI. Charted across 4,245 conversations back to 2023: harness building goes from 5% to 53%. The cobbler’s curse – you love making shoes so much you never walk around in them.

A totally custom, one-off D&D battle map, made by ChatGPT and prompted by Claude
Here’s another, totally custom and one-off battle-map AI made for me: This was just a random encounter in a D&D adventure I was doing with solo role-playing with AI (Claude). I asked it to generate a prompt to give to ChatGPT to generate the battle-map, and the results were amazing. Here’s the prompt that generated…

How to use AI for solo roleplaying with Dungeons & Dragons
Here’s my talk from AI for the Rest of Us: What the goblins can teach us about enterprise AI. // I’ve learned what agentic AI is by fighting goblins, talking with trolls, and buy custom made boots from gnomes. After a few years of playing solo D&D with ChatGPT, Claude, Gemini, etc., playing the role…

Using ChatGPT image generation to make isomorphic D&D maps
With a little prompt craft, you can get some good regional maps out of ChatGPT. Here is the original photo I took on a flight from London for Amsterdam: The prompt I used: Use this image to determine the layout of a D&D map in the style of Dungeons and Dragons adventures and maps. Pay…

“Touch of Water,” from Uncaged, volume 2
I solo played “Touch of Water” last night. It’s a good representation of the adventures in the Uncaged series.1 Claude did a good job adapting it my campaign setting and evolving the story. The rusalka is a good monster – it’d make a good Eryines-like creature for Auril the Frostmaiden. You can recast Auril regionally,…

When should a Claude Skill use code versus just a SKILL.md?
Here are some thoughts after a week of using Claude Skills. JasonJ in the SDT Slack says: I’d tl;dr Claude CLI skills as “low/no/english code MCPs’”. Seems helpful in the way that local utility scripts are today. That is a good way of putting it. I haven’t done heavy experimenting, but I think there’s a…

Using AI to make quick D&D battle maps in Claude
You can ask Claude to make you quick D&D maps. This is useful if you’re solo roleplaying with it. As you create encounters together, having a map is good for tracking complicated situations and getting spatial awareness. The only thing is you’re making very crude vector maps (SVGs), not the more realistic ones that ChatGPT…

Battle Maps for The Dying Unicorn adventure
Maps for The Dying Unicorn side adventure, which did not have any, being a small adventure. I like very large battle maps maps rather than the standard 40×30 or whatever. Ranged with long bows and the like aren’t too fun on tiny maps. Plus, if you end up playing a cat and mouse game, you…

How to make MCP Prompts in Java with Spring AI – Coding Model Context Protocol Prompts – Solo roleplaying D&D with agentic AI, #04
Let’s get the AI to build D&D adventures for us with a Model Context Protocol Prompt. I haven’t found much value in MCP Prompts until now. What makes them excited is when you use them a “recipe” to chain together other tool calls. In this episode of my MCP programming series, I show you how…

How to create a Model Context Protocol Resource – Solo roleplaying D&D with agentic AI, #03
The AIs are good at being a Dungeon Master for Dungeons & Dragons, but their memory is limited. How can you make sure they don’t forget all that loot you just got, or ensure that cobbler back in the village remembers the type of boots you orders and paid for up front? I’ll show you…

Spy on the DM with Model Context Protocol Servers in Java – Solo roleplaying D&D with agentic AI, #02
Not only can you give more direction to the AI when you’re playing solo D&D with it, you can start to understand how it thinks. I walk through how to use MCP Server tools to enhance solo roleplaying with Claude (and ChatGPT, etc.) and how to get extra information about how the AI is thinking.…

ChatGPT is very good at making D&D battle maps
D&D battle maps are one of the funnest parts of D&D. Just looking at them is fun, finding them can be a tiny thrill, and making them is a delightful way to spend hours of time. Oh, and using them. I’ve used Midjourney to make D&D battle maps in the past, especially to make really…

Solo Roleplaying D&D: Make full character sheets for NPCs
When playing solo D&D, try making full on characters for the major NPCs. This can be more fun because (a) making characters is fun, especially higher level ones, and, (b) you get more faceted NPCs instead of just stock, one-dimensional characters. I’ve been playing through Icewind Dale: Rime of the Frostmaiden and I applied this…

ChatGPT DnD Prompt: Tuning It for Solo D&D Play
For about 7 months, I’ve been playing solo D&D with ChatGPT. I prompt ChatGPT to be the “ChatDM.” It sort of works, and at least, it’s fun enough to keep doing it and working on making it better. Here’s my most recent overview of what works and doesn’t work, based on a longer play session…

AI DnD: How to Play Solo Dungeons & Dragons with ChatGPT
Is ChatGPT good at being a Dungeons & Dragons Dungeon Master? I’ve been experimenting with this for a while now. I do this because (1) it’s fun, and, (2) it’s a good way to understand what generative AIs can actually do, how they do it, and how to work with them. They’re not as fantastic…

AI-Generated DnD Battle Maps with Midjourney
You can generate really big Dungeons & Dragons battle maps with Midjourney. It takes some iteration and tinkering, but the maps are great. I like big battle maps so that characters, NPCs, and monsters have lots of room to move around and take tactical advantage of ranged spells and attacks. While the big images are…

New prompt to get ChatGPT to Dungeon Master Solo Dungeons & Dragons
Update: here’s a newer prompt I’ve been using, plus more how to play D&D with ChatGPT. Here’s another prompt I’ve used to have ChatGPT be a dungeon master for ChatGPT. See the older one here. I think this one is probably too long. What I’ve done here is, largely, dropped any instructions on mechanics (skills…

Bootstrapping ChatGPT 3.5 and ChatGPT 4 to be a Dungeon Master for solo play in Dungeons & Dragons
I’ve been experimenting/playing a lot with ChatGPT as a Dungeon Master. I like to call this “ChatDM.” That is, I’m a player, and it DMs for me. It’s not, like, great, but it is good enough if you want to co-imagine with it. Overtime, it is a great world building co-author with you. The current…
