Sesame

Sesame creates AI companions with strikingly natural voices and presence, whose conversational partners feel genuinely alive to talk with.

Overview

Sesame made waves with its companion characters, notably Maya and Miles, whose voice conversations are remarkably human: natural pacing, interruptions, laughter and pauses that signal a shift from robotic assistants toward real presence.

The company pairs its voice models with eyewear and device ambitions, aiming at ambient companionship rather than screen-bound chat. Its research focuses on the qualities of conversation that make people feel heard, and its demos drew widespread attention for crossing the believability threshold in voice AI. The quality of small conversational details such as timing and back-channeling is what makes the experience feel uncannily human. Ambitions around ambient hardware suggest companions that live with you rather than apps you open.
