She started her career by working in journalism. First, she worked at a local newspaper, then moved to Gothenburg, where she eventually worked for the Sveriges Television on the Filmkrönikan.[4] In the years 2007–2014, Kapla worked as the director of the Gothenburg Film Festival, then for the next two years served as the program director of its digital streaming service.[2] In the years 2016–2020, she was one of the two editors-in-chief of the journal Ord och Bild.[2][4]
In 2022, Kapla published her second book, Kärlek på svenska,[7] which also consisted of interviews, this time on the topic of love.[2][7] However, Kapla did not conduct the interviews herself and based her book on the work of the filmmaker Staffan Julén instead.[7] The book was nominated for the 2023 European Union Prize for Literature.[2]
