Find the best thing to buy at the best price
“I'm buying a laptop, TV or appliance and drowning in options.”
AI can narrow options to your real needs, compare the delivered price with coupons, return policies and reviews. It can fill the cart — you check out.
Fix it yourself in 3 steps
- Write what you need it to do, your budget and dealbreakers.
- Ask for the top 3 with a comparison table and delivered price.
- Pick one; let it add to cart if you like, then check out yourself.
Copy this prompt
I'm buying a [item]. Needs: [list]. Budget: [ ]. Dealbreakers: [ ]. Find the top 3 options and make a table: delivered price after working coupons, return window, warranty, key specs, and common complaints from reviews. Link sources. Don't buy or check out — stop after the table.
Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
