AnimGen

AnimGen is an AI animation generator built specifically for game developers. You upload a static image of a character — say a side-view deer or a walking human — describe the action you want (walk, run, attack), and AnimGen produces a short animated preview. From there, you can trim the motion to the best loop and export it as a sprite sheet, PNG sequence, or a Unity asset with JSON metadata.

The workflow is straightforward. After uploading a character image with a transparent background, you enter a text prompt to describe the motion. AnimGen generates a 4-second video preview at 12 FPS. A built-in timeline lets you scrub through every frame, select the segment that loops cleanly, and preview how it will look in-game before exporting. You can adjust the export FPS (12, 24, or 60) to match your engine's needs. The tool also supports transparency processing during export, and it outputs metadata for easy integration into engines like Unity, Godot, Unreal, and Cocos.

AnimGen is designed for game developers who need to animate 2D characters quickly without frame-by-frame manual work. Indie developers and small teams will find it especially useful for creating walk cycles, attack animations, and idle poses from a single piece of art. The free tier gives you 120 one-time welcome credits to try it out, and there's no credit card required.
