Animation Paper vs VTube Studio

Animation Paper has no write-up on Specifiction yet; its figures are above.

VTube Studio is an app for Virtual YouTubers to animate Live2D models. It runs on Android, iOS, macOS, and Windows, with face tracking through a webcam or iPhone, including eye tracking and winking. Webcam-based hand and gesture tracking can activate expressions and animations. Scene controls include hotkeys, microphone lip sync, animated PNG props, and visual post-processing effects. Users can attach images, animations, and customizable Live2D props to a model, with tracking and hotkeys available for control. Twitch integration lets viewers trigger hotkeys through emotes, redeems, subscriptions, and chat commands. Developers can use the VTube Studio API to make plugins that control models or trigger animations and expressions. VNet lets Steam friends collaborate on Windows and macOS, with up to six people per session; it requires launching through Steam and the separate $19.99 VNet DLC. The free Steam app shows a webcam-tracking watermark; removing it costs $14.99 once. iOS requires Face ID or an Apple A12 or newer chip, and Android requires Google ARCore support.
