Annsofi became known as «the little girl with the big voice» when she reached third in the X Factor, and later participated in the Norwegian Eurovision with Alexander Rybak's song I'm with You. With the song, Don't Slaughter Me, she became an official ambassador for Norway’s biggest anti-bullying campaign by the Norwegian Red Cross. Since 2020, she has made up one half of the duo, annsofi & me, whose single, Beauticool, was voted Official Theme Song for Oslo Pride the same year. On February 3, 2023, she released another Rybak collab, with the heartfelt ballad, No More Me and You.
