Scan the menu.
See what to avoid, and why.
AllerLens reads a restaurant menu page by page and checks every dish against the allergies you set.
Guidance, not medical advice. Always confirm ingredients with restaurant staff before you order.
What the app does
Scan every page of the menu
Photograph each page, sauces and sides included. A dish that points to a page you didn't scan gets Ask staff, not a guess.
Screen: Corner Diner in the app: Ice Cream marked Ask staff, Fruit Plate Safe, Peanut Satay Avoid, Honey Mustard and Ranch Safe, Sesame Ginger Avoid.See what to avoid, and why
Tap a dish to see which of your allergens it likely contains, and every reason, down to a shared fryer.
Screen: Chicken Tenders marked Avoid: contains peanuts and sesame, followed by the list of reasons.Not sure? It tells you to ask
When the menu gives no ingredients, AllerLens says so. Ask staff is not the same as safe, and the app doesn't pretend it is.
Screen: Scallion Pancake marked Ask staff: the menu gives no ingredients, so sesame could not be ruled out.Read menus in other languages

Your allergies stay on your phone
To read a menu, the photo goes to our server, which passes it or its text to Anthropic (Claude) and Google Cloud Vision. Your allergy list never leaves the phone, and the photo isn't kept.
- Your allergies
- On your phone. Matching against the menu happens on the device too.
- Scans and saved dishes
- On your phone.
- Menu photos
- Sent over HTTPS to read the menu, then discarded. Never stored.
- Location
- Optional. Used to find the city, postal code and country. Never sent to AllerLens.
- Account
- There isn't one. Nothing to sign up for or sign in to.
- Problem reports
- Only if you send one: the dish, its tag, the reason you picked and the app version. Nothing that identifies you.
