Household Grocery List

Status: Live.

1. Your muse

   A shared grocery list for one household. Anyone with the link can add an item and tick it as bought. Items must be saved on the server, so they are still there after a reload and in a different browser. Keep it to one list. Made-up test data only.

    Limits

    • Anyone with the link can add, tick, edit or remove any item.
    • No sign in, so the product cannot tell who added what.
    • List shows saved server data on load. New changes need a refresh if open in two browsers at once.
    • Test data only. Do not enter real personal details.

    From your inspo

    The person gave text only asking for a shared household grocery list with link access that persists across reloads.

    Takes

    • One shared list for a household
    • Add an item and tick it as bought

    Cost per run: about $0.004 (est.). One Wonder call to tidy one item name uses about 300 input tokens ($0.0012) plus about 100 output tokens including reasoning ($0.002). Data saves are free. Total about $0.0032, rounded to $0.004 per run.
