Know what’s in it before you eat it
Scan a barcode or photograph the ingredient label. PNut reads it — in 40+ languages — and tells you whether your allergens are in there.
Download on the App StoreSee how it works
No account. Nothing to type. Works on labels in languages you don’t read.
Two ways to scan
Whichever the packet gives you
Scan the barcode
Point the camera at the barcode. PNut looks the product up in the Open Food Facts database of millions of products and checks the ingredient list against your allergens.
Photograph the label
No barcode, or an imported packet in another language? Take a photo of the ingredients and PNut reads and analyses them in 40+ languages.
What a result looks like
The verdict, the reasoning, and the ingredients it read
Every scan shows why it decided what it decided, and the ingredient text it worked from, so you can check its work against the packet in your hand.
Four possible answers
Plain verdicts, including “I don’t know”
Every scan lands on one of four results, each with the reasoning and the ingredients PNut read.
- Safe
None of your allergens appear in the ingredients.
- Contains allergen
An allergen you selected is listed in the ingredients.
- May contain
The label warns of traces or shared equipment.
- Unknown
The label could not be read or the ingredients are incomplete.
Why it helps
Made for reading labels under pressure
40+ languages
Labels in Spanish, French, Arabic, Chinese, Hindi, Turkish and more — read and explained in your language.
Your allergen list
Pick the allergens that matter to you. PNut only flags what you asked about.
Built for travel
Imported and local packets alike. Useful exactly where the label is unreadable to you.
Results in seconds
Scan, wait a moment, get a verdict with the reasoning and the ingredients it extracted.
Says when it is unsure
A blurred or partial label returns Unknown rather than a guess.
No account needed
Open it and scan. Your allergen preferences stay on your device.
Allergen guides
Learn the names that hide on labels
Casein is milk. Semolina is wheat. Each guide lists the aliases, the label wording by region, and what “may contain” really means.

Questions people ask
- Does PNut work on labels in other languages?
- Yes — it reads ingredient labels in over 40 languages and explains the result in yours. That is the case it was built for: an imported packet you cannot read.
- What does “May contain” mean?
- The label itself warns about traces or shared equipment — for example “may contain traces of nuts”. The allergen is not an ingredient, but the manufacturer will not rule it out.
- Can I trust the result?
- Treat it as a fast second pair of eyes on the label, not a guarantee. Labels change, lines are shared, and a photo can miss text. If a reaction could be severe, confirm with the manufacturer.
- Which allergens does it detect?
- Peanuts, tree nuts, milk, eggs, wheat and gluten, soy, fish, shellfish and sesame, plus others you add to your list.
- Does it need an internet connection?
- Yes. Barcode lookups and label analysis both happen over the network.
- Is it free?
- There are free scans every week. Unlimited scanning is a subscription.
