Buy-Box

Buy-Box gives ChatGPT a saved, structured list of what you want to buy, so you stop re-explaining yourself every time you shop.

What it does:

• Saves a buy box per category: homes, cars, rental properties, or any freeform category.
• Lets you add, change, or remove individual criteria (max price, must-haves, dealbreakers, preferred brands) without retyping the whole list.
• Scores and ranks listings you paste or find against your saved rules. Listings that break a hard limit or contain a dealbreaker are excluded and the broken rule is named. Anything a listing does not state is marked unknown, not passed.
• Exports a buy box as readable Markdown.

Who it is for: home buyers, real estate investors and wholesalers, car shoppers, and anyone who shops with AI and wants consistent criteria across chats.

Limitations:

• Buy-Box does not search the web, buy anything, contact sellers, or make offers. It only stores your criteria and scores listings you provide.
• Scoring is rule-based on the fields a listing states; verify unknowns with the seller.
• Sign-in with a Google account is required. Each account sees only its own buy boxes.
• Do not store health details, account numbers, or passwords in a buy box.
