Our take on MITHOS: Game Master's TTRPG Toolkit

Rather than organizing a session through menus, tabs, or a ruleset-specific structure, MITHOS uses a free-panning tabletop-style canvas. Its system-agnostic approach also replaces the genre convention of tying preparation tools to one rules framework.

What is MITHOS: Game Master's TTRPG Toolkit?

MITHOS is an offline, system-neutral toolkit for running tabletop roleplaying sessions from a locally saved dashboard.

Its movable workspace brings maps, NPC images, trackers, and notes into one session view. It includes party and combat tracking, NPC creation and storage, a bestiary, shop and weather tools, a calendar creator, time tracking, map viewing, session recording, quick notes, dice rolling, and configurable layouts. Multiple campaigns can be managed, with a map or combat tracker shown to players on another screen. A character-sheet builder supports different game systems. Notes can be opened and changed through Obsidian, OneNote, Google, and Notion integrations. The toolkit functions without internet access and requires a one-time purchase rather than a subscription.
