⚙️ How it works

Marketplace description

Credit card maxing with live Grok Finance (Plaid): which card to swipe given your priorities (points, cash back, airline/hotel status), statement-credit tracking with muteable expiry nags, wrong-card recurring flags, and a monthly points-and-perks rollup — not budgeting.

One tap copies Trevin Chow's full setup text (4 standing instructions, 2 skills, 3 routines), with credit and a source link, so you can read it or paste it into your own Grok Bot.
