Out now on itch.io

The full Chromatory studio

Chromatory Studio is the whole toolkit. A local-first app for your own PC that knows every paint on your shelf, matches colours with real colour science, paints your actual 3D model, and remembers every project. It is out now on itch.io, as a one-time purchase with a free demo.

Bring your own AI

Drive it from Claude or ChatGPT

Chromatory doesn't sell you another chatbot subscription. It plugs into the AI you already use. Connect Claude, ChatGPT, or a model running on your own PC, and your assistant gets Chromatory's actual tools: your real paint inventory, colour matching, your project history, and the Light Studio itself.

You, to your AI Here's a photo of a painted mini I love. Can I match this scheme with my paints?
Your AI, using Chromatory It reads the photo area by area, samples the real colours, and matches every one against the paints you actually own, with honest close-enough grades. No invented paints, no wishful substitutions.
You Paint my model like that so I can see it from the back too.
Your AI, using Chromatory It splits your STL into areas, colours each one, and renders the painted model from any angle. One consistent scheme all the way around, because it painted the 3D model, not four separate pictures.
You, next weekend Where did we leave off?
Your AI, using Chromatory Sessions are logged to the project, so the conversation picks up with the scheme, the mixes and the decisions already on the table.

Built on open standards (an MCP server and an OpenAPI tool server), so it isn't locked to one vendor: Claude Desktop and Claude Code, ChatGPT and Codex, LM Studio, Open WebUI and local models can all connect. Your AI account stays yours, and Chromatory's tools run on your machine.

What's in the studio

Built around your paints

Chromatory knows what's actually in your paint drawer, so every match, mix and scheme it suggests is something you could sit down and paint tonight.

๐Ÿ“ท

Copy a mini from a photo

Point it at a painted miniature you love. Chromatory reads each area and works out a step-by-step scheme using the paints you already own.

๐ŸŽจ

Paint the model itself

Describe a scheme or match a reference, and it paints the regions of your actual 3D model. Every angle agrees, because there is only one model.

๐ŸŽฏ

Colour match & mixing

Real colour science (CIEDE2000 and Kubelka-Munk) finds the closest paint you own, or the mix that gets you there.

๐Ÿ—„๏ธ

Paint inventory

Catalogue your collection with swatch photos, and name a paint straight from a snap of the bottle.

๐ŸŒ—

Shadow & highlight guide

Give it a scheme photo and a lighting render. For each element it hands back the shadow, midtone and highlight paints, and shows you where each one falls.

๐Ÿ““

A memory for every project

Photos, decisions, recipes and whole painting conversations land in the project log, so next month's session starts where this one ended.

๐Ÿค–

AI painting coach

Advice, a painting log and scheme mockups, all built on the paints you really have. Runs on your own AI, a local model, or turns off completely.

๐Ÿ”’

Local-first and private

Everything runs on your own PC. Your data, photos and models stay with you. Pair your phone or browser to it whenever you want the bench in your hand.

The legacy browser versions of the Light Studio and Assembly Workbench stay free; the studio versions are where new features land.

Get it

Out now, still indie

Chromatory Studio is available today on itch.io: a one-time purchase, not a subscription, with a free demo you can try first. The demo is the full app with one project, and the paint shelf you build in it carries over if you buy. The browser tools stay free either way, updates keep coming, and the Discord is where news lands first.
