Overview
A portable, offline-first DM tool built with Flutter. Manage combat, track timelines, and project a rich campaign wiki seamlessly on any device.
Overview & Key Features
Project to Players
Click "Toggle Player Screen" to open a second window. Drag any image — NPC portrait, item card, or map — to the "Drop to Project" bar. It appears instantly on the player-facing screen.
Battle Map Toolkit
Load a map and use four tool groups: Navigate to pan, Ruler/Circle for measurements in feet, Draw for annotations, and Fog to reveal or hide areas. Everything syncs to the player screen in real-time.
Mind Map Canvas
Right-click to add Notes, Images, or Workspaces. Middle-click to pan. Zoom freely — the LOD system keeps everything smooth no matter how complex your world gets.
Soundpad
Open the audio panel, pick a theme (e.g., "Forest", "Tavern"), and use the Intensity Slider to dynamically shift the music. Build custom themes with layered tracks.
