Sesame AI
Creating Digital Companions for Natural Conversations
Sesame AI is an advanced voice technology platform developed by the Sesame team, focusing on creating digital companions capable of real conversations. How do we know when someone truly understands us? It is rarely just our words—it is in the subtleties of voice: the rising excitement, the thoughtful pause, the warm reassurance.
Why Choose Sesame AI
Our core technologies and features make Sesame AI stand out in the voice technology landscape
Achieving Voice Presence
At Sesame, our goal is to achieve 'voice presence'—the magical quality that makes spoken interactions feel real, understood, and valued. We are creating conversational partners that do not just process requests; they engage in genuine dialogue that builds confidence and trust over time.
Emotional Intelligence & Conversation Dynamics
Today's digital voice assistants lack essential qualities to make them truly useful. Sesame AI understands emotional contexts with natural timing, pauses, interruptions and emphasis. Without unlocking the full power of voice, they cannot hope to effectively collaborate with us.
Contextual Awareness & Consistent Personality
Voice is our most intimate medium as humans, carrying layers of meaning through countless variations in tone, pitch, rhythm, and emotion. Our assistants adjust their tone and style according to the conversation context while maintaining a coherent, reliable and appropriate presence.
How to Use Sesame AI

No Need to Connect Your Account
No need to create a Sesame AI account and connect it to your devices. Our platform supports a variety of devices and operating systems.
Customize Your Digital Companion
Tailor your voice assistant's personality, voice style, and interaction mode according to your preferences. A personal assistant who speaks only in a neutral tone has difficulty finding a permanent place in our daily lives after the initial novelty wears off.
