Wekinator is software for real-time, interactive machine learning. Wekinator facilitates the use of machine learning as a prototyping and design tool, enabling composers, musicians, game designers, and makers to create new gestural interactions or semantic analysis systems from data.

Authored by Dr Rebecca Fiebrink, Wekinator has been downloaded over 3000 times and used in dozens of computer music performances utilising new musical instruments built with machine learning.
