What is the name of Iron Man's AI assistant?

The story behind the answer

The name of Iron Man’s AI assistant is J.A.R.V.I.S. Tony Stark created the artificial intelligence to manage his home, laboratories, security systems, and Iron Man suits. The name is an acronym for “Just a Rather Very Intelligent System,” although the films rarely emphasize the expanded form.

J.A.R.V.I.S. first appears in Iron Man (2008), where it helps Tony operate and refine his armor. Unlike the human Edwin Jarvis from Marvel Comics, the MCU version is a computer program voiced by Paul Bettany. The character’s calm, formal manner became one of the recognizable parts of Tony’s technology.

In Avengers: Age of Ultron, Ultron attempts to destroy J.A.R.V.I.S., but the AI survives by dispersing itself through the internet. Tony and Bruce Banner later use its programming as the foundation for Vision, giving J.A.R.V.I.S. a physical body. Afterward, F.R.I.D.A.Y. becomes Tony’s primary assistant, which is why the two names are sometimes confused.
