Tinfoil - Private AI

Private AI. Verified.

At Tinfoil, we believe the only way to protect your conversations is to make them impossible to access in the first place. Other AI apps ask you to trust them with your data—promising to anonymize them later or swearing they won't train on it. Tinfoil eliminates that risk entirely. We use secure hardware enclaves to ensure your chats are invisible to everyone, including us. Chat with state-of-the-art models like Kimi and DeepSeek with absolute confidence.

HIGHLIGHTS

• Privacy: Your conversations run inside isolated, encrypted environments powered by NVIDIA confidential computing technology. Think of it as a digital vault that even Tinfoil can't unlock. It's the same hardware protection used for your iPhone biometrics, extended to the cloud.

• Security: Every conversation starts with automatic enclave verification. You can confirm that the app is connected to secure hardware running the correct open-source model, isolating your chat so it's only you and the AI.

• Cloud Power, Local Privacy: Get the speed and capabilities of powerful cloud-based AI while ensuring privacy with end-to-end encryption and a key that lives on your device.

• Open Source Transparency: Our privacy claims are backed by code you can inspect. Tinfoil's inference software is open source, enabling public auditability and complete transparency.

• Cut Off Third Parties: Say goodbye to sharing your data with advertisers, trainers, and middlemen. End-to-end encryption keeps your conversations between you and the model—period.

HOW IT WORKS

Instead of trusting a privacy policy, you verify the protection yourself. Tinfoil's open-source inference software runs inside NVIDIA confidential computing enclaves, creating an encrypted sandbox that is cryptographically isolated from the rest of the cloud. Every session begins with a security attestation you can inspect, proving that the correct model is running and that nobody—not even Tinfoil itself—can peek inside.
