An AI chat with verified privacy. The only way to protect your conversations is to make them inaccessible to anyone in the first place. Other AI applications ask you to trust them with your data, promising to anonymize them later or telling you they won't train on it. Tinfoil is built to prevent data leakage from the get-go. All our models run inside secure hardware enclaves that ensure your chats are private to you and invisible to everyone else, including Tinfoil. You can chat with state-of-the-art open-weight models without worrying about who else can see your conversations. THE HIGHLIGHTS • Your conversations are exclusively processed 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 cloud GPUs that run powerful large models and agents. • Every conversation starts with automatic enclave security verification. You can confirm that the app is connected to secure hardware running the correct AI model, isolating your conversation so that it is only between you and the intelligence on the other end. • You get the speed and features of the most powerful cloud-based AI services while getting the privacy equivalent of having a local model running on your phone. • All our privacy claims are backed by open-source code you can inspect, enabling public auditability and complete transparency. Visit https://github.com/tinfoilsh/ • Stop sharing your data with advertisers, model labs, and data brokers. Tinfoil 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 and the world. Every session begins with a security attestation you can inspect in the Verification Center, proving that the correct model is running and that nobody—not even Tinfoil—can peek inside it. You can read more about all the technical details in our documentation: https://docs.tinfoil.sh/verification/secure-enclave-primer In summary, you get: • End-to-end encryption and privacy from everyone, including Tinfoil. • The latest and most powerful open-source models. • Fully verifiable privacy through open-source code transparency, secure hardware, and public auditability.
