Reddit built an in-house AI prototyping tool called Reddit Proto, according to Blair Metcalf’s article in Lenny’s Newsletter. It maps Reddit’s design system to production code so designers and product managers can make interactive prototypes.

The tool reportedly uses real Reddit user data and deploys prototypes internally through Kubernetes. That makes it a practical example of AI being put into a product team’s workflow, rather than another demo that ends at the prompt box. The account comes from Metcalf’s article; the reported details are not independently established here. The use of real user data is also a point worth scrutinising, not a detail to wave past on the way to a tidier prototype.

Discuss: Should product teams be able to prototype with real user data if the work stays internal, or should synthetic data be the default?
