Bring Agents to the Interfaces Millions Already Use.

Spectrum is an open-source framework that connects your agents to iMessage, Telegram, WhatsApp, Slack, Discord, Instagram, and other interfaces people use every day.

Cross Channel

const spectrum = Spectrum(providers: [...], config: {...})
const agent = new Agent()

// Handle incoming messages by type
spectrum.onMessage(async ({ space, message }) => {
  switch (message.type) {
    case "text":
      const response = await agent.generate(message.content)
      await space.send("Hello World", attachment(...))
      await space.send(response)
    case "attachment":
      await message.react("like")
  }
})

// Auto-select the best available channel for delivery
await spectrum.send("+123456789", sticker(...))

// Explicitly route through iMessage with Telegram as fallback
await spectrum.send("+123456789", imessage().fallback(telegram()), poll({...}))

Manifesto

What we do at Photon is taking away yet another barrier of usage of Agents. We believe we have a chance to change the way people think about Agents. We call it Agents for the rest of us because Agents aren't just for the elite; we think we have a chance to make a difference.
