Grok Explain This
Grok Explain This, also known as Grok Is This Real?and Grok AI "Explain This Post" Feature, refers to a feature on Twitter / Xpowered by Grok AI, which provides users with an explanation of posts and memes shared on X, often using a humorous and conversational tone. The feature was added on X in December 2024, but later, in April 2025, users were able to tag @Grok in any tweet asking the AI to "explain this post," which spawned backlash and mockery for people who were overly relying on the tool to explain content on the platform. "Grok explain this" and similar variants subsequently became acatchphraseand were then featured in various memes.
