About Grimoire Companion

Grimoire Companion is a digital grimoire — a tabletop helper built for players of Blood on the Clocktower. Instead of juggling paper notes and a physical character sheet, it lets you track the grimoire yourself: pick your player count, seat everyone by name, and deal out characters with a tap.

Each seat tracks a player's character, whether they are alive or dead, and whether their ghost vote has been spent. You can keep private notes on every player, and when a token's character is unknown you can mark down which characters you think it might be. Tapping a character token opens a full reference screen with the character's ability, reminders, tactics for the first and second nights, and a defence guide for when you are nominated to die.

The app is designed for real tables of five to fifteen players, in person or online, and it works on phones, tablets and desktops. Everything is saved between sessions, so you can pause a game overnight and pick it up exactly where you left it — or restart with the same players for a fresh script in seconds.

Grimoire Companion is an independent, unofficial tool, built and maintained by a Blood on the Clocktower enthusiast using the Base44 platform. It is not affiliated with or endorsed by The Pandemonium Institute; the official game and its characters remain their creation.
