The allergy chef card you hand to restaurant staff — in their language
A chef card is the classic, trusted way to communicate food allergies abroad: a short written note you show the kitchen so nothing gets lost in translation. TrustBite builds yours automatically in 24 languages — including Thai, Japanese, Chinese and Arabic — and it works fully offline, so you're covered even with no signal. Add a barcode scanner, AI menu scan and an ICE emergency contact, all free.
What a chef card is — and why it works abroad
A chef card (sometimes called an allergy translation card or restaurant card) is a concise written statement of what you cannot eat, handed directly to the kitchen. Spoken requests get misheard, softened by a well-meaning waiter, or lost across a language barrier; a card in the staff's own language reaches the chef exactly as you meant it. TrustBite generates your card from your saved allergen profile, naming each allergen clearly and marking how serious your reaction is, so busy kitchens can act on it in seconds rather than guessing.
24 languages, all 14 EU allergens, marked by severity
Your card is available in 24 languages, including non-Latin scripts many phrasebooks skip — Thai, Japanese, Chinese and Arabic — alongside German, French, Spanish, Italian, Turkish, Polish, Greek, Vietnamese and more. It covers all 14 EU-recognised allergens: gluten, peanut, tree nut, milk, egg, fish, shellfish, soy, sesame, mustard, celery, sulphites, lupin and mollusc. Each one is shown with its severity, so staff can tell the difference between a mild intolerance and a strict, life-threatening avoidance and treat it accordingly.
Offline card, scanner, AI menu scan and an ICE contact
Everything you need at the table lives in one free app. The chef card works fully offline — no roaming, no Wi-Fi needed — so it's ready in a remote village or on a plane. Scan a product barcode for an instant green, yellow or red read from the Open Food Facts database, or point the AI menu scan at a foreign-language menu to see which dishes may be risky. You can also store an ICE (in case of emergency) contact right on your profile, so help is a tap away if something goes wrong. TrustBite is free, with an optional Pro upgrade.
FAQ
What exactly is a chef card?
A chef card is a short written note you hand to restaurant kitchen staff listing the foods you must avoid, in their own language.

TrustBite creates yours automatically from your allergen profile in any of 24 languages.
Does the allergy card work without internet?
Yes. Your chef card is stored on your device and displays fully offline in all 24 languages, so you can show it with no signal, no Wi-Fi and no roaming — ideal for remote destinations, flights or areas with poor coverage.
Which languages and allergens are covered?
The card is available in 24 languages, including Thai, Japanese, Chinese and Arabic, and covers all 14 EU-recognised allergens — gluten, peanut, tree nut, milk, egg, fish, shellfish, soy, sesame, mustard, celery, sulphites, lupin and mollusc — each marked with how severe your reaction is.
Is TrustBite a medical device?
No. TrustBite is a communication and information aid to help you share your allergies and research food while travelling — it is not a medical device and does not diagnose, treat or guarantee safety. Always confirm details with restaurant staff, and in a severe reaction call your local emergency number (112 in the EU).
