Private AI for health questions
Ask the health question you won't say out loud.
Symptoms, lab results, medications, the thing you've been worrying about - clear answers from frontier AI with your identity stripped from every message. Not tied to your name, your insurer, or your search history.

Your health data is a product
Your health questions are nobody's business model.
The most sensitive questions you'll ever type are about your body. Asked in the usual places, they become ad-targeting signals and server-side records tied to your name.
Search engines turn symptoms into ad profiles
Google a condition once and watch it follow you around the internet for weeks. Your health worries become a targeting signal that gets bought and sold.
Chatbots file it under your name
Health questions to mainstream AI sit on someone's servers, tied to your account and IP - among the most sensitive records that exist about you, one breach from daylight.
The questions people actually bring here
Here's how OpenGradient is different
Clear answers. No record of who asked.
Drop in the lab report
PDFs, scans, doctor's letters - uploaded through the same anonymous pipeline as your chats, never tied to your identity.
Anonymous by architecture
Oblivious HTTP relays and secure enclaves split who you are from what you ask. Not a policy promise - a protocol.
How the architecture worksSecond opinions on tap
Run the same question past ChatGPT, Claude, and Gemini - different models, different angles, same privacy.

The anonymity layer
Three layers between you and the question.
Not a policy promise - a protocol. No single party, including us, ever holds both your identity and your question.

Anonymized by Oblivious HTTP
Network relays split who you are from what you're asking. No one sees both.
Unlocked only in a secure enclave
The model reads your prompt inside attested hardware that never learns who sent it.
