X’s new DM feature, XChat, has begun rolling out to beta testers.

Axar.az reports, citing TechCrunch, some X users who pay for the platform’s subscription product have reported that they can access XChat, while reverse engineer Nima Owji confirmed that the new messaging system appears to be ready to ship.

XChat is intended to be a more robust version of X’s existing DM (direct messages) feature, which is a holdover from before Elon Musk’s acquisition of Twitter.

Some features that have been rumored to be part of XChat include group messages, end-to-end encryption, vanishing mode, the ability to mark messages as unread, and file sharing. Messages also appear to be secured behind a four-digit passcode.

X announced on Thursday that it was pausing work on its encrypted DM feature, which could be related to the impending release of XChat, since this new system would render the existing DM interface obsolete. Paid subscribers on X have had access to a limited version of encrypted messaging for two years.
