Suppression du « npm install -g npm@latest » du Dockerfile web : cible mouvante inutile — le npm embarqué dans node:20 suffit pour npm ci (lockfileVersion 3) et le build Angular.
DM Loremind
English · Français
A self-hostable web app for game masters who want to centralize their world, campaigns and characters — with a context-aware AI assistant.

What it does
DM Loremind brings together what a game master usually scatters across several tools. The app is built around three core modules, augmented by an AI assistant that draws on all of your content.
Lore
Build your world with a tree of templated pages: locations, factions, NPCs, events, organizations... Each page type follows a configurable template, which keeps things consistent and makes navigating rich worlds easy.
Game System
Store the rules of your game system (D&D, Nimble, homebrew...) and define the matching character sheet templates. Indexed rules can be injected into the AI's context for answers that stay true to your system.
Campaign
Structure your campaigns as Arcs → Chapters → Scenes, with a clear split between GM-only and player-facing content. Manage PCs and NPCs through dynamic sheets based on your chosen game system's templates.
AI Assistant
A context-aware assistant that pulls from your Lore, rules and campaigns to answer your questions, suggest consistent content, or improvise around an unexpected situation at the table.
The AI runs locally via Ollama — your data stays on your machine — or in the cloud with your own API key via 1min.ai, Mistral, Google AI Studio (Gemini) or OpenRouter.
Quick start
Desktop (easiest) — grab the latest installer from the Releases page: Windows .msi or Linux .AppImage, then run it. Your data stays local.
Self-host with Docker — on Linux:
curl -fsSL https://raw.githubusercontent.com/IGMLcreation/LoreMind/main/installers/install.sh | bash
On Windows, follow the installation guide.
Documentation
The full documentation (installation, configuration, getting started) lives at loremind-docs.igmlcreation.fr/en.
Live demo
A demo instance is available at loremind-demo.igmlcreation.fr.
A few limitations to be aware of:
- 10 concurrent users maximum (isolated instances)
- Sessions limited to 20 minutes before reset
- The AI features are not included in the demo (they require an AI provider — local Ollama or a cloud API key — configured server-side)
Support the project
DM Loremind is and will remain free when self-hosted. Development moves faster with your support:
- Patreon — early access to features, roadmap voting, exclusive devlogs
- Discord — announcements, support, user feedback
License
DM Loremind is distributed under the GNU AGPL v3 license.
In practice:
- You can use it for free, host it, modify it, and redistribute it.
- If you modify the code and expose the modified app over a network (even as a private SaaS), you must make your changes public under the same license.
- The worlds (Lore) and campaigns you create with DM Loremind belong entirely to you — the license only covers the application's code.
