About

I'm the co-founder of Tinfoil working on building private AI using secure hardware. Previously I finished my PhD at MIT where I worked on theoretical and applied cryptography. At Tinfoil, I'm working on building a future where people can use powerful AI models with full privacy - nobody should be able to read your AI conversations. I believe that privacy guarantees should be written in code, not in legal policies and so everything at Tinfoil is built in a way that is verifiable through secure hardware and made open source.

Tinfoil - AI chat and API that keeps your conversations fully private

Don’t want OpenAI seeing all your conversations? We don’t either. That’s why we built Tinfoil - an AI that keeps your conversations strictly between you and the AI model, everyone else is locked out. It’s like a local AI but running in the cloud, using secure hardware. Tinfoil leverages hardware security features available on NVIDIA GPUs to deliver verifiable privacy. No pinky promises required: you can check for yourself that your conversations are end-to-end private.
