## 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

## Grammarly

Grammarly is the world's most widely deployed AI writing and communication platform, trusted by more than 40 million daily users and 50,000 organizations including Atlassian, Databricks, and Zoom. Operating as a persistent overlay across over 500,000 web applications, desktop programs (Windows and macOS), Microsoft Office, Google Docs, and iOS/Android keyboards, Grammarly analyzes text in real time to eliminate grammatical errors, streamline wordy phrasing, and calibrate tone to match the writer's intent. Following its corporate evolution under the Superhuman Platform umbrella alongside Superhuman Mail and Coda, Grammarly has expanded from a personal proofreader into an enterprise-grade proactive AI communication suite.

In 2026, Grammarly goes well beyond red-underline spellchecking with a suite of specialized AI Agents and document integrity tools. Writers can invoke purpose-built agents—including AI Grader, Citation Finder, Reader Reactions, and Paraphraser—alongside generative AI drafting directly inline where they work. To address academic and professional transparency in the generative AI era, Grammarly offers built-in Plagiarism Detection, an AI Detector, and Grammarly Authorship, which tracks how a document was constructed by automatically categorizing text as human-typed, pasted from external sources, or generated/modified with AI. For teams, Grammarly enforces organizational consistency through custom Style Guides, Brand Tones, reusable Snippets, and Knowledge Share.

Grammarly simplified its subscription structure by consolidating its legacy individual 'Premium' and team 'Business' offerings into a single unified tier: Grammarly Pro. The Free plan ($0/month) covers essential spelling, punctuation, basic tone visibility, and 100 generative AI prompts per month. Grammarly Pro is priced at $12/member/month when billed annually ($144/year) or $30/member/month when billed monthly ($60 quarterly), unlocking unlimited personalized fluency suggestions, full-sentence rewrites, tone adjustment, citation formatting, plagiarism and AI detection, 1 team style guide, and 2,000 generative AI prompts per member each month. Large organizations opt for Grammarly Enterprise (available with Superhuman Go) for unlimited AI prompts, SAML SSO, SCIM provisioning, Data Loss Prevention (DLP), and Bring Your Own Key (BYOK) encryption.

**Pricing & Plans:** Free plan ($0/month) includes core grammar and spelling checks, tone detection, and 100 generative AI prompts/month; Grammarly Pro costs $12/member/month billed annually ($144/year, or $30/month billed monthly) with full-sentence rewrites, plagiarism/AI detection, team style guides, and 2,000 AI prompts/month, while Enterprise offers custom pricing with unlimited AI prompts and BYOK security.

- **Ubiquitous Inline Rewriting & Tone Calibration:** Works natively inside Chrome, Safari, Firefox, Edge, Windows, Mac, Google Docs, MS Office, and mobile keyboards to flag grammar mistakes, rewrite tangled sentences, and shift tone toward confident, empathetic, or executive registers.
- **Specialized AI Agents (AI Grader, Citation Finder & Reader Reactions):** Deploys contextual AI agents that predict how a target audience will react to a draft, locate credible supporting citations, grade essays against rubric criteria, and generate drafts using up to 2,000 monthly prompts on Pro.
- **Grammarly Authorship, AI Detector & Plagiarism Checker:** Scans text against billions of web pages and academic databases for accidental plagiarism, detects AI-generated passages, and logs transparent document provenance via Authorship reports in Google Docs and Word.
- **Team Style Guides, Brand Tones & Knowledge Share:** Enables teams on Pro and Enterprise plans to codify company terminology, ban deprecated jargon, enforce inclusive language, insert shared Snippets, and surface internal company definitions inline.
- **Enterprise Security, DLP & Superhuman Platform Governance:** Protects organizational data with SOC 2 Type 2 attestation, SAML SSO, SCIM lifecycle management, Confidential Mode, Data Loss Prevention controls, Audit Logs API, and customer-managed BYOK encryption.

**Strengths:** Frictionless cross-platform integration works inside virtually every browser, desktop app, email client, and mobile OS without copy-pasting into a separate chatbot.; Consolidating Premium and Business into Grammarly Pro ($12/member/month annual) gives individuals and small teams access to style guides, analytics, and plagiarism/AI detection in one plan.; Grammarly Authorship provides a constructive, transparent audit trail for students and writers to demonstrate human writing integrity alongside responsible AI editing.; Mature enterprise security posture featuring BYOK encryption, Data Loss Prevention, and granular application/domain blocklists.

**Limitations:** Month-to-month billing on Grammarly Pro is steep at $30/member/month compared to the $12/member/month annual commitment ($144 billed upfront).; Core writing intelligence and style rules remain primarily optimized for English dialects (US, UK, Canadian, Australian, Indian) rather than native multilingual grammar checking.; Aggressive inline underlines and pop-up agent cards can feel visually intrusive in dense technical documents or code-heavy web editors unless muted per domain.
