Paste any recipe URL. MellowMise checks every ingredient against your household's allergies, swaps for any diet, scales the batch, and shows exactly why each change was made — across Chrome, iOS, and Android.


"It's the only tool that handles my kid's nut allergy and my partner's low FODMAP in one recipe — and tells me which ingredients triggered the warning."
"Macros, allergens, and portion scaling — done automatically. I used to spend 20 minutes on a spreadsheet for every meal prep."
"I recommend it to clients. The audit trail shows exactly why an ingredient was flagged — that's something no other consumer app does."
1 cookie or 100. Pinch, tap, or type — every quantity recalculates, even fractions and spoon conversions.
Vegan, gluten-free, low-sugar, nut-free. Smart swaps with confidence scores so you know what survives the oven.
Your household allergen profiles — we call them Mellows — get checked against every ingredient before you start.
I'm the Chef behind it all. I handle the precision, the math, and the allergen and protocol checks, so you can just focus on cooking. I remember your allergies, your scaling preferences, and exactly how your grandmother made it.

We don't just calculate calories. MellowMise is powered by a food science engine designed to balance competing dietary needs with clear warnings.
Advanced allergen derivative expansion (arachis = peanut, gianduja = tree nut). Rule checks flag known derivative terms with word-boundary matching and surface unresolved warnings.
Rule-based warnings for Low Amine, Low Salicylate, Low Glutamate, Diverticulitis, and Low FODMAP-style trigger terms.
When making a substitution, our engine preserves the fundamental cooking chemistry (emulsifiers, leaveners, binders), not just the flavor profile.
