Lemegeton

Lemegeton is a digital grimoire for Blood on the Clocktower storytellers — track claims, log ability uses, and record nominations without breaking the flow of the game. Flexible seat layouts, a live grimoire board, and phase-by-phase chronicle notes keep the whole game state visible at a glance, and a contradiction review screen surfaces conflicts between claims, logged actions, and final reveals to help you figure out what really happened.

It works entirely offline with zero data collection — your notes and game sessions never leave your device. Completed games are saved locally so you can review or replay them later, and the app includes Korean localization for storytellers who run games in Korean.
