Features
AI 3D animation features
Rig any character, generate motion from text, retarget it, and refine it, all in one browser studio.
- AI auto-rigging
AI auto-rigging for any 3D character
Auto-rig 3D characters with AI in your browser. Nira adds a skeleton and skin weights to humanoids, creatures, and props from a GLB, FBX, GLTF, or DAE upload.
- Creature & quadruped rigging
Auto-rig quadrupeds, creatures, and non-humanoid characters
Automatically rig quadrupeds, birds, dragons, and other non-humanoid 3D characters with AI. Nira rigs creatures in the browser and exports GLB for any engine.
- Text to animation
Text to 3D animation: describe the motion, get the clip
Generate 3D character animation from text. Describe a walk, a jump, or a gesture and Nira creates the motion on your own rigged character, ready to edit and export.
- Animation retargeting
Retarget animation to any character, without bone mapping
Retarget 3D animation between characters without manual bone mapping. Nira maps skeletons automatically and applies motion to your own rigs in the browser.
- AI motion editor
An AI motion editor for refining every detail
Edit AI-generated 3D animation in the browser. Adjust keyframes, fix loops, lock contacts with IK, and build sequences in the Nira studio, then export GLB.
- Free 3D animation software
Free 3D animation software, right in your browser
Free 3D animation software that runs in your browser. Load a character, pose it, keyframe it, and export GLB. No install and no credit card. Add AI rigging and motion when you want it.
