What is DM Loremind?

A complete workshop to run your games

Lore, your knowledge base

Pages, folders and templates to build your world. All linked in a navigable graph.

Campaigns & sessions

Arcs, chapters, scenes and tracked sessions, with an AI memory unique to each table.

Sheets & NPCs

Characters, enemies, items, random tables — each system with its own rules.

The knowledge graph

Your characters and lore interconnect based on the pages you've linked together.

Import rules or a campaign from PDF

With AI, digest a rulebook in minutes to build your game system. You can also import a campaign to create it in a fraction of the time.
