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.
