Stop hand-drawing walk cycles with AutoSprite

Tired of animations that never look quite right? Want your 2D characters moving today, not next week? AutoSprite turns one drawing into a full animated moveset, about a minute per move, and the character stays on-model in every frame.

One drawing in. It starts running. Their knight, 25 frames, generated from the single image on the left.

One image in. A full moveset out.

Upload a character. Pick idle, walk, run, jump and attack, or type your own: "cast fireball", "pick up item", "death". Need something stranger? Film the movement and AutoSprite paints your character onto it. Every frame comes from your image, so the helmet, the cape and the proportions stay exactly where you drew them. No more slideshow of cousins.

And it's fast

Thirty to sixty seconds per animation. A hero with five moves is done before your coffee cools. That is the difference between a jam entry with one animated character and a jam entry with a cast.

Play it before you ship it

The built-in preview drops your character into a little level. Run around with WASD, nudge the speed, and if one move looks off, regenerate that one move. Not the set.

Drop it into your engine

Every export is a spritesheet plus a JSON file with the frame data. Unity, Godot, GameMaker and Phaser all take it as-is, and there is a Unity extension that imports in one click.

Got a whole cast?

Advanced Mode runs every character in your library through one moveset. A hero, three enemies and a boss with five moves each is 25 animations, and it is one job.
