Description

Checkout court is a browser extension that puts your online purchases on trial. When you click checkout, the extension blocks the button and summons you to a short AI-powered courtroom where you must defend the purchase. The AI knows your savings targets, spending limits, and progress toward your goals, and uses that information as evidence during the trial. Acting as judge and prosecutor, it questions whether the purchase fits your financial plan, challenges weak justifications, and weighs the cost against what you’re trying to save for. If your case holds up, the checkout is unlocked. If not, the verdict is to reconsider. By turning checkout into a quick courtroom debate, Checkout Court helps ensure every purchase stays aligned with your long-term financial goals.
