Photon (photon.codes) builds Spectrum, a multi-channel agent framework that makes AI agents reachable over real conversation surfaces like iMessage, SMS, and email instead of trapping them in web chat.

About Photon

Photon builds infrastructure for AI agents that operate over real communication channels.

Spectrum is Photon’s open-source multi-channel agent framework, enabling AI agents to communicate through interfaces people already use—such as iMessage, SMS, email, Slack, Discord, and voice—instead of being confined to web chat.

Getting Started

The fastest way to ship is with Spectrum Cloud — hosted infrastructure for platforms like iMessage, with credentials ready in minutes.

1. Sign up at app.photon.codes to get your project ID and secret.

2. Install the SDK:

   bun add spectrum-ts

3. Start your app:

   import { Spectrum } from "spectrum-ts";
   import { imessage } from "spectrum-ts/providers/imessage";
   
   const app = await Spectrum({
     projectId: process.env.PROJECT_ID,
     projectSecret: process.env.PROJECT_SECRET,
     providers: [imessage.config()],
   });
   
   for await (const [space, message] of app.messages) {
     await space.responding(async () => {
       await message.reply("Hello from Spectrum.");
     });
   }

Spectrum also runs fully standalone — you can connect to a local iMessage database, bring your own gRPC endpoints, or build your own platform provider. See the docs for self-hosted setups.
