Over the past few weeks I've been building something I thought should already exist.

It's a prototype that converts plain English into a 3D rigid-body physics simulation.

For example, I can write something like:

"Create a sphere of radius 0.2 m and mass 1 kg, place it 5 m above the ground, throw it with velocity 2i + 3j under Earth's gravity."

The system generates the simulation and immediately plays it.

At the moment it's quite limited:

\- It only supports spheres and cuboids.

\- Simulations are around 10 seconds long.

\- You can't edit the generated simulation afterwards.

\- It's definitely still a prototype.

The physics engine itself is something I tried creating from scratch. The AI's job is simply translating natural language into the simulation setup.

I'm attaching a short demo video below.

I'm not trying to promote anything—I honestly don't know if this solves a real problem.

Would you use something like this?

If yes:

\- What would you use it for?

\- What features would make it genuinely useful?

\- Who do you think would benefit most from it?

I'd really appreciate honest feedback, even if the answer is "I wouldn't use it."

I built a prototype that turns plain English into a 3D physics simulation. Would anyone actually use this?
