Jarvis is best known as the artificial intelligence assistant created by Tony Stark in Marvel's Iron Man films, where he manages systems and displays information on command. Online, short Jarvis voice memes copy that dynamic, with a user giving the assistant a blunt order for comedic effect. This version focuses on the put it up command, a setup that works whenever a creator wants to present something as proof. Its popularity comes from instant recognition of the assistant premise and the universal joke of demanding evidence appear immediately.
