DungeonMessage is a free web-based messaging tool built for Dungeon Masters and Game Masters running tabletop RPG sessions. It lets GMs send private one-way messages, including text notes, clues, and images, directly to individual players or the entire table during a session, without other players seeing. It works with any tabletop RPG system, including Dungeons and Dragons, Pathfinder, Call of Cthulhu, Blades in the Dark, and any other game where a GM needs to pass private information to players.
Group chat apps like Discord require all players to create accounts and join a server before a session. DungeonMessage requires nothing from players. The GM creates a session, shares a simple link, and players can receive private messages instantly in their browser with no signup, no registration, and no app to download. It is also purpose-built for one-way GM-to-player communication, so there is no risk of players accidentally seeing messages meant for someone else.
GMs can send text notes, secret clues, lore drops, in-character whispers, images, and map fragments. Messages can go to a single player privately or be broadcast to everyone at the table at once.
