Charios

Charios is an AI-powered browser-based 2D character animation tool that rigs your PNG art in seconds and applies mocap-driven animations you can export as PNG sequences, JSON or Unity prefabs. The AI retargeter automatically maps and normalizes bone lengths, extrapolates missing hand/foot bones and adapts bundled or uploaded humanoid mocap (BVH/FBX) to your character so non‑animators can get believable motion fast without installing software or hand‑keying frames. Free forever for three projects to test the workflow, with Pro and Studio plans for larger projects, priority processing and team features when you’re ready to ship.
