Safety Sentinel

Allergens, caught early.

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.

🛡️
Why families need this

Allergens hide in
plain sight.

🥜

Hidden derivatives

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.

👨‍👩‍👧‍👦

Multi-person households

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.

📋

Recipe sites don't warn you

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.

Deep allergen intelligence

Beyond the label.

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:

One kitchen, many mouths

A Mellow for
everyone at the table.

Family profiles that travel with your recipes.

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.

Mellows sync across devices. Set them up on your phone and they're active in the Chrome extension, and vice versa. Your family's safety profile is always current.
