Built in under 12 minutes, a Grok Build demo turns cancer immunotherapy into an interactive web app

A user says they created a CAR-T Development Lab with Grok Build in just two prompts and under 12 minutes, then continued editing it from the Grok iPhone app. The result is a web-ready educational simulator for receptor design and T-cell therapy experiments.

The site lets users design CAR constructs, test them against model tumors, and compare T-cell phenotypes.
It includes presets for CD19, BCMA, GD2, and HER2, plus risk indicators like off-tumor risk.
The demo shows live simulation elements such as antigen match, surface CAR density, transmembrane behavior, and chassis ranking.
The post is essentially a fast-build showcase for Grok’s website/app workflow rather than a cancer research claim.
