Your resized recipe
Amounts update instantly.
Quantities are mathematical estimates. A grown-up should check cooking times, temperatures, allergies and whether the scaled result makes sense for the recipe.
Build the recipe tool your family needs
AI can turn one of your own repeated kitchen calculations into a simple private app—without another account or subscription.
Build me a polished, mobile-friendly recipe resizer as one standalone HTML file. Let me name a recipe, enter its original number of servings and add editable ingredients with amount, unit and name. Let me choose a new serving count and instantly scale every amount, tick ingredients while cooking, print the result and save the recipe locally. Format decimals sensibly, include an editable starter recipe, accessible controls, an accurate privacy note and a clear reminder that a grown-up must check food safety, allergies and cooking instructions.
Privacy: The recipe and chosen serving count stay in this browser’s local storage. The app has no account, analytics, advertising or external service. Clearing browser data removes the saved recipe.
Grown-up note: This tool only multiplies quantities. It cannot judge food safety, allergies, cooking temperature, timings or whether every recipe scales perfectly.
