Cursor Credits / Grok Bot & SpaceXAI

Hey guys have you received this email? Cursor giving free $300 dollars credits?

"Use those to upgrade to Cursor Ultra, then onboard Grok Bot on that Ultra seat. Grok Bot is an AI teammate with its own computer and persistent memory. You can hand it a React Native job, it drives the tools, and it keeps going in the background while you stay on the next screen."
