WorldKinetics.app — Demo video

WorldKinetics. Prompt to product. Customize everyday physical products without learning CAD. Repair a broken part, make something fit your space, or make it your own. Our working prototype demonstrates a cabinet handle: start with known mounting dimensions, generate a handle, then ask Astra to broaden the grip and add a thumb rest without changing what must stay fixed. Users see the actual generated 3D geometry, review numerical checks, and explicitly approve the result. The difference from simply asking an AI to generate CAD is continuity and verification. WorldKinetics preserves requirements across revisions, independently measures the resulting geometry, shows what changed, and ties the downloadable files to the exact approved version. A convincing picture or the model saying “done” is not enough. Astra writes executable build123d Python. An isolated CAD process constructs the solid, and separate checks evaluate mounting geometry, clearance, preservation and the requested modification. The interface renders actual exported geometry, not an AI-generated illustration. The workflow ends with a prototype handoff package: STEP, STL, editable source, requirements, check results and guidance for self-printing or requesting a supplier quote. It helps users take the next step toward a physical part instead of leaving them with an unexplained download. Visit https://worldkinetics.app/ and click through to the 60-second working demo at https://worldkinetics.app/demo/. The recording demonstrates the local application; public live generation is not connected yet. Digital checks do not establish physical fit, strength or manufacturing readiness.
