Memory

Grok has persistent memory that carries user preferences and context across conversations. **Available on all tiers including free.** Memory is selective and automatic—Grok stores key facts it deems important. Users can turn memory off under Settings → Data Controls, but there is no itemized memory manager listing everything saved. The feature appeared with Grok 3 in early 2025 and behavior can be inconsistent across platforms.
