Sesame builds conversational voice AI companions, presented as personal agents and everyday collaborators that help people talk things through. It is aimed at people who want an assistant they can speak with over time rather than a tool that only handles commands. The site focuses on voice presence: emotional intelligence, conversational timing with pauses and interruptions, contextual awareness and a consistent personality. Its research model, the Conversational Speech Model, uses conversation history to produce more natural speech and is trained mainly on English data. The app is available on iOS and Android, a research preview runs in the browser, and eyewear is listed as coming soon. No pricing is shown on the site.
