One file and done
Drag it into Unity, Godot, Blender or your website and that is it, materials included. Nothing to reassign.
A desktop 3D editor where you ask the AI for a part and watch it appear in the window. You correct, the AI carries on. And what comes out goes straight into Unity, Godot or Blender.
For Windows, and built to be driven by your own AI (Claude or another capable model). Free 8-day trial, then a one-time payment. The models can be downloaded free today.

You ask. And you watch it appear.
Model it yourself with the mouse, or ask for it and watch. Both hands work on the same file.
You ask for it
In your own words, as you would ask a person. No commands to learn, no code to write.
It builds it
It assembles real geometry, part by part. Not an image: a model you can open, edit and export.
It checks its own work
It looks at the result, spots what is wrong and goes back in to fix it. Just as a person would.
You see it live
The window updates on every change. Watch the part come together and step in whenever you want.
A real sessionLive
You: An off-roader with a hard top,a snorkel and the spare wheel at the back.
Studio: Done — 34 parts. It is in your window.
Studio: Checking the render… the hood cuts throughthe windshield. Fixing it.
Studio: Fixed.
You: Lower the roof a little.
Studio: Done. Exported to offroader.glb
It goes where you work.
A tool that does not export well is a toy. Four outputs, all ready to import without touch-ups.
For everything else
The format every 3D program opens, however old. Comes with its materials and textures.
If your game is 2D
The part rendered from every angle on a transparent background, ready to use as a sprite.
All together
A folder with all of the above plus the thumbnail and the spec sheet. What you hand your team without explaining anything.

Early access
The whole editor, one payment.
No subscription and no credits. You buy it once, install it, and the AI models inside your own computer.
Early access: it has bugs, and they are fixed through updates — every 1.x update is included. The price reflects that.
10USDone-time paymentUp to 3 computers
The desktop editor
Modeling, 132 materials and a high-quality GPU renderer: glass that refracts, water with waves, metals that reflect.
The AI connection (MCP), ready to go
Claude, Cursor or any MCP client, connected by the installer. Nothing else to install: no Python, no Node.
Export to any engine
GLB, OBJ, sprite sheets and asset packs for Unity, Godot, Roblox and Blender.
What you make is yours
Use and sell your models commercially, with no royalties or extra fees.
Works offline
Activate once with internet; after that it runs without a connection. Every 1.x update included.
Bring a capable AI
Halcyon Studio is built to be driven by an AI, and none is included. Connect your own MCP client (Claude Desktop, Claude Code, Cursor…) running a top-tier model such as Claude Sonnet or Opus. Small or local models struggle, and without an AI it is a simple manual editor: asking for a model and watching it get built is the heart of the product.

Sponsor a piece
Put your name on the next piece.
You leave us an idea. We model it our way, post the process on Instagram with your name, and the piece joins the catalog — free, for anyone.
It is not a custom commission, and that is the point: you provide the spark, we provide the interpretation. You never quite know what will come out.

You propose
An idea in a few words — an object, a scene, a whim. Up to 280 characters, which is a spark, not a spec.
We interpret it
We model it as we see fit. The judgment is ours: no revision rounds, no "that is not how I pictured it", because what you are sponsoring is the piece, not directing it.
It goes public
A process video on Instagram, with your name or alias. And the piece joins the catalog for anyone to download, free, like all the others.

Nothing adult, no third-party brands, nothing illegal — if your idea falls in there we refund you and no harm done. All the details in the terms.
