The only scientific kitchen assistant that syncs seamlessly from your browser to your kitchen counter. Scale servings. Swap ingredients for any diet. Flag allergens before they hit the counter.


"It's the only tool that handles my kid's nut allergy and my partner's low FODMAP in one recipe."
"Macros, allergens, and appliance tweaks—done automatically. Zero spreadsheeting."
"Feels friendly because of Romellow, but the outputs are clinical-grade strict."
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 safety checks instantly, 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 clinical-grade food science engine designed to balance competing dietary needs safely.
Advanced allergen derivative expansion (arachis = peanut, gianduja = tree nut). Failsafe auto-correction loops ensure outputs are ruthlessly checked against word-boundary regex.
Built-in support for Low Amine, Low Salicylate, Low Glutamate, Diverticulitis, and Monash University standard Low FODMAP.
When making a substitution, our engine preserves the fundamental cooking chemistry (emulsifiers, leaveners, binders), not just the flavor profile.
