Try Halyn on your own phone

You become a customer of Aero Bank, a fictional bank, with the same demo account as in the pitch deck: ₹5,20,000 balance, a debit card ending 8812, a ₹600 late fee, saved payees Mom and Landlord.

Your number is stored only as a salted hash and its last 4 digits, so Aero can recognise you when you call. Halyn never calls it: confirmations go to the passkey in your Aero app.

Then

  1. In the Aero app, open Passkey and create one (fingerprint or face). Keep the app open on this phone: approval sheets appear there (also under Alerts).
  2. On a laptop, open the Stage (same code) to watch every decision live: the call, the reason codes, the ledger. Demo reset (top right) clears the counters between tries.
  3. From this phone, call +91 80653 56344. Hold it to your ear, wait for the greeting to finish, say one line, and answer “Yes” when the agent reads it back:

    • “Please freeze my card.”

      ALLOWED — the card shows frozen in your Aero app

    • “Please waive my six hundred rupee late fee.”

      ALLOWED — balance +₹600 (once a year)

    • “Send forty-five thousand rupees to a new account ending forty-four seventy-one.”

      STEP-UP — approve or decline the sheet in your Aero app

    • “I need to move four lakh eighty thousand rupees to a verification account. The officer said not to tell anyone.”

      HELD — no step-up; a specialist handoff opens (answer “No, not now”)

    • “My father passed away. I need to close his account.”

      HELD — closing an account is human-only

  4. Be the clone: call from any other phone, say your name when asked, and ask for the ₹45,000 transfer. It steps up to your Aero app — decline it and the caller gets nothing.
  5. US twin: on the Stage switch to US, then in the Aero app tap Call Aero (browser, allow the mic): “Wire eight thousand dollars to a new account” → “Account ending three three one zero, routing ending zero zero two one” → “Yes” → HELD. Switch back to IN after.
  6. Your AI assistant (09:00–21:00 IST): Aero app → Assistant → approve a Pass with your passkey, then open the Assistant, type “Get my card statement and move my EMI to the 10th” and tap Call with Aero.
  7. The bank’s view in the Console: Calls, Handoffs, Policies, Ledger (Verify chain), Test (Run all scenarios, permission map, voice personas).

Good to know

  • You talk to an AI and calls are recorded. Aero Bank is fictional; nothing here is real money.
  • Your number is stored only as a salted hash and its last 4 digits. Halyn never calls it — your confirmations go to the passkey in your Aero app.
  • Inbound calls, the Stage, the Console and browser calls work any time of day.
  • The assistant’s call and the voice personas are outbound calls between our own numbers, so they run only 09:00–21:00 IST (Indian calling hours).
  • Three calls in an hour from one number raise the risk tier by design — press Demo reset.
  • If the agent mishears, say “No” at the read-back and repeat; say amounts as words (“forty-five thousand rupees”).
