Online Safety is Broken.

Today’s threats from AI-generated CSAM to autonomous scams are scaling faster than legacy tools can stop them. Safety shouldn’t be a black box or a luxury reserved for tech giants. We exist to make safety infrastructure open, shared, and auditable for everyone.

Our tools cover the full safety lifecycle from real-time detection and investigation to scaled review and enforcement.
