xAI adds a ‘memory’ feature to Grok

Elon Musk’s AI company, xAI, is slowly bringing its Grok chatbot to parity with top rivals like ChatGPT and Google’s Gemini.

Wednesday night, xAI announced a “memory” feature for Grok that enables the bot to remember details from past conversations. Now, if you ask Grok for recommendations, it’ll give more personalized responses — assuming you’ve used it enough to allow it to “learn” your preferences.

ChatGPT has long had a similar memory feature, which was recently upgraded to reference a user’s entire chat history. Gemini, too, has persistent memory to tailor its replies to individual people.

“Memories are transparent,” reads a post from the official Grok account on X. “[Y]ou can see exactly what Grok knows and choose what to forget.”

Grok’s new memory feature is available in beta on Grok.com and the Grok iOS and Android apps — but not for users in the EU or U.K. It can be toggled off from the Data Controls page in the settings menu, and individual “memories” can be deleted by tapping the icon beneath the memory from the Grok chat interface on the web (and soon Android).

xAI says that it’s working on bringing the memory feature to the Grok experience on X.
