Barcode apps depend on someone else’s database
- Products can be missing, imported, local, or newly packaged.
- Old product records can differ from the package in your hand.
- A barcode match may not explain allergen or “may contain” wording.

AI reads the visible text, then deterministic rules check supported gluten-related terms and warnings.
See detected gluten evidence, a visible product-level gluten-free claim, or why the result remains unknown.
Reading each label is tiring, and gluten isn't always obvious. GlutenScan can help.
Scan the package in front of you and easily review ingredients, allergens, and advisory statements.
Wheat and barley are obvious. Malt, brewer's yeast, soy sauce, and others are not.
Gluten can show up outside the grocery shelf too, including products like toothpaste, so ingredient labels still deserve a quick scan.
GlutenScan reads the actual label, so it can help with imports, local brands, bakery items, and deli products when there is no reliable barcode result.
Hi, I'm Coralie. Growing up in France, bread was a staple at every meal. When I met my partner, my eyes were opened to a different reality — one where we're reading every ingredient label, worrying about stomach pain, bloating, and exhaustion (at the very least) if we get it wrong, and asking restaurant staff whether a dish can be made safely for someone with celiac.
GlutenScan uses AI to read visible ingredient and allergen text from a label, then flags declared gluten sources and terms that may need a closer look.
GlutenScan currently applies its validated U.S. FDA rulebook to English-language packaged-food labels. Unsupported or unclear label languages return unknown rather than safe. Some meat, poultry, egg products, and alcoholic beverages are regulated by USDA or TTB rather than FDA, so always verify the current package.
Instead of manually decoding every ingredient in a long list, you can scan the label and review the terms GlutenScan flagged. It helps focus your attention when you are comparing products, tired, or unsure whether a label term is gluten-related.
Yes. Scan history is included for free signed-in users. The $15 USD per year paid plan unlocks favorites, so you can keep important label checks easy to find.
GlutenScan can surface visible statements such as “may contain,” “shared facility,” or “shared equipment” when they appear on the label. It cannot detect undisclosed cross-contact or manufacturing conditions that are not printed on the package.
GlutenScan reads the visible label text rather than relying only on a barcode database. That can help with imports, local brands, bakery labels, deli labels, and private-label products when the ingredient list is readable.
Safe requires a complete, readable, supported label with a finished-product gluten-free claim and no contradictory evidence. Unsafe means the visible label contains gluten evidence or a relevant precautionary warning. Unknown means GlutenScan cannot establish safety. No result certifies a product or replaces professional advice.
No. GlutenScan reviews visible label text only. It cannot test food, verify factory controls, diagnose celiac disease, or guarantee no cross-contact.
GlutenScan is designed to be transparent about uploads, processing, scan history, and deletion controls. See our Privacy Policy for current details.
