Construct

Describe a thing. Get a hologram, a 3D model and its parts. You ask any AI agent for a thing in plain words, and it builds an animated holographic model of it in the Measured Light style, as one web page you can open anywhere, honest about what is known. The same construct exports as a 3D model with named parts and working joints, for Blender, game engines and the web.

• Any agent, any model. Claude Code, Hermes, any MCP client or any OpenAI-compatible endpoint, or by hand.
• Honest about what is known. Every fact and part says whether it is verified, supplied by you, inferred or decorative.
• One house style. Models never choose the colours, so every construct looks like it belongs with the rest.
• It repairs itself. Every problem comes back with where it is and how to fix it.
• Nothing to install. Python's standard library and a browser; no API keys or network service inside Construct.

Who it is for

What it does

In the common case:

1. You ask for something in plain words, in your agent: "make a construct of a Leica M3", or "a masterpiece of the Sydney Opera House". Before any work, the skill tells you which mode it will use, fast or masterpiece, why, and roughly how long it will take.
2. The agent looks it up. For a specific, named subject it finds real facts and reference photos. The photos are only for comparison; they are never copied into the construct or published, because they belong to someone else.
3. The agent writes a scene. A scene is a short text file that says what the thing is: the facts, each marked with how well it is known, and the parts, built from simple shapes, with how they assemble and open. The agent never draws pixels or writes graphics code.
4. Construct checks it. Something floating, a claim stronger than its evidence, a part too small to see: every problem comes back with where it is and how to fix it, and the agent repairs the scene until the check is clean.
5. Construct builds the page. One construct.html that opens in any browser, works offline and shows the construct building itself, part by part.
6. The agent reviews it. It looks at stills from every view and improves the weakest point. In masterpiece mode an independent critic takes over the judging, round by round, and you get a short report after each one.

See it in practice

The examples are real runs: each one was made by an AI agent with Construct, in fast or masterpiece mode, by Claude Opus 5.5, GPT-6.1 Sol or DeepSeek V4.1 Flash. Open any of them to watch it assemble, turn it around and read its labels.

How it works

A scene is data, never code: the agent says what the thing is, and Construct decides how it looks. That split is what keeps every const
