Ask @grok in an X reply

Tag @grok under a post on X and Grok answers in the same thread with that post as context. The reply is public.

Call Grok in the thread

1. Open the post or reply you want explained, checked, or continued.
2. Write a reply that starts with @grok, then the ask: explain, verify a claim, summarize the thread, or generate an image tied to the post.
3. Post. Wait for the @grok account to reply in-thread.

You can also open the ... menu on a post and choose Ask Grok when that control is present. Same job: Grok reads the post (and often the image) and answers.

What belongs in the ask

• Point at the claim: “is this true,” “what changed,” “explain the chart.”
• Keep private drafts off this path. Public threads stay public, including any image Grok generates there.
• For a private session with higher limits, open the Grok tab in X, grok.com, or the Grok apps instead.

Pitfalls

• In-thread @grok has been gated to X Premium / Premium+ on some accounts. If the mention does nothing, check your plan, then use the Grok tab or grok.com.
• A Grok reply is a model answer in public. Open the primary source before you treat it as settled.
• Rate limits and plan gates change. If the bot stays quiet, retry later or move the same ask into a private Grok chat.
