For Foundry VTT game masters · Now in beta

Your table's AI narrator.
Live, inside Foundry.

GM Grimoire watches your session and narrates the moment it happens — the combat blow, the scene reveal, the lore your players just uncovered. No prompts. No alt-tabbing. It reacts to the game you're already running.

Built for the game you run

Every page speaks your genre — pick a system to see its skin.
