Questions, answered

A private research assistant. Attach documents, ask questions, and pay with shielded Zcash. No account, no email, no card.

Yes, in beta, with limits. Your browser verifies a Tinfoil enclave and encrypts your question to it, so ZCode's server can't read it. The enclave has to read it to answer, so you're trusting its hardware and code, as well as the code this site delivers. The privacy page has the details.

Yes, in beta. Top up the Starter pack with shielded ZEC from a wallet such as Zodl; credits arrive after 3 confirmations, usually a few minutes. The larger pack opens after an independent security review.

DeepSeek V4.1 Flash, running in a Tinfoil enclave. The model may change; the app always shows which one is answering.

Yes. With Web switched on, the model can search through Tinfoil's private search and cite its sources. The search query leaves the enclave to the search provider (Exa, under a zero-retention agreement), with personal details masked first; nothing links it to you. Switch Web off to keep everything inside the enclave.

Yes. A new session starts with 5 free credits, enough for a handful of answers. Top up with shielded ZEC when they run out.

In your browser, and in an encrypted backup we can't read. The key that unlocks the backup never leaves your device.

If you still have a device signed in, open Menu → Recovery code and save it again. If you've lost the code and every device, nobody can recover the session.

No. ZCode's server can't read your questions or documents: they're encrypted in your browser, and it sees only their size.

No. It's an independent project, not affiliated with or endorsed by the Electric Coin Company, the Zcash Foundation or NVIDIA.

No. Credits are a prepaid balance for answers, not a tradable asset.
