Questions
Is afk.ai free?+
Yes. Rigging, the animation library and exports are free. You sign in with your Google account, and the site is supported by ads.
Do I have to place the skeleton myself?+
No. Tell it what the model is (humanoid, four-legged, dragon and so on) and an AI model places the joints and skin weights for you, right in your browser.
What can it rig?+
Humans and humanoids, four-legged animals, horses, birds, dragons, kaiju, spiders, snakes and fish. Each has its own skeleton and animation set.
Which file formats work?+
Upload GLB, GLTF (with its .bin and textures) or FBX. You get a GLB with the skeleton and every animation, ready for Unity, Unreal, Godot, Blender and Three.js.
Can I use the animations in commercial projects?+
Yes. The skeleton templates and animation library are CC0 (public domain), so you can use them in commercial games and videos without attribution.
What do I need to run it?+
A desktop or laptop with a graphics card, in Chrome or Edge. The first rig downloads the 1.1 GB AI model once; after that it starts right away. Phones and tablets aren't supported yet.
Does my model get uploaded anywhere?+
No. Rigging runs in your browser, and your model never leaves your computer.
