X Opens Grok in XChat for Premium+ Users
X has integrated Grok into XChat group chats. The help center specifies that Premium+ users can add Grok as a member of any XChat conversation to ask questions. The official account also states that group chats are now smarter, allowing users to directly request answers from Grok within XChat.
Once added, Grok can answer questions, summarize unread messages, create shared reminders, and generate images or videos within the app. The September testing documentation also mentioned time awareness and summarizing chats since joining. During the testing phase, users can call out Grok by name and insert it into conversations like other group members. The official help center refers to this as adding a member rather than opening a separate bot window.
The encryption boundaries are outlined on the product page. Both one-on-one and group chats in XChat use end-to-end encryption, with group messages and media encrypted, and session keys provided to each member. Once images or messages are sent to the Grok tab, the sent version is no longer encrypted, while the content in the original conversation remains encrypted. If Grok is added as a member, X and SpaceXAI can read all messages in that conversation from the time of joining to removal to provide functionality. Group invitation links, group names, and avatars themselves are not encrypted and can be public.
This follows the encrypted chat feature launched earlier this year. The developer documentation states that group chats and one-on-one chats use the same encryption model, rotating session keys when members change. On September 30, the X Chat interface was updated to version 2.169, enabling group management, admin applications, invitation links, join requests, mute settings, pinning, message lifespan, and anti-screenshot settings. On October 2, Elon Musk simply stated that users should ask Grok questions in XChat.
Early use cases were categorized into fantasy sports debates and family group chats. Privacy concerns also arose, as the help center noted that during Grok's time in the group, the platform and model provider could see messages. There has been no announcement regarding the maximum number of group members, generation limits, or availability outside the U.S.
This is a subscription feature, not an advertising space. The buyers are U.S. Premium+ users, while the sellers are X's messaging layer and SpaceXAI's model. The money from the annual fee goes into reasoning and generation, and questions, summaries, images, and videos in the group do not leave the app. Those who benefit are those who want to keep searches and reminders within the group thread. Those under pressure are those who still need to switch to independent chatbots and those who consider family or work groups as default encrypted spaces. Removing Grok will cut off subsequent reading, and the history before joining is not within the reading range promised by the help center.

X's messaging product only integrated group chats and media into end-to-end encryption this year, with developer documentation using session keys, public keys, and signatures to keep X itself out of plaintext. Grok is taking the opposite route this time: the help center stipulates that once added as a member, X and SpaceXAI can read all messages from joining to removal. The September 24 testing already included calling out, inserting comments, reminders, and summaries since joining in the same thread. Encryption is default, and the model is a one-time authorization.
The reasoning costs are covered by the Premium+ annual fee, without charging group members per query. Image and video generation also remains within XChat, not sending users to external model sites. The group interface, just opened on September 30, manages invitations, admins, pinning, and message lifespan. Grok does not have a separate group management interface; it occupies a member seat. Once a seat is occupied, summaries and reminders stick to the message flow, rather than the search box.
Comparable examples include Meta placing assistants in WhatsApp and Instagram inboxes, and Telegram allowing bots in groups but with permissions decided by group owners. OpenAI's consumer entry still primarily relies on standalone applications. X is currently in an expansion phase: encrypted group chats have just been established, and model membership is only open to Premium+ users, with no details on availability outside the U.S. or limits on usage.
This represents a shift in pricing power. End-to-end encryption keeps the platform out of the content, but also blocks the group summary feature. To do unread summaries and shared reminders, plaintext must be handed over to the model provider during the joining period. The subscription fee does not buy higher encryption but rather the temporary right to release encryption. Groups that are unwilling to release it will continue to have only keys, without members who can read chat records.
