About Photon
Photon is a frontier open-source lab focused on human–AI interaction, and we are building two core products: Spectrum and Photon SDK.
Spectrum is the connection layer that brings AI agents into messaging apps, social platforms, and hardware. You can interact with an agent as easily as sending a text or calling a phone number.
Photon SDK is the interaction layer - a developer toolkit for building agents that natively support messaging apps with rich, high-quality interaction capabilities.
Culture & values
We call it Agents for the rest of us because Agents aren't for ordinary people.
