LAPLACE Chat

The LAPLACE Chat dashboard integrates with VTube Studio (VTS from here on), so you can drive the basics of VTS right from the dashboard: switch models, switch expressions, and trigger hotkeys

This feature shipped on Apr 2, 2025

Usage

• In VTS, double-click to activate the UI, then click the gear icon to open settings
• In the settings window on the right, find the "VTube Studio Plugins" panel
• Turn on the API and note the port number (usually 8001)
• Open the LAPLACE Chat dashboard, enter the matching connection details in the sidebar settings, and click "Connect"
• Go back to VTS and choose "Allow" in the authorization prompt that appears
• Return to the LAPLACE Chat dashboard and click "Connect" again to finish authorizing

Hotkey Mapping

Once the LAPLACE Chat integration with VTS is on, your VTS hotkeys map to the LAPLACE Chat dashboard automatically, and without modifier keys. Expression 1, for example, fires by pressing the 1 key in the dashboard. A combination such as Shift - 2 also fires by pressing 2 in the dashboard

So with the VTS integration on, you can turn off the global hotkey trigger option in VTS (the globe icon) and let the LAPLACE Chat dashboard take over hotkeys

Security

• The VTS integration in LAPLACE Chat runs entirely in your local browser; this site never uploads any VTS-related data
• Because of HTTPS security rules, the LAPLACE Chat dashboard can only integrate with a VTS instance on the same machine, meaning your VTS must be reachable over localhost or 127.0.0.1
• If the VTS instance and LAPLACE Chat are on different machines and you still want the integration, you first have to wrap the VTS API as wss:// through a third-party tunneling service such as ngrok
