F.R.I.D.A.Y.

F.R.I.D.A.Y. is a natural-language user interface created by Tony Stark, designed to work with his Iron Man armor. She served as Stark's main user interface computer system during the final battle between the Avengers and Ultron in Sokovia and to find information about Helmut Zemo. In contrast to J.A.R.V.I.S.'s voice code which was patterned after a male English accent, F.R.I.D.A.Y.'s is patterned after a female Irish one.

FRIDAY's abilities seem to be an upgraded version of J.A.R.V.I.S.' She is fully capable of controlling Iron Man suits as well as assisting Tony in their operation and controlling whole vehicles, like her predecessor, but she displays new abilities as well. She is capable of monitoring the entire internet, able to easily hack into government databases, partially override the Raft's security systems and analyze fighting styles for weaknesses to exploit.
