The core activity of Pro-Zurituutsch is the promotion and dissemination of the Zurich German language and literature, particularly through the development and use of a phonetic spelling system, known as the "Zurituutsch spelling system". This includes the publication of texts, radio plays and other media in Zurich German, providing information and guidance on pronunciation and language usage, as well as supporting artists and projects that promote the Zurich German language and culture.
