Microsoft-style bundles commonly centralize identity, content, and AI in one vendor-controlled plane; in practice that often means readable workspace data and wide API reach unless you layer extra controls yourself. ChtSafe’s design—client-side encryption optional by policy, keys not escrowed to operators, ShinrAI before inference, and automations limited to temporary derived subkeys and sub-API credentials per task—is meant to reduce that blast radius by construction, not by slogans. Apple’s public Secure AI / Private Cloud Compute narrative emphasizes device-anchored trust and ephemeral, purpose-specific server processing; our hosted and private paths aim at a similar separation of duties even though we are a different product and deployment surface. We spell out what leaves each boundary so you can map this to your threat model rather than compare logos.
