The player-facing TV: a live combat board with party HP, hope and fear pips over the encounter art

LIVE— DUNGEON

Lights · Music · Sound

One tap changes everything.

Lights

Philips Hue and Tuya, controlled over your LAN — no cloud at game time. Animated effects when the scene calls for them, smoothest on Hue.

Music

Spotify Connect or your own files, a playlist per scene. The tavern always knows its own songs.

Sound

Overlapping one-shots and loops, with Freesound search built in. Thunder on top of whatever’s playing.

10 seconds

See a event in action.

Scenes & events

Save the tavern once. Return any time.

A scene is the whole room — lights, playlist, soundscape, TV — saved as one tile. Events fire stingers on top of whatever’s playing: a lightning flash and a thunderclap, one key.

Combat Dungeon Mystery Tavern

The Scenes tab — colored one-tap scene tiles: Combat, Dungeon, Session end, Mystery, Rest, Tavern

The event timeline editor — a Thunderstorm event with rain, wind and thunderclap sound clips shown as waveforms, and lightning flash light clips on parallel tracks

Events & timelines

Script the whole storm.

An event can be a single stinger — flash, thunderclap, done — or a whole sequence on a video-editor timeline: sound and light clips placed to the millisecond, fired over the live scene from one tap or one Stream Deck key.

The players’ screen

Push the story to the big screen.

Maps, handouts and live boards — party HP, fear, the enemies they’re facing — on a TV the whole table sees. The screen runs key-free; GM controls stay private on your tablet.

Ambient Director's player-facing board running on the table's wall-mounted TV: five party members with HP, Stress, Armor and Hope pip tracks down the left, a Fear skull track across the top, and four Goblins down the right, over desert encounter art

The board editor — a live 16:9 preview with draggable elements, background colors and image upload

The Encounters tab — a prepped fight, ready to run to the TV

The game layer

The table’s numbers, handled.

A party tracker, a bestiary, prepped encounters. Daggerheart and D&D 5e presets built in — take a hit point from the panel or a Stream Deck key.

Assistant & MCP

Ask for a mood, get the room.

A built-in assistant — bring your own key from Anthropic, OpenAI or Google — that can run the whole room: scenes, events, sounds, boards, the party tracker. The same tools speak MCP, so Claude Code or Claude Desktop can drive it too, or prep next session’s boards with you. Setup and secrets stay off-limits.

Honest noteIt’s an unsigned open-source build, so SmartScreen will ask — “More info → Run anyway”.
