Sketch MetaDemoLab is an innovative browser‑based AI animation tool developed by Meta’s Fundamental AI Research team that brings your drawings to life. Users upload a hand‑drawn sketch (typically a character with legs and arms), and the AI analyzes the structure, detects joints, and applies predefined animations like walking, dancing, jumping, or waving — all without requiring animation skills or software. The output can be downloaded as animated GIFs or video files, making this a fun, creative way to turn doodles into dynamic media for storytelling, social content, education, or quick prototype animations. The entire experience runs in the browser, and no signup is needed, with the basic functionality available for free.
