CalAI founder Zack Yadigari introduces Persona AI assistant and wearable band

Zack Yadigari has introduced Persona, a new AI assistant following CalAI, along with the Persona Band, a wrist- or face-activated interface designed to reduce reliance on phone screens. The product is intended to learn users’ habits and proactively arrange tasks such as an Uber after a flight, while also canceling subscriptions, negotiating bills, or ordering a familiar DoorDash meal.

The band’s microphone is said to activate only under the user’s control rather than continuously listening. It is launching in three materials and four colors, with preorders open. A potential adoption barrier is that users must purchase the hardware and wait for it to ship, while the product’s utility beyond a phone remains uncertain.
