Animation

Animation

Create sprite animations from text, generate intermediate frames between keyframes, and apply AI-estimated skeleton rigs to your characters.

Text-to-Animation

Generate complete walk cycles, idle animations, attack sequences, and custom motions directly from text prompts. Describe the movement and the AI generates the frame sequence.

POST /generations/image
{
  "prompt": "cat walking animation, 4 frames, side view, pixel art"
}

Skeleton Animation

Each generated character includes an AI-estimated skeleton. Use the skeleton to apply consistent animations across different character states, transfer motion between characters, and fine-tune poses manually.

Frame Interpolation

Generate smooth transitions between keyframes by interpolating intermediate frames. This creates fluid animations from just a few posed frames.

Export Formats

Animations can be exported as sprite sheets, GIFs, and frame-by-frame JSON metadata compatible with Unity, Godot, and Aseprite.
