Your recommendations start becoming more tailored to your unique taste profile as soon as you start rating, even within your on-boarding, Hai is already learning about your preferences. The more preferences you share with Hai, the better your recommendations become!
To improve your recommendations, rate as many items in as many domains as possible, you can even search for specific items to rate. Bookmarking and skipping an item (X icon) also helps Hai understand your taste preferences. Syncing other apps to Hai also gives Hai access to your usage history which will help improve your recommendations.
