The default place to talk. From personal plans to customer conversations, iMessage is already where people coordinate everyday life - across friends, family, teams, and customers.

No app. No onboarding. Tap a link or text a number, and your agent opens directly in iMessage. No app to download, no signup to complete. Your agent is on the best platform people open every day.

Feels personal. Because it is. iMessage is where people already have their most important conversations. When your agent shows up there, it makes every interaction feel natural, familiar, and human.

The interface everyone knows. Everyone already understand how to use iMessage. That means no learning curve for users and a way to reach customers far beyond the AI bubble.

Spectrum delivers the deepest set of native iMessage capabilities ever built for agents.

Photon delivers reliable, low-latency agent execution and messaging infrastructure.
built to scale with real user demand.

Text, styled your way. Your agent can send and receive beautifully rendered iMessage text - with bold, italic, rich links, text effects, and bubble effects that make every message feel native to the conversation.

Photos. Files. Instantly shared. Send photos, Live Photos, videos, documents, and multi-image carousels directly inside iMessage, presented natively so they feel instantly familiar and ready to open.

React. Relay. Relate. Let your agent respond with native iMessage reactions, giving users instant feedback without sending another message. Sometimes a tapback is all the conversation needs.

Replies, threaded beautifully. Your agent can reply directly to a specific message, keeping side questions, follow-ups, and “by the way” moments connected to the right part of the conversation.

Typing… telegraphed. Show a native typing indicator while your agent works, so users know a response is coming even when reasoning, searching, or taking action takes a little longer.

Contacts, shared in a tap. Show users a native contact card they can add in one tap, so your agent appears with the right name, photo, and brand identity every time it messages.

Voice notes, naturally. Your agent can send voice note bubbles directly in iMessage, so spoken responses feel familiar, personal, and ready to play.

Location, live when needed. With user permission, your agent can receive real-time location updates in iMessage, enabling proactive help for travel, delivery, meetups, safety, and any task tied to where someone is right now.

Better in groups. Bring agents into iMessage group chats, invite the others, and shape the space with native group names and photos so every collaboration starts organized.

Ask. Vote. Done. Your agent can send voice note bubbles directly in iMessage, so spoken responses feel familiar, personal, and ready to play.

iOS 26 Required

Backgrounds with personality. Set custom iMessage conversation backgrounds so every thread feels recognizable, polished, and built for your agent.

iOS 26 Required

Mini apps, inside the message. Your agent can generate interactive UI inside iMessage, turning complex tasks into native iOS-style experiences users can complete right in the thread.

The same number. Now with calls.

The same line people message can now be the one they call. Your agent can answer,
call back, and continue the conversation in iMessage, all from one number.

Channel orchestration, built in

Use the Omni plugin to move seamlessly between iMessage and voice. Spectrum handles the routing, context, and handoff logic, so your agent can text during a call, call from a thread, and keep the conversation continuous.

Works with SIP

Bring your existing voice infrastructure. Connect Spectrum calling to SIP-compatible platforms like LiveKit and Retell, and give your agent one number for both iMessage and calls.
