Fill your grocery cart with AI

“I know what I need; I just don't want to click through the grocery app.”

Give AI your list (even a photo of a handwritten one) and it can fill an online cart, picking sizes and swaps by your rules. You review and check out.

Fix it yourself in 3 steps

Write or photograph your list, and say your store and brand or size preferences.
Ask the AI to fill the cart and list anything it substituted or couldn't find.
Review the cart, then check out and pay yourself.

Copy this prompt

Fill my [store] cart with this list: [list or photo]. Prefer [brands/organic/store brand], cheapest size per unit unless I say otherwise. List every substitution and anything not found. Stop at the cart — don't check out, choose delivery slots or pay.

Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
