Every question you ask a chatbot reveals who is asking and what. ScrambleAI separates the two by engineering: questions travel through five mixnet hops, credit is bought once and spent as blind-signed coins, and your history never leaves the device.
Testnet build 0.4.6 · built on the Nym SDK · no account, no e-mail — a 24-word phrase is all you keep.
Not in the app stores yet. Desktop builds are direct downloads (the macOS one signed and notarised by Apple), iPhone comes through TestFlight, Android needs sideloading — and Windows still shows a warning on first launch. Every download has a checksum you can verify.
Testers don't get a pre-funded seed (we would know it) and the server has no special faucet path (nothing to remove later). Instead this page pays the invoice your app created — on the Nyx testnet, with the memo the app shows you. Every tester runs the real purchase flow end to end.
Honest note: the faucet knows memo ↔ invite code, the server knows memo ↔ account, and both are ours — in this test, a purchase is linkable to a tester. Real purchases on mainnet are not routed through anything like this.
Your identity and your questions. The app talks to the ScrambleAI server only through the Nym mixnet (Sphinx packets, five hops, cover traffic) — the server has no public address at all. Credit is bought once as an account top-up and then withdrawn as blind-signed coins; a coin spent on a question cannot be linked back to the purchase that funded it.
The builds are not signed by a store, so the checksum is your proof that the file is the one we published. Copy the line for your system into a terminal — it prints OK (macOS, Linux) or True (Windows) when the download matches.
