Start with a character.
Build a character profile and generate multiple poses from a pose library - with a style library you can expand yourself. Each character keeps its own set of saved poses to work from.
Build sprites, staged scenes, pose-driven motion, and game-ready exports in one tool.
MotionWeaver™ is a real desktop workflow for animation cleanup, scene staging, AI-assisted motion, character generation, and production exports. It's built for creators who need more than a prompt box and more than a timeline alone — and it's the engine behind every animated sprite on this site.
The workflow
AI video to game-ready sprites, end to end.
MotionWeaver is one connected desktop pipeline: pose a character, animate it, turn the result into clean game-ready frames, then sequence and compose - all in a single project.
Bring the poses to life.
Generate a transition video between two poses, or animate a single pose - swapping in whichever Replicate model suits the job.
Video into clean frames.
Convert the video to frames, remove backgrounds fast with advanced tools, and edit frames - then export sprite sheets for Unity, Godot, Adventure Game Studio or a custom engine, fully configurable.
Stitch it together.
Place a character's animations, or whole scenes, back to back - and use advanced tone-matching tools to eliminate variation between clips.
Make the full video.
Bring every animation, sound and piece of music into one scene and export a finished MP4.
Engine-ready output.
Frame-accurate sprite sheets for Unity, Godot, Adventure Game Studio or a fully customisable custom format - plus MP4 video straight out of Stage.
Real desktop software
Built like a tool, not a toy.
Desktop-first, Windows-first
A packaged desktop application with real projects, save, recovery and exports - not a browser tab that forgets your work.
The .mwproj project model
A canonical project format where the engine owns state, history, assets and cross-mode persistence.
More than a prompt box
AI generates the motion - the rest is the hands-on craft a prompt alone can't do: fast background removal, frame editing, tone-matching across clips, sequencing and scene composition.
The VARLIS games pipeline
MotionWeaver produces the sprites; Alepou Canvas assembles the games. Every animated character on the games page came through it.
Bring your own API key.
MotionWeaver is desktop software you own. The AI features connect to your own provider account and API key - so AI usage is separate, and billed by your chosen provider, not bundled into the purchase. Purchase does not include AI credits. (Replicate is the current easy-start recommendation.)
An AI video-to-sprite pipeline, on your desktop.
MotionWeaver is in active development and already produces the sprite art across VARLIS's games. Get in touch to follow along or talk about using it.
