What Is an AI 2D Puppet Animation Tool?
An AI 2D puppet animation tool is software that uses artificial intelligence to simplify and accelerate the animation process for 2D characters built with a digital skeleton or 'puppet rig.' The 'AI' typically refers to features like automated lip-sync from audio files, real-time facial and body motion capture using a standard webcam, and assistance with the complex rigging process. These tools are invaluable for content creators, VTubers, and independent animators, allowing them to produce dynamic, expressive character animations more efficiently without needing to manually keyframe every movement.
