Sprite Flow

AI sprite sheets and character animations for indie game developers

Style-consistent animation sets

Lock an art style once and generate idle, walk, run, jump, and attack animations where every frame keeps the same palette, proportions, and detail level.

Multi-directional sprites

Automatic 4-directional and 8-directional generation for top-down, side-scroller, and isometric games, suitable for RPG and strategy projects.

Engine-ready exports

Download PNG sprite sheets, APNG/GIF previews, or ZIP frame folders with JSON animation metadata and controller presets for Unity, Godot, and Unreal.

Full 2D asset suite

Character design, batch NPC generation, tilesets, game maps, props, scene asset extraction, sprite replacement, and an AI pixel art fixer in one workspace.

Strengths & Pros

+Purpose-built for game pipelines, with sprite sheets, JSON atlases, and engine presets rather than generic image output
+Style locking addresses the biggest pain point in AI sprite work: frame-to-frame visual drift
+Covers characters, tilesets, props, maps, and audio so a prototype can use one tool
