Someone made a Raspberry Pi D&D DM cyberdeck that tracks campaigns, rolls dice, and generates NPCs

Credit: Wintaru Published Aug 19, 2026, 3:28 AM EDT Simon is a Computer Science BSc graduate who has been writing about technology since 2014, and using Windows machines since 3.1. After working for an indie game studio and acting as the family's go-to technician for all computer issues, he found his passion for writing and decided to use his skill set to write about all things tech. Since beginning his writing career, he has written for many different publications such as WorldStart, Listverse, and MakeTechEasier. However, after finding his home at MakeUseOf in February 2019, he would eventually move on to its sister site, XDA, to bring the latest and greatest in Windows, Linux, and DIY electronics.

Runs LoreKeeper with an onboard Ollama LLM, links to D&D Beyond, rolls dice, and shares info with players. The GitHub repo offers full source code if you want to try making one yourself. There's nothing like being put on the spot as a D&D dungeon master when your players ask to talk to someone you haven't made notes for. And you know you can't just make up a random name and backstory, because your players will somehow make that one NPC a bigger part of the story than your planned villain. What I'm trying to say is, if I had this person's cyberdeck that allowed me to quickly generate an NPC mid-game, I don't think I'd ever get stuck ever again. And the really surprising part is, this was all engineered by a 14-year-old. This D&D DM's cyberdeck uses AI to keep you on track It can also beam information to your players Over on the Raspberry Pi subreddit, Redditor Wintaru showed off what their son has made. It's a cool cyberdeck that runs off a Raspberry Pi 5, and it allows the DM to quickly access tools related to running a game of D&D. It started as a website that Wintaru created that allowed his son to share material with his players without sharing personal information, and then evolved into the LoreKeeper software that helps the son manage his campaigns. Funnily enough, Wintaru isn't 100% sure how his son achieved this. In the comments, he reveals that Claude was involved somehow, saying "he pays for [Claude] with his allowance and once I handed it over to him I've stopped looking at it." From the looks of the screenshots, it appears the device can connect to D&D Beyond, roll dice, manage campaigns, and create NPCs on the fly. Wintaru does note that the cyberdeck uses an onboard Ollama LLM for all the generation, so there's a good chance he used Claude to make the software and Ollama to create in-game assets. If you'd like to see the source code for yourself, head over to the LoreKeeper GitHub repo for all the details.
