Requires the free TestFlight app and iOS 17+. On first launch the app downloads an AI model (~2.5 GB) — use Wi-Fi.

Try it in a minute

  1. Open Sovereign Mind and tap Try Demo Mode — no account required.
  2. Onboarding walks you through setup. Download an AI model — Ministral 3B is recommended (~2.5 GB, Wi-Fi).
  3. Download the knowledge base — the Robot Ross ATF wiki, a sample set of documents the assistant answers from.
  4. Choose a persona — try Field Engineer for a hands-on, technical feel.
  5. Start asking questions — answers are grounded in the documents and cite their sources. For example:
    • “What steps does a drawing job go through?”
    • “What does the readiness check verify before a job runs?”
    • “How does Robot Ross handle calibration?”
  6. Explore: browse the source documents in the Wiki tab, and try switching models in Settings — Apertus is a Swiss-made model.
  7. Try the submarine test 🤿 — turn on Airplane Mode and keep chatting. Everything keeps working: the model and your documents run entirely on the device, with zero network.

All inference runs entirely on-device on Apple Silicon. Zero cloud egress during conversations.

What you need

iPhone with iOS 17+ Free TestFlight app ~3 GB free storage Wi-Fi for the model download
