TikTok employs artificial intelligence (AI) to analyze users' interests and preferences through their interactions with the content, and display a personalized content feed for each user.[80][81] TikTok has an algorithm in which they process the user's preferences based on the videos they "like", comment on, and also how long they watch the video. Compared to conventional consumer algorithms such as those of YouTube and Netflix with a list of recommended videos, TikTok interprets the user's individual preferences and provides content that they would enjoy.[82][failed verification][better source needed]
