Sesame

Sesame is a pioneering AI research and product company dedicated to creating a future where human-computer interaction is as natural and lifelike as human conversation. The core mission is to build an AI personal companion that can see, hear, and collaborate with users in a deeply intuitive way. This is achieved by focusing on "voice presence"—the quality that makes spoken interactions feel real, understood, and valued, moving far beyond the robotic, neutral tones of current digital assistants.

At the heart of Sesame's technology is its proprietary Conversational Speech Model (CSM), an advanced end-to-end multimodal system. The CSM leverages the history of a conversation, including both text and audio cues, to generate speech that is not only high-fidelity but also contextually and emotionally appropriate. This allows the AI to capture the subtleties of human expression, such as rising excitement, thoughtful pauses, and warm reassurance, making dialogue feel genuine and engaging.

The company has a two-pronged approach: a sophisticated AI companion software and purpose-built lightweight eyewear. The software acts as a brilliant friend and conversationalist, helping you stay informed, organized, and even become a better version of yourself. The eyewear is designed for all-day wear, providing seamless, high-quality audio access to your companion, who can observe the world alongside you and offer assistance in real-time.

How to use Sesame

Currently, Sesame offers a research preview of its technology, allowing users to experience the next generation of conversational voice firsthand. To use it, you can visit the Sesame website and interact with the AI companion through the provided interface. This preview showcases the model's ability to generate expressive and context-aware speech. The process involves engaging in a dialogue where the AI listens and responds, demonstrating its advanced capabilities. The ultimate vision is for users to interact with the companion hands-free throughout their day via the integrated lightweight eyewear, making access to information and assistance completely seamless.
