AS Adventurer is a free, open-source tool for streamers who want an animated, face-reactive character on their stream without the cost or complexity of a full Live2D rig. It sits between two common approaches: static PNG avatars that simply bounce when you talk, and full Live2D models driven by VTube Studio. Instead of replacing either, it offers a middle ground where your character swaps between different animations based on what your face and voice are doing in real time. The tool reads facial expressions from an iPhone running VTube Studio or iFacialMocap, or from a webcam using MediaPipe. When you smile, frown, look surprised, or close your eyes, the overlay swaps to a matching animation. It also detects when you are speaking through microphone volume and when you are typing through keyboard activity. Each expression state has its own idle and speaking variant, so your character looks appropriate whether it is resting or talking. You supply the art in formats like WebM, GIF, PNG, or MP4, and the tool handles the transitions between states. Beyond automatic expressions, AS Adventurer supports a manual emote system. From a control panel in your browser, you can trigger one-shot animations, held poses with intro and outro sequences, and nested sub-animations that chain together, such as drawing a sword, igniting it, and then slashing. Emotes can include sound effects and multiple random variants. You can also switch between multiple character models on the fly, making it suitable for Discord collaboration reactive setups where different people drop their sprites into a shared folder. Setting it up involves starting a local server, either by running it from source with Node.js or by downloading a pre-built standalone executable that requires no additional software. You add your character animations to an assets folder following a specific naming convention, connect your face tracking source, and then add a transparent browser source in OBS pointing to the overlay. Everything runs locally on your machine, with no data leaving your computer, and the server is designed to be lightweight enough to run on slower hardware.
