afk.ai: browser-based AI rigging and animation for 3D models

What afk.ai automates

afk.ai is a browser-based service for rigging and animating 3D models. A user uploads a character, creature or object, selects its type and lets the service place joints and skin weights.

The site describes fifteen skeleton templates and more than 170 animation clips, covering humanoids and a range of animals and fantasy creatures. These are supported template families, rather than a demonstrated guarantee that every possible mesh will deform cleanly without adjustment.

From an existing model to an export

Users can preview animations on their own model before downloading the rigged result. The site lists GLB and FBX exports for workflows including Unity, Unreal Engine, Godot, Blender and Three.js. It also describes additional import formats, with some conversion performed in the browser.

The rigging itself runs on the service’s cloud GPU. “Runs in your browser” therefore describes the interface and installation experience, not an entirely local processing pipeline. The service says uploaded models are used for checking and rigging and are not retained afterward; its privacy terms remain relevant for confidential or unreleased assets.

What to check before using the result

The published desktop requirements name Chrome or Edge and say phones and tablets are not supported in that workflow. The site describes rigging and animation preview as free to try; confirm the account’s current export terms before planning a production pipeline around it.

A good evaluation asset includes the difficult parts of the intended character, such as bent limbs, unusual proportions or attached props. Inspect joint placement, deformation and the exported clip inside the target engine. Previewing a plausible animation in the browser is useful, but the final test is whether the rig behaves correctly in the scene where it will be used.
