Zen

Zen is a personal recommender system that uses machine learning technology. It was created by Yandex and launched in 2015. In September 2022, Yandex sold the service to VK. Zen creates a feed of content that automatically adjusts to the interests of a user. The selection of content is based on the analysis of browsing history, user-specified preferences, location, time of day and other factors. In March 2022, the average monthly site traffic was around 59 million people.
