We're rethinking human-AI interaction from first principles to be more natural, enabling the next generation of conversational AI products.

Today's AI conversations feel constrained because they rely on a turn-based interaction model—speak, wait, listen, repeat. Real human dialogue doesn't work this way. It's fluid, overlapping, and full of real-time feedback. True conversational fluency requires the ability to interrupt, provide instant reactions, and engage in the dynamic back-and-forth that characterizes authentic communication.

We're building a full-duplex conversational speech model and developer-friendly SDKs for natural, simultaneous two-way communication with AI agents.
