XChat is an integrated instant messaging feature within X (formerly Twitter) designed to offer various communication options, including voice and video calls, file sharing, image sending, voice messages, and vanishing messages. It is accessible on mobile for both free users and X Premium subscribers, although some advanced features require a subscription. XChat includes encryption, disappearing messages, and the ability to send any file type. Unlike existing direct messages (DMs) on X, XChat offers more advanced features such as unsending messages and group chats. Security is emphasized, with XChat built on Rust and utilizing a "Bitcoin-style encryption system," though it does not guarantee end-to-end encryption. Key features of XChat include disappearing messages, message unsending, group chats, and audio/video calls without the need for a phone number. Currently in beta, XChat aims to enhance connectivity for brands and digital marketers on the platform. The unique advantage of XChat is its integration with X, allowing for a centralized experience combining social media and messaging functionalities.
