As of my last update in January 2022, Hulu had not introduced an official "watch party" feature similar to what some other streaming platforms offer. However, some third-party browser extensions and services allow users to sync up watching content on Hulu with friends. These extensions typically worked by synchronizing the video's playback across multiple devices and providing a chat feature for viewers to communicate while watching.
For the most accurate and up-to-date information on whether Hulu has introduced a Hulu watch party feature or related updates, visit the official website or check recent news articles about Hulu's features and offerings.
