Your household's allergen profiles — we call them Mellows — get checked against every single ingredient before you start cooking. Hidden derivatives included. Because "contains milk" should never be a surprise.
🛡️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 that's safe for everyone shouldn't require a spreadsheet — Sentinel checks all profiles at once.
Most recipe sites list ingredients without allergen callouts. Sentinel scans the full ingredient list the moment you open a recipe and flags every risk before you touch a pan.
Sentinel doesn't just match "peanut" to "peanut." It knows the chemical derivatives, alternative names, and hidden sources for each allergen family. Here's what gets caught:
Mellows are individual safety profiles — one for each person in your household. Each Mellow stores that person's allergens, dietary restrictions, and medical constraints. When Sentinel scans a recipe, it checks against every active Mellow simultaneously.
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 safe swap or lets you remove it entirely.
Set up your Mellows in under a minute. Every recipe gets scanned automatically. Available on Chrome, Android, and iOS.
