Grimoire
A downloadable tool
AI image tools for pixel artists and indie retro-style game development built to accelerate creative workflows.
Generate, control, refine, convert and export game-ready art from one focused canvas.
Grimoire connects local ComfyUI workflows directly to Aseprite, letting you generate, refine and experiment without leaving the canvas. Use your own models, run everything locally, and skip the extra generation API costs.
With support for third-party APIs, giving you more flexibility and control over your tools.
Stop switching between tools.
Most AI workflows look like this:
- Generate in one tool
- Upscale in another
- Clean in external editors
- Convert for pixel art elsewhere
- Repeat
Grimoire fixes this.
Everything inside Aseprite:
- AI generation local or cloud
- Structure control with ControlNets or IPAdapters (*for sdxl)
- Pixel-art tools (custom scale specific neural pixelization model, pallete reduction, wang tileset generation, background removal)
Custom Loras
Gain access to our growing selection of custom trained loras to speed up the process of asset generation and iteration for game development.
Walk
Generates character sprites across walk cycle frames, maintaining consistent proportions and silhouette throughout.
Portrait
Generates character busts and headshots with clean structure.
Wang
Generates collections of terrain and environment tiles designed to fit together consistently across edges, corners, and transitions.
Border
Generate tileable interior wall borders with consistent structure.
Wall
Generates tileable wall surfaces with repeatable texture and color across sections.
Cliff
Generates cliff faces and ledge tiles with clear direction and edge definition.
Single Tile
Generates individual terrain tiles designed to repeat seamlessly in any direction.
Building
Generates exterior building structures with matching scale and architectural detail.
Small Items
Generates small icon-sized sprites and pickups with a shared highlight and shadow language across outputs.
Medium Items
Generates mid-sized sprite objects with matching perspective and shading across a set.
Large Items
Generates large props and set pieces that hold together in scale and detail across multiple tile spans.
Core Tools
Text to Image
Generate assets from prompts using local models or hosted APIs.
Image to Image
Transform existing artwork while preserving structure and composition.
Inpaint & Outpaint
Edit selected regions or extend canvases with contextual consistency.
IPAdapter
Guide generation using reference images, styles, or masked regions.
ControlNet
Lock structure, pose, depth, and line work for precise output control.
API
Use hosted providers when you want generation without local checkpoints.
Tools
A collection of tools for pixel art workflows ranging from our custom neural pixelization model, pallete reduction, wang tileset generation, background removal and controlnet reference generation.
