Google added persistent memory to Private AI Compute. Data stays encrypted in cloud storage. Cryptographic keys remain only on user devices. A secure enclave decrypts data temporarily for processing. The system re-encrypts and stores updates immediately. Devices verify server software authenticity before sending data. Google published a tamper-proof public record of the server software. An independent cybersecurity firm audited the technical methods. The update enables seamless AI assistance across devices. Trust relies on transparency and verifiable protections.

What changed

Private AI Compute was stateless and wiped all context after each task.

What it unlocks

AI assistants can now retain and access long-term context across devices.

What you need to act on it
