## What it is
Spectrum (by Photon) is an open-source TypeScript framework for building AI agents that communicate over real messaging interfaces like iMessage, WhatsApp, Telegram, SMS/RCS, Slack, Discord, and voice. It provides a unified SDK with pluggable providers, a runtime for handling inbound messages, and optional hosted infrastructure (Spectrum Cloud) or fully self-hosted setups.

## Use cases
- build an AI agent that replies over iMessage
- connect a chatbot to WhatsApp Business and Telegram
- run one agent server across multiple messaging channels
- send SMS with iMessage fallback routing
- build a Telegram bot with webhooks in TypeScript
- self-host an agent connected to a local iMessage database
- add voice call support to an AI agent

## When to choose
- you want agents reachable on native messaging apps instead of web chat
- you need one unified API across iMessage, WhatsApp, Telegram, and SMS
- you want a batteries-included TypeScript SDK with managed or self-hosted options

## When to avoid
- you only need a simple web chat widget
- your project is not in the JavaScript/TypeScript ecosystem
- you need channels Spectrum does not yet support and cannot build a custom provider
