Tessera - Car Black Box

Tessera is a black box for your car. It records the road continuously, detects incidents, and assembles a cryptographically signed evidence package — video, motion, and GPS — entirely on your phone. No account. No cloud. No subscription, ever. WHAT MAKES IT DIFFERENT • Tamper-evident: every incident is sealed with a hardware-backed signature and a C2PA content credential. Anyone can verify it — no trust in us required. • Private by architecture: footage, location, and telemetry never leave your device. There is no server. The app works in airplane mode. • AI that sticks to the facts: the incident narrative is generated on-device and only ever states what the signed telemetry shows. FREE • Continuous loop recording with automatic storage management • One-tap and "Hey Siri" clip saving • Live speed readout and a battery-friendly night mode ONE-TIME UNLOCK — THE INCIDENT ENGINE • Automatic crash & incident detection with adjustable sensitivity • Signed, independently verifiable incident dossiers • On-device AI narrative and license-plate capture • Court-ready export: video, telemetry, signature, and PDF report No subscription. No data business. Your evidence, yours alone.
