Product Label Scanner

The Product Label Scanner uses advanced client-side Optical Character Recognition (OCR) powered by Tesseract.js. When you upload a photo or snap a picture of an ingredient list, the tool extracts the text locally in your browser. It then cross-references this text with a curated database of common food and cosmetic additives and allergens to give you an instant safety and allergen analysis.

No. This tool is built with a strict privacy-first architecture. All image processing, text recognition (OCR), and ingredient analysis happen locally inside your web browser. No photos, parsed text, or personal data are ever sent to external servers or databases, making the tool 100% secure and private.

To scan a product on mobile, simply tap the 'Scan with Camera' button. On HTTPS production sites, this will open a live video viewfinder directly in your browser. Alternatively, you can tap 'Take Photo' to open your phone's native camera app, snap a clear picture of the ingredient list, and load it into the scanner. Both methods process the image client-side.

E-numbers are systematic codes used in Europe and internationally to identify food additives that have been cleared for use. Yes, the scanner automatically cross-references E-numbers (such as E250 for Sodium Nitrite or E951 for Aspartame) against its database, translating them into plain English and highlighting their purpose and safety level.

Yes. The scanner database is equipped to analyze both food additives and common cosmetic chemicals, including parabens, sulfates (like SLS and SLES), silicones, phthalates, synthetic fragrances, and chemical sunscreen filters (like oxybenzone), providing safety ratings and irritation warnings for skin health.

OCR accuracy depends highly on the quality of the photo. For the best results, ensure the ingredient text is flat, well-lit, in sharp focus, and free from glare or shadows. Highly curved packaging can sometimes distort letters, but you can edit the raw recognized text inside our interactive editor before running the analysis.

Safety ratings are calculated based on scientific consensus and safety directives: Green (Safe) indicates natural or highly cleared ingredients with no known health risks; Yellow (Moderate) indicates potential mild irritants, sweeteners, or additives with usage limits; Red (Danger) indicates additives with high links to health controversies, toxicity, or carcinogenicity.

Yes. You can toggle allergen alert switches in the dashboard control panel. The scanner supports filtering for Gluten, Dairy/Lactose, Soy, Peanuts/Tree Nuts, Eggs, Shellfish, and Sesame. If any keywords related to these allergens are detected in the ingredient label, a highlighted warning banner will immediately notify you.

When you scan a product, you can click 'Save to Compare' to store its safety scorecard in your browser's local memory. You can then scan a second product, click compare, and view a side-by-side dashboard comparing their ingredient count, flagged hazardous additives, matching allergens, and total safety rating.

No. The Product Label Scanner is an educational tool designed to help you decode ingredient lists and understand common additives. It is not a medical device and should not replace professional medical advice, diagnosis, or treatment for severe food allergies or medical conditions.
