SpriteGen

SpriteGen is a web-based AI sprite creator for game developers, built by Luki. You describe a character and an action, pick a camera view and style, and get an animated sprite sheet as a transparent PNG. The site also offers a free browser pixel editor and related sprite tools.

What It Is

SpriteGen generates pixel-art and illustrated sprite sheets from plain-language prompts, without needing animation skills or a rig. According to the About page, an LLM reads the character and action and plans each frame, then an image model draws the whole animation on one transparent sheet. Users get a live looping preview before downloading.

Workflow and Outputs

You choose a view (side, top-down or isometric), a style from twelve built-ins, an action such as idle, walk, run, jump, attack, cast, hurt or death (or type your own), and 6, 8 or 12 frames. Top-down and isometric views support 8 directions, with each direction produced as its own sheet. A character reference image can help keep a character consistent across actions, and the Next action button continues with the same character. Exports include a transparent PNG with evenly spaced cells, a GIF, separate frames in a ZIP, or an atlas with Aseprite and TexturePacker JSON. The FAQ says sheets slice in Unity, Godot, GameMaker and Phaser, and notes that AI output may need manual adjustments.

Companion Tools

Besides the main generator, the site offers a GIF to Sprite Sheet converter, an AI Sprite Maker for single transparent sprites such as items or icons, a Sprite Sheet Maker for packing existing frames, and a Pixel Art Maker that runs in the browser without sign-in for drawing frame by frame and exporting PNG, sprite sheet or GIF.

Usage and Licensing Notes

New visitors can try generation without an account, and sign-up grants starter credits. The FAQ states that generated sprites may be used personally and commercially, though outputs are not exclusive. Generations funded only with free credits may be selected for the public gallery, while paid-credit generations are not eligible.
