About

🚀 Turn Your Daily Web Browsing into a Natural Language Learning Habit!

LinguMark is a modern, open-source Chrome extension that helps you learn foreign vocabulary naturally while reading articles, technical documentation, news, or blogs. Instead of opening separate flashcard apps and manually copying words, LinguMark integrates directly into your daily digital reading flow.

Key Features:
• 🔍 Smart Web Röntgen (CEFR Highlights): Instantly scan any webpage to highlight unfamiliar words categorized by CEFR difficulty levels (A2, B1, B2, C1).
• 📚 Oxford Dictionary & Pronunciations: Get accurate definitions, part-of-speech roles, IPA phonetic transcriptions, and authentic audio pronunciation waves (UK/US accents).
• 🔄 In-Place Sentence Translation: Select any sentence and translate it directly on the webpage, maintaining the original page layout and styling.
• 🧠 Spaced Repetition (SM-2): Retain words permanently using the scientific SuperMemo-2 (SM-2) algorithm. LinguMark calculates the optimal review intervals so you review words right when your brain is about to forget them.
• 🔗 Collocation Search: Discover natural word pairings (collocations) and their usage frequency to learn how words are actually used in context.
• 🛣️ FastPath Level Roadmap: Progress through a gamified unit-by-unit map, test yourself with contextual quizzes, and earn XP as you level up.
• ☁️ Cloud Sync & Privacy First: Your data is stored locally in your browser (Offline-First). Sync seamlessly across devices using a secure, serverless backend. We protect your privacy—no tracking, ads, or data selling.

How it works:
1. Browse normally and find an unfamiliar word or sentence.
2. Select the word, right-click, and click "Translate & Save with LinguMark".
3. Practice your vocabulary using the dashboard cards or the FastPath roadmap.

LinguMark is 100% free, open-source, and privacy-respecting.
