## The brief

EFF examines the tension between encrypted messaging and AI services that process conversations in the cloud. Its analysis says trusted execution environments can offer safeguards but do not preserve the same privacy boundary as keeping messages on participants' devices. The authors call for clear user choices and caution against automatically sending private conversations to external AI systems.
