## COSR.AI Cosmetic Batch Code Checker

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.

- **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.

**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

## Dechecker

Dechecker centers on a paste-and-check workflow: you drop in up to roughly 1,000 words, or upload a document, and the detector returns an overall AI probability plus a sentence-level breakdown showing which passages triggered the model. Alongside the core check you can stack optional passes such as a plagiarism scan, a grammar pass and a fact-check, and the platform also exposes sibling tools for AI code detection, AI image detection, transcription, summarization and essay writing.

Its stated positioning is accuracy with few false positives, achieved by scoring sentence structure, phrasing rhythm and transitions rather than looking for fixed keyword lists. When something is flagged, the tool explains why that sentence reads as machine-generated and offers one-click rewriting so writers can smooth the pattern out instead of rewriting from scratch. Bulk document upload, downloadable reports and a saved history are provided for people checking more than one file.

Accessibility is the main selling point: the checker is free, needs no account for a basic run, and shows a "100 free credits" offer alongside paid options for heavier usage. Text is described as processed without being stored, which matters for students and professionals checking unpublished coursework or client material. The site is translated into several languages and claims more than a million users.

**Pricing & Plans:** Dechecker advertises a free tier with no registration required for basic AI checks, and the site surfaces a "claim your 100 credits" offer for signed-in users. Beyond that, plan details and paid tiers vary, so check the pricing page for current limits and per-word or per-credit bundles.

- **Sentence-level AI detection:** The checker returns an overall AI probability plus a per-sentence breakdown, so you can see exactly which lines read as machine-written instead of guessing from a single number.
- **Built-in humanizing rewrites:** Flagged sentences come with an explanation of what triggered the flag and one-click rewrite suggestions that reduce tell-tale AI patterns while keeping your meaning.
- **Add-on verification passes:** Optional plagiarism, grammar and fact-check modules can be layered onto the same text, turning a single submission into a broader originality and quality review.
- **Document upload and bulk scanning:** Paste text directly or upload files, and scan multiple documents in one pass when you are reviewing a stack of papers or drafts.
- **Report history and downloads:** Detection results are saved to a library and can be exported, which helps when you need a record of checks over time or proof of a review.
- **Extra detectors for code and images:** Separate tools detect AI-written code and AI-generated images, covering project types beyond plain essays and articles.

**Strengths:** Core AI check is free and requires no signup for a quick run; Sentence-level explanations make results actionable rather than just a score; Extra plagiarism, grammar and fact-check modules cover more ground in one place; Document upload, bulk scanning and saved reports suit multi-file workflows

**Limitations:** The free allowance is credit and word limited, so heavy use runs into paid tiers; AI detectors in general can still misfire on heavily edited or non-native human writing; Detection accuracy depends on language and text length, so very short passages are less reliable
