Scan any baby food. AllerSee automatically cross-checks every ingredient against your baby's tracked allergen history and the latest FDA recall feed - in seconds, before you open the pouch.
AllerSee is Baby Ledger AI's allergen safety layer. It runs automatically on every barcode scan and every AI photo scan, on every subscription tier, free of charge and without scan limits. The system reconciles four independent data sources to produce a single per-baby advisory the parent sees before logging the food.
For packaged products, AllerSee reads the UPC/EAN barcode and resolves the product against a 3+ million-item ingredient database (Open Food Facts plus internal augmentation for U.S. baby-food SKUs). For homemade or unpackaged food, AllerSee uses a vision model to identify the dish and infer its likely ingredient list.
AllerSee's product database draws from Open Food Facts, which covers imported baby foods from 200+ countries with allergen tags normalized to a single English vocabulary. The cross-check against your baby's tracked allergen ledger works the same whether the package label is in English, Japanese, Chinese, Korean, German, or Cyrillic - because the allergen reconciliation runs against the normalized tag, not the on-package text. For barcode scans of products in our database, the language printed on the package doesn't affect detection. For products not yet in the database (homemade food, unpackaged items, very new SKUs), AllerSee's AI vision can read non-Latin labels, though we recommend barcode scanning whenever available for highest reliability.
The system reconciles the identified ingredients against the active baby's parent-entered allergen ledger. Each ledger entry carries a parent-recorded severity level and a date of last exposure. Households with multiple children maintain a separate ledger per child.
When a high-severity match is detected, AllerSee surfaces a blocking modal that prevents auto-logging and displays a hard-block alert reading "DO NOT FEED" for that baby. Lower-severity matches surface a non-blocking advisory. In all cases the parent retains a "View Details Anyway" path so the advisory is informational and never overrides parental judgment.
In parallel with the allergen check, every barcode scan is cross-checked against the active U.S. FDA and USDA food-recall feeds, refreshed daily. Class I recalls (FDA's most-serious classification) are flagged with a distinct red advisory. Recall data lags official FDA and USDA publication and should not be relied on as a sole source for time-critical recall awareness.
Allergen ledger entries and confirmed reactions sync across all caregivers (partner, nanny, grandparents) attached to the baby's profile in real time. A reaction logged by the partner at the pediatrician's office is reflected the next time the other caregiver opens the scanner, before the next feed.
Most allergen apps work in English only. Travel home with a Japanese baby food jar, a Korean rice puff, or a Chinese tofu pouch and they often fail silently. AllerSee was built for the parents who don't only shop the U.S. supermarket aisle. Label-reading (OCR) is strongest for English, Japanese, Chinese, and Korean. For packaged products in our database, allergen detection works regardless of label language because the cross-check runs against normalized ingredient tags. Detection depends on product-database coverage and accurate label parsing; always verify the package label.
AllerSee resolves products from a 3+ million-item database. Most well-known U.S. baby food brands are included out of the box, alongside international and store-brand products parents buy in real life.
AllerSee is included on every Baby Ledger AI plan, including Free, with no scan limits. No credit card. No trial countdown.
