Häufig gestellte Fragen
Is the scaling done by AI?
No. Quantities are scaled with straightforward math, parsing the number and unit from each line and multiplying by the ratio between your original and desired servings, no AI guessing involved.
What ingredient formats are supported?
Whole numbers, decimals, simple fractions (1/2) and mixed numbers (1 1/2), with or without units like cups, tbsp, tsp, oz, g or ml, for example "2 cups flour" or "3 eggs". Lines it can't parse a quantity from are shown unchanged with a note.
How are the substitution suggestions chosen?
From a fixed, curated list of common baking and cooking swaps (egg, butter, buttermilk and more), matched by keyword against your ingredient names, not generated by AI. Always sanity-check a swap against your specific recipe.
