Grok Bot Reads and Replies to X Chat DMs, Can Become Android’s Default Assistant

What happened

Palmer walked through 12 changes in the five-minute video, spending the most time on the X Chat feature. “Bot can now read your X chat DMs and respond,” he said in the video, calling it a feature that had been “asked for like a million times” and adding that limits are in place so “you can’t spam people.” Per Tesla North, Palmer did not say whether a Bot needs the user’s approval before each reply goes out.

The video also confirmed that users can tag @bot in any X thread and it will “do whatever you ask it to” — for example saving a post or explaining something just seen on the timeline — with the X plugin installed and configured first. On Android, Grok Bot can now be chosen as the phone’s default assistant, a day after it gained one-press access through the iPhone’s Action Button; voice calls keep the previous call and its full transcript if you call back within 30 minutes. Elon Musk had already pointed people toward the feature on October 16, writing that users should ask Grok Bot to connect to their X DMs — “Best way to use it.”
