LAPLACE Persona

Control LAPLACE Persona from your Stream Deck. LAPLACE Persona is a desktop app that puts a Live2D or VRM avatar on your screen, and this plugin lets VTubers and streamers drive it hands-free: switch models and scenes, trigger hotkeys, expressions, and motions, and move, scale, or reset the avatar mid-stream without leaving your game or chat.

Included actions:

Switch Model: swap the avatar on stage to any model in your library

Activate Scene: apply one of your saved scenes

Trigger Hotkey: run any of the active model's hotkeys

Run Shortcut: fire the app's global shortcuts, even ones with no key binding

Toggle Expression: turn an expression on or off

Play Motion: play any of the active model's motions

Move Model and Scale Model: nudge or resize the avatar; hold the key to keep going

Reset Transform: snap position, scale, and rotation back to default

How it works: the plugin connects to the running LAPLACE Persona app through its local WebSocket plugin API. Enter the connection settings once in any action and every action shares them; dropdowns for models, scenes, hotkeys, expressions, and motions fill in live from the app.

Requirements and setup: LAPLACE Persona laplace.live/persona running on the same computer or reachable over your LAN. In Persona's settings, enable the plugin API and create an API key, then paste it into any action's settings. The address defaults to 127.0.0.1:25034.
