Your whole campaign
NPCs, players, locations, plot threads, encounters, and sessions in one searchable database, with typed relationships, a graph view, and both keyword and semantic search.
For tabletop RPG game masters
Your whole campaign,
on your own machine.
GM Daemon is a campaign manager and live game table. Your NPCs, lore, and plot threads live in one searchable place. When you sit down to play, it runs the tactical map for the table. Everything stays on your own computer, with no account and nothing in the cloud.

what it is
A campaign that remembers, and a table ready to run.
Most virtual tabletops are built around the battle map and the live session. GM Daemon comes at it from the other direction: it holds your whole campaign first, the NPCs, lore, plot threads, and how they all connect, then brings it to the table when you play.
A live game table
When you want a map, it runs one with fog of war, dynamic lighting, and line of sight. Put a player’s-eye view on a TV at the table, or let players join from their own devices to move tokens and roll dice.
Private by design
Everything runs on your computer. No account, no subscription, and nothing kept in the cloud. Export any campaign to a single portable file, so there is no lock-in.
AI, only if you want it
Off by default. Bring your own provider, a local model or a service you already pay for, and it only ever drafts things for you to review. You choose what the players see.
the player table
Everyone sees the game. Nobody sees your notes.
The player view shows the map filtered to exactly what the party can see, with fog, lighting, and darkvision applied, while your notes and secrets stay on your screen. Open it on a TV at the table, or let players bring it up on their own devices to move their tokens, roll dice, and run their characters.
- Players move their own tokens, wall-legal and always GM-authoritative
- Shared dice log, per-player HP and conditions, notes, chat and whispers
- Pushed handouts, pings, and the active turn
- Invite-gated remote access: one rotatable link and QR code, then each player signs in
the virtual tabletop
The tabletop is there when you want it.
GM Daemon is a campaign manager first. When you play, the tactical map is optional, and you lean on it as much or as little as your table likes: theater-of-the-mind with no map at all, a shared screen or TV in the room, players on their own devices over your Wi-Fi, or remote players through a secure, invite-gated tunnel. It's a full virtual tabletop when you need one, and out of the way when you don't.
Where it differs from a map-first VTT:
| Aspect | GM Daemon | A typical VTT |
|---|---|---|
| Built around | Your campaign and prep first, then live play | The shared battle map |
| Players | Join to run their own character: move tokens, roll dice, track HP, take notes, chat | Full token control on a shared grid |
| Who's in charge | You are. Every player action is relayed through your app and authorized there | Players act on the shared canvas, within GM-set permissions |
| Rules systems | D&D 5e, Shadowdark, Pathfinder 2e, Starfinder 2e, and Generic built in, or define your own | Varies; often one system or paid add-ons |
| AI | Optional and off by default; a private prep aid your players never see | Rare, or a paid add-on |
| Your data | Stays on your computer, with no account or subscription; export it as a portable file | Hosted in the cloud, or on a server you run |
philosophy
Built for the people at the table.
Your data stays yours
It all runs on your own computer. No account to make, no subscription, nothing kept in the cloud.
A tool for the GM, not a replacement
You make the calls and tell the story. AI helps with the busywork when you ask, and never stands in for the people at the table.
Quiet by design
It keeps your campaign organized and then stays out of your way, so your time goes to running the game.
No lock-in
Use it on its own or alongside tools you already like. Export any campaign to open, readable files and take it elsewhere anytime.
