VMSC is a free desktop app that bridges your live streaming platforms to interactive outputs in real time. When a viewer sends a gift, follows, subscribes, or chats — VMSC triggers actions on your VRChat avatar, PiShock devices, VTuber model, OBS overlays, TTS, sound alerts, smart lights, game servers, and more. Connect TikTok, YouTube, Twitch, Kick, Streamlabs, and StreamElements all at once. Voice commands via Whisper.cpp, a mobile stream deck, live chat popout, and a standalone alert engine — all built in.
