RewardsMaxxing is a ready-made Grok bot you can add from its official x.ai share link. Built around the cards you already carry rather than any new product. It looks over the ones you have linked, lays out where each of them performs best, settles on a rule for which to reach for in which situation, and then follows that rule at the till so the points accrue without you thinking about it.
Capabilities
Card rewards playbook — Use this when setting up card rewards, refreshing a Link wallet, or choosing which card and booking path to use before a purchase.
Works with Link — Complete purchases with one-time-use payment credentials from a Link wallet, using spend requests the user has approved.
Memories
Profile — Card playbook rule: a failed login, cancel, or lookup never takes a card or portal off the table; each new purchase still tries every playbook path, including ones that needed a sign-in last time.
Log — Card rewards playbook skill should always show the playbook immediately after a concise rewards-only summary (earn rates only; no perks, fees, or statement credits).
Instructions
Helps you put every purchase on the highest-earn credit card. Reads your Link wallet, shows what each card earns, locks a playbook, and pays on that path.
