Download and pilot access

Invitation-only, unpaid, for ten US-adult accounts.

The 30-day review starts at first pilot activation; it does not automatically expire your account. Use the acquisition instructions supplied with your invitation. This page does not offer unrestricted signup or certify artifact availability. Read the funding limits and planned pricing before setup.

iPhone and iPad

The pilot uses TestFlight and requires an Apple device, with iOS or iPadOS 26 or later. The later App Store and paid release are separately gated. No public acquisition link is offered here until the candidate and invitation route are verified.

TestFlight link: sent with your invitation.

Apple Watch currently requires watchOS 27 with a paired iOS 27 iPhone. Conversational CarPlay requires iOS 26.4 or later. Push to Talk and Phone Calls depend on supported iPhone hardware and entitlements. iPad does not originate Phone Calls; companions do not have identical capabilities.

Mac

The pilot targets Apple Silicon Macs on macOS 26 or later, outside the App Store. The selected route is an unlisted Developer ID DMG with notarization and stapling, and signed Sparkle updates. Acquisition, clean install, update and recovery must pass for the named release before its link is offered. The Mac app sells nothing.

Mac download: sent with your invitation.

Ubuntu Linux

The initial pilot includes Ubuntu 24.04 LTS x64. The selected route is a signed APT repository and .deb package. Verified repository addresses and key instructions will accompany the approved candidate; none are advertised here yet. Existing versioned installer routes remain compatible, but do not establish signed APT readiness.

The t2h terminal client and Device Actions service do not promise Linux Calls or connection/public Conversation client parity. Sensitive Approvals and funding use authorized Apple app devices.

Windows

Windows 11 x64 is a later pilot or paid-release addition, unavailable through this page. A signed MSI and its payload, install, update and recovery need verification before acquisition is offered.

After you install

iPhone, iPad and Mac

  1. Choose Coral Courier Cloud. On iPhone or iPad, sign in with Apple, then review the AI provider disclosure. On Mac, choose Sign In with Your iPhone, or create/use a separate passkey account. Apple and passkey accounts are separate identities; an Agent pairing passkey is different from an account sign-in.
  2. Follow guided setup through Name and Colour, available Voice, Access and Notifications, Other Agents, Account funding and Connect. Review actual availability and funding before continuing. Pilot access does not require a real purchase. If the app asks you to pay or cannot connect, stop and contact support.
  3. For an existing Hermes Instance, choose Your Hermes Agent or I have my own Hermes and Add Agent. Use its pairing link, or address and code. On the Instance, hermes coralcourier pair creates a pairing code. Pair each additional device separately, or use an Agent passkey where supported. Pairing help.
  4. Open the Agent's Conversation, send a short text and wait for its first reply. Review Settings › Access on each Apple device before asking it to use that device.

Ubuntu Linux

  1. After installing the approved candidate using your invitation's verified instructions, get the Agent's address and a pairing code from the Apple app: open Settings › Devices, select the intended Agent if more than one is listed, then choose Pair a New Device. You can also ask your Agent for them. Keep the code private.
  2. On Ubuntu, run t2h pair <address> <code>, replacing the placeholders with that Agent address and code. This command takes the address and code separately; do not paste a website pairing URL or its fragment into the address argument.
  3. Review Linux Device Actions locally. t2h access off stops the Agent using this machine; t2h area files off turns off files, with shell and mcp as the other areas. Add -a <name> to select an Agent when several are paired. Apple Settings › Access does not control Linux Device Actions.
  4. Run t2h to open the terminal interface, select the paired Agent and press Enter to open its chat. Type a short message, send it and wait for the first reply. Sensitive Approvals and funding still require an authorized Apple app device.
