I Built an App in Minutes. Here's Exactly How I Did It.

Most people think building software requires years of training, a developer, or a big budget. It doesn't. Not anymore.

Here's something I did recently that stopped me in my tracks — not because it was hard, but because of how easy it was.

I built a fully functional, interactive 3D Rubik's Cube that runs in any web browser. No installation. No code written by hand. No developer. Just me, a clear idea, and a two-step process I want to show you.

The rule I follow: measure twice, cut once.

In carpentry, you don't just start cutting. You measure, plan, then act. The same principle applies here. Before you ask AI to build something, ask it to plan the build first. That plan becomes your instructions. Then you build from the instructions.

It sounds obvious. Most people skip it entirely.

Step 1: Write what you want in plain language

I typed out what I had in mind — a 3D Rubik's Cube sitting in a moody, dimly lit environment with a spotlight on it. Realistic colours. Smooth animations when you twist a layer. A floating frosted-glass control panel at the top with buttons for every standard Rubik's move, scramble, undo, reset, a speed slider, and keyboard shortcuts. Sleek, dark, minimal design.

No technical language. No code. Just a description of what I wanted to experience.

Then I asked Claude — the AI I use — to turn that description into a detailed technical build prompt. A proper spec. Something a developer (or another AI) could follow without having to guess or make a single decision.

Step 2: AI writes the prompt — a detailed tech spec

What came back wasn't an app. It was a blueprint. A structured document specifying the exact tech stack, every file needed, the full HTML structure, all the styling in detail — exact colours, spacing, the frosted glass blur effect — and step-by-step logic explaining how the cube is built, how moves work, how dragging is detected. Every interaction described. Every common mistake flagged.

I didn't write a line of that. I just described what I wanted.

Step 3: Use the spec to build the app

I took that blueprint, pasted it into a fresh Claude Artifacts window, and watched it build. The result — a working, interactive 3D Rubik's Cube running right in the browser — is in the video above.

Start to finish: minutes.

Why this matters for you

If you work in pharma, healthcare, or any field where information needs to be communicated clearly and engagingly — this approach changes what's possible. Patient education tools, interactive explainers, data visualisations, calculators, demos. Things that used to require a development team and a budget can now be prototyped in an afternoon.

You don't need to know how to code. You need to know how to describe what you want — and how to ask AI to do the thinking before it does the building.

Measure twice. Build once.
