AI agents inside iMessage with Photon.
We build AI agents that live inside iMessage using Photon's Spectrum framework — no app download, no website, just the conversation your customers already trust.

The short answer
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.
Photon expertise that goes beyond the API call.
We don't just wire up an API call. We understand gRPC stream supervision, Spectrum's tool schemas, and the fallback logic that keeps an agent reachable when iMessage delivery fails.
Spectrum SDK
Open-source TypeScript framework connecting agents to messaging platforms.
Agentic Mini Apps

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.
