Cursor’s upcoming AI dog. An artificial intelligence that steps off the screen and into the room.
He
More than an ordinary robotic dog.
The idea behind Rex is an AI companion that feels alive, responsive, and capable of evolving alongside its owner. With artificial intelligence at the center of his design, Rex could communicate, recognise situations, respond to people, and learn new behaviours.
His name is simple: Rex. The technology behind him is anything but.
Interacts
Rex is envisioned to sense and respond to the world around him, rather than waiting behind a screen for a prompt.
Learns
Experience is the input. Rex is designed to pick up new behaviours from the situations and people he encounters.
Evolves
A personality that develops over time, so the companion you live with in year two is not the one you unboxed.
Evolutionizing
the AI world.
A future where AI becomes more personal, interactive, and present in everyday life.
Instead of asking an AI to perform a task through a computer or a phone, people could simply interact with an intelligent physical companion. The launch could introduce a new category of AI products, where intelligent systems are not applications or chatbots, but companions that act in the real world.
If Rex delivers on that vision, he could become an important step toward that future.
