AI motion editor
An AI motion editor for refining every detail
Generated motion is a starting point. Nira's studio gives you a timeline, a sequencer, live IK, and motion locks to turn a clip into the performance you want, and you can ask Nira to make the change for you.
Ask or adjust
Tell Nira "hold the reach a little longer", or drag the keyframe yourself.
Live IK
Move a hand or foot and the limb follows, with contacts you can lock in place.
Loop fixes
Close the gap between the first and last frame so idles and cycles loop cleanly.
A timeline for AI-generated motion
Every clip in Nira, whether generated, from the library, or retargeted, lands on a keyframe timeline. You can scrub, set keys, change timing, and trim, the same way you would in a desktop animation package, without installing one.
Build sequences
The sequencer arranges clips end to end so you can build a longer performance from short generations: walk in, stop, look around, wave. Blends between clips keep the transitions smooth.
Pose with IK and motion locks
Live IK lets you place hands and feet directly. Motion locks pin a body part to a position across a range of frames, which is how you stop a planted foot from sliding or keep a hand on a railing.
Match a pose from a photo
Drop in a reference image and Nira poses your character to match it, plants the feet, and keys the pose on the timeline, which makes it quick to block key poses from reference.
Frequently asked questions
Can I edit a clip after Nira generates it?
Yes. Every clip is keyframed on the timeline, and you can adjust it by hand or ask Nira to change it.
Are the editing tools on the free plan?
Yes. The free plan includes rigging, pose mode, keyframes, the sequencer, and export. Saved chats and animation packs come with paid plans.
Do I need to install anything?
No. Nira runs in a modern browser with WebGL 2, such as Chrome, Edge, Firefox, or Safari.
