Tinfoil

Jules Drean, Tanya Verma, and Sacha Servan-Schreiber built Tinfoil because they got tired of every AI chat leaving your conversations exposed to third parties, advertisers, and god knows who else. Every ChatGPT, Claude, and Gemini prompt you've ever typed is being stored, analyzed, and used to train models you never consented to. Tinfoil says nah, your prompts stay between you and the model—end of story.

They do this by leveraging NVIDIA GPU hardware security features—think confidential computing, encrypted VRAM, the kind of stuff that makes your data untouchable even if someone physically grabs the server. It's not just privacy theater. It's architecture-level isolation built into the silicon. You get a private AI chat interface for $20/month, or if you're building something, their API gives you $5 in free credits to start—plug it into your app and your users' prompts never leave your control.

The pitch is simple: if you're working with sensitive data—customer support, medical, legal, whatever—regular AI tools are a liability. Tinfoil is the alternative that doesn't make you choose between AI power and privacy. They're on Product Hunt if you want to try it.
