What does Photon do?
Photon is an open-source framework that lets developers connect AI agents to messaging platforms people already use — iMessage, WhatsApp, Discord, Slack, Telegram, Instagram, and more. Instead of building separate integrations for each app, you write code once and Photon handles the rest. It's a TypeScript library (npm package spectrum-ts) that gives you a unified API for sending and receiving messages, attachments, polls, stickers, and interactive components across all supported channels.
What makes Photon stand out is its flexibility. You can let the framework auto-select the best channel for delivery, or explicitly route messages through iMessage with Telegram as a fallback. It supports event-driven, real-time communication — agents can react to incoming messages by type (text, attachment, etc.) and send rich, structured content. The code examples on the site show how simple it is: a few lines to set up a Spectrum instance, define an agent, and handle messages. Photon also taps into platform-specific capabilities when you need deeper native integrations.
This tool is built for developers who want to deploy AI agents across multiple messaging apps without the headache of maintaining separate codebases. It's especially useful for startups building customer support bots, teams creating internal assistants that work across Slack and Teams, or anyone experimenting with generative AI in chat interfaces. If you're comfortable with TypeScript and want your AI to meet users where they already chat, Photon is a practical, well-designed solution.
