The short answer

Under the hood · How it works

Photon's Spectrum framework gives agents a way into the messaging interfaces people already use every day — iMessage above all. There is no official Apple iMessage bot API, so most teams choose between sales-oriented APIs, fragile Mac-based bridges, or Photon's managed infrastructure. Photon handles the persistent gRPC connection, message routing, and SMS/RCS fallback so the agent never needs to touch a Mac or maintain a webhook.

Bolder uses Photon when a client wants an agent to live where their customers already text — not in a new app they have to download. The Spectrum SDK is open source and TypeScript-only, deploys to iMessage, WhatsApp, Telegram, Slack, and Discord from one codebase, and supports sending full agentic mini apps (menus, booking flows, mini games) directly inside an iMessage thread.

The conversations that bring iMessage agent projects to Bolder.

Real scenarios that bring Photon-powered iMessage agents to Bolder. If one sounds familiar, we've built it before.

iMessage Concierge & Booking Agent

An agent that takes reservations, answers questions, and confirms bookings entirely inside iMessage — no app download required.

AI Matchmaking & Community Agents

Agents that connect users, run conversations, and manage group chats natively inside iMessage at scale.

In-Chat Mini App Commerce

Send a menu, a checkout flow, or a mini game directly inside an iMessage thread — no website or app needed.

Customer Support Agents on iMessage

Support agents that answer, escalate, and resolve tickets where customers already text — with SMS/RCS fallback built in.

Voice-to-Text Continuity Agents

Agents that move seamlessly between a phone call and an iMessage thread, continuing the same conversation across channels.

Multi-Channel Agent Deployment

Write agent logic once and deploy across iMessage, WhatsApp, Telegram, and SMS from a single Spectrum integration.

Why Photon

When Photon is the right call.

Photon is the right call when an agent needs to reach customers exactly where they already have their most important conversations.

Native iMessage Apps, no download required.

Send menus, booking flows, and interactive UI directly inside an iMessage thread — no app download, no website redirect.

No Mac. No webhook. Just a persistent stream.

Spectrum runs as a persistent gRPC stream. No webhook, no public URL, no Mac relay required to keep an agent live.

One agent, every channel that matters.

Write agent logic once and reach iMessage, WhatsApp, Telegram, Slack, and Discord from a single Spectrum integration.

An agent can text during a call and call from a thread, using the Omni plugin to connect to SIP platforms like LiveKit and Retell.
