Private AI

Pryv leverages secure enclave technology and Trusted Execution Environments (TEEs) that keeps your AI prompts private, all metadata remains secure and never reaches the models. No tracking, just trusted AI.

Fingerprinting techniques

VPNs fall short against browser fingerprinting. Our TEE-secured AI proxy rewrites traffic at the source, stripping headers and blocking scripts—erasing nearly every trace before it ever reaches OpenAI

Fingerprinting

Techniques

Swapping your IP with a VPN does very little to mute modern browser-fingerprinting - almost every higher-layer clue still arrives unchanged. A header-scrubbing AI reverse-proxy that terminates TLS inside a TEE erases nearly all of those clues before traffic reaches a downstream service such as OpenAI, because the proxy rewrites the network envelope and serves no client-side JavaScript that could probe the browser.
