## Overview

COSR.AI is a browser-based tool built around a simple question: is the beauty product in your drawer still good to use? Cosmetics carry a batch code (sometimes called a lot number) printed, stamped or embossed on the packaging, and that short string encodes the production run and manufacturing date. COSR.AI lets you pick or search a brand, type in the code, and get back the decoded manufacturing date together with an estimated shelf life and expiration date. It is free, requires no account and works on phones as well as desktops.

The tool leans heavily on education as well as lookup. Its pages walk through where to find batch codes on different packaging types, the common code formats brands use (purely numeric, alphanumeric, date-based, or complex multi-part codes), and how to read the little open-jar symbol that indicates Period After Opening. That symbol — for example '12M' — tells you how long a product stays safe after you first open it, which is often the more urgent limit for creams, mascaras and anything water-based.

Because there is no AI model guessing at your product, COSR.AI's usefulness depends on whether the relevant brand and its decoding logic are supported. It presents itself as a fast, no-friction reference for shoppers buying from discounters, duty-free shops or resellers, and for beauty enthusiasts who want to prioritise which items to finish first based on how much life they have left.

## Pricing & Plans

Completely free to use. No registration, no account and no premium tier are required to decode batch codes; the site also surfaces occasional third-party shopping deals.

## Key Features & Capabilities

- **Brand and batch code lookup:** Select or search among thousands of supported beauty brands, then enter the batch code printed on your product to decode its manufacturing date.
- **Expiry and shelf life estimate:** The tool combines the decoded production date with typical shelf life for that product type to return an estimated expiration date.
- **PAO and cosmetic dating guides:** Explanatory sections cover shelf life versus Period After Opening, common batch code formats and where codes hide on bottles, tubes and outer boxes.
- **No signup, works everywhere:** Results are instant and require no account, and the interface is mobile-optimised for checking products while you shop.
- **Multi-language interface:** The site offers its content in many languages, including English, Spanish, French, German, Portuguese, Japanese, Korean, Chinese and more.

## Primary Use Cases

- **Checking a discount or duty-free purchase (Beauty shopper):** Verify that a serum or foundation bought at a steep discount is old stock by decoding the batch code before you commit to using it.
- **Deciding what to use up first (Skincare enthusiast):** Check the production dates across your shelf and rotate the oldest items to the front of your routine before they degrade.
- **Mascara and eye product safety (Makeup user):** Confirm how long an opened mascara or eyeliner has been in use, since eye products carry the highest contamination risk.
- **Authenticity and freshness checks (Reseller or collector):** Decode codes on items from marketplaces or resellers to spot unusually old stock or packaging that does not match the stated production date.

## Strengths

- Free with no account, signup or paywall in the way
- Clear educational content on shelf life versus PAO
- Covers a wide range of global and niche beauty brands
- Fast, mobile-friendly interface suited to checking products in a store

## Limitations

- Accuracy depends on the brand's decoding rules being in the database
- Expiry dates are estimates based on typical shelf life, not manufacturer guarantees
- No way to report a missing brand or submit a correction from the main flow

## Frequently Asked Questions

### Is COSR.AI really free?
Yes. The batch code checker requires no payment, no registration and no account. You select a brand, enter the code and get an estimated manufacturing and expiry date immediately.

### Where do I find the batch code on my product?
Look on the bottom of containers, the crimped edge of tubes such as mascaras and lip glosses, near the barcode or ingredient list on the box, or etched into glass bottles. It is usually a short string of letters and numbers separate from the barcode.

### What is the difference between shelf life and PAO?
Shelf life how long an unopened, correctly stored product stays stable, typically two to five years. PAO (Period After Opening) is shown by the open-jar symbol with a number of months and tells you how long the product stays safe after you first open it. Whichever limit comes first governs the product.

### Can the tool guarantee my product is safe?
No. COSR.AI returns estimates based on the manufacturing date it decodes and typical shelf life for that product type. Storage conditions, opening and contamination all affect real-world safety, so treat the result as guidance rather than a certification.
