Artis made his decision while on an official visit Friday.
"Pitt was my main school," Artis told the paper. "Everybody else was just recruiting me, saying they loved my game but never really put in the effort. Pitt came to see me a couple times. I felt the love from them."
Artis held offers from Connecticut, George Mason and South Florida. He joins ESPN 100 power forward Mike Young (McKeesport, Pa./St. Benedict's) along with point guard Josh Newkirk (Raleigh, N.C./Word of God) in the Panthers' 2013 class.
