Priver AI is a personal AI companion device and accompanying software that store a user's accumulated AI memory on hardware the user controls rather than in a provider's cloud. Worn or carried as a pendant, clip, or wristband, the device captures events through onboard sensors and a microphone and converts raw data into a private event-graph inside a hardware-rooted secure enclave. A sensor-side privacy boundary prevents raw camera, microphone, and biometric data from leaving the device. The memory stays coherent across the user's paired devices through cryptographically attested coordination, without sharing raw data. External AI systems cannot read the memory unless they pass a hardware attestation gate and cryptographically accept the user's retention and use terms, with per-service transformation limiting cross-service correlation. A physical control deletes memory, propagating deletion to connected systems and recording it in a tamper-resistant audit log. Encryption keys are generated in-enclave and cannot be exported.
