Why Tinfoil?

Verifiable Privacy - Your data is processed inside secure enclaves that even Tinfoil cannot access. Hardware-enforced privacy that you can verify. Drop-in Compatible - OpenAI-compatible API; no need for complex code rewrites. Tinfoil follows the same format as existing SDKs. Transparent Security - All our security-critical code is open source. You can verify that your data was processed in a genuine secure enclave via remote attestation and transparency logs.

What Makes Tinfoil Different?

Traditional AI services process your data on servers that the application provider can access. With Tinfoil:
  • Your data stays encrypted and is only processed inside a secure hardware enclave
  • Even Tinfoil cannot see your data during processing thanks to confidential computing
  • You can verify these claims using cryptographic remote attestation
  • It’s the same OpenAI API format that you already know how to use
