Your household's allergen profiles — we call them Mellows — get checked against recipe ingredients before you start cooking. Known hidden derivatives are flagged for review.
🛡️Casein is dairy. Arachis oil is peanut. Semolina is wheat. Most recipe sites don't flag these — Sentinel does. Our derivative map covers all 9 FDA-recognized major allergens (Big 9, FASTER Act 2023) with 50+ derivative terms.
Dad is gluten-free. Your toddler has a tree nut allergy. Grandma avoids shellfish. Cooking one meal around everyone's constraints shouldn't require a spreadsheet — Sentinel checks all profiles at once.
Most recipe sites list ingredients without allergen callouts. Sentinel checks the full ingredient list and flags known matches before you touch a pan.
Sentinel checks more than exact ingredient names. It uses derivative maps, alternative names, and hidden-source terms for each allergen family. Here are examples:
Mellows are individual dietary profiles — one for each person in your household. Each Mellow stores that person's allergens, dietary restrictions, and medical constraints. When Sentinel checks a recipe, it compares ingredients against every active Mellow.
When two Mellows conflict — say, one person needs high-fiber while another is on a low-FODMAP protocol — Sentinel flags the conflict and suggests ingredient-level compromises rather than forcing you to cook separate meals.
Dairy-free, Low FODMAP, Shellfish allergy
Gluten-free, High protein targets
Peanut allergy, Tree nut allergy, Egg allergy
Diabetic / Low GI, Low sodium
Scrape from a website, open from your Recipe Box, or pick from the Social Pantry.
Hit the shield icon on the recipe detail screen. Sentinel starts scanning immediately.
Every flagged ingredient gets a red alert card showing which Mellow it affects and why.
For each flagged ingredient, Sentinel offers a suggested swap or lets you remove it entirely.
Set up your Mellows in under a minute. Every transformed recipe can show allergen and protocol warnings. Available on Chrome, Android, and iOS.
