# KosherChat

> KosherChat is kosher AI built for Jewish families — available by SMS, web, iOS, and desktop Tether. It uses GHOST (Generative Harm Observation via Subspace Trajectories) for intent-layer safety filtering. Separate products serve other faith communities and schools; KosherChat is the Jewish home product.
