    [Not just another translator, but a reading-based learning system]
    
    You do not need another translation tool.
    You need a reading system that can turn what you read today into vocabulary you will actually remember later.
    
    Language Annotator is not a traditional flashcard or word list app.
    It works directly inside the pages you already read, so while you are reading news, articles, forums, or documents, you can understand the content and build your own vocabulary library at the same time. Then, through repeated highlighting, saved examples, and review mode, unfamiliar words gradually become familiar ones.
    
    It does not pull you away from reading.
    It turns reading itself into the place where learning happens.
    
    [Why it works]
    
    Most people forget words right after looking them up. The problem is not access to translation. The problem is that lookup and memory are disconnected.
    
    Language Annotator connects them into one continuous flow:
    
    • Translate text directly on the page when you do not understand it
    • Save important words the moment you encounter them
    • Keep examples and useful word information together
    • See saved words highlighted again the next time you read
    • Return later in the word manager or practice mode for real review
    
    This is not a one-time answer.
    It is a personal vocabulary system that becomes more valuable the more you read.
    
    [How you can use it]
    
    Instant translation while reading
    
    Select text on any page to view a translation directly in place, without switching tabs or breaking your reading flow.
    
    Add new words with the right-click menu
    
    When you see a word you want to remember, the process is simple:
    
    → Select the word on the page
    → Right-click
    → Choose Add Word to Annotator Vocabulary
    → Confirm or enter the meaning in the popup
    → Click Save
    
    That way, the word you just truly encountered goes straight into your own vocabulary library instead of being forgotten later.
    
    See saved words appear again in future reading
    
    As you continue browsing foreign-language websites, saved words are automatically highlighted on the page.
    You do not see them only once. You meet them again in new articles and new contexts.
    
    This kind of repeated exposure is more natural, and often more effective, than isolated memorization.
    
    Collect real examples automatically
    
    Language Annotator collects example sentences from the pages you read, keeping the real context in which a word appears.
    You do not only learn what a word means. You also learn how it is actually used.
    
    Return to your word library for review
    
    Beyond on-page learning, you can return to the full word manager to search, edit, and organize saved words, then move into practice mode for deeper review.

    Language Annotator: Your Immersive Reading-Based Learning System
    
    Forget traditional translation tools and fragmented vocabulary memorization. Language Annotator is an innovative reading system that transforms your everyday reading experience into an efficient vocabulary acquisition process, helping you truly remember new words.
    
    Now, Language Annotator fully supports e-book readers, allowing you to seamlessly learn and manage vocabulary while reading e-books in PDF, EPUB, or MOBI formats.
    
    Why Language Annotator Works
    
    Most people forget words immediately after looking them up because lookup and memory are disconnected. Language Annotator uniquely integrates them into one continuous flow, making learning happen naturally within your reading:
    
    Instant Translation & Vocabulary Saving: Select text on any webpage or e-book to translate it directly in place, without switching tabs or breaking your reading flow. Encounter a word you want to remember? Save it instantly, preserving its original context.
    
    Contextual Learning: The system automatically collects example sentences from the pages you read, providing the real context in which a word appears. You don't just learn what a word means; you learn how it's actually used.
    
    Repeated Exposure & Memory Reinforcement: Saved words are automatically highlighted in your future reading. You won't see them only once; you'll encounter them again in new articles and contexts. This natural, repeated exposure is often more effective than isolated memorization.
    Personalized Vocabulary Management: Through the word manager, you can search, edit, and organize all your saved words, then enter practice mode for deeper review.
    
    Language Annotator is not just a translation tool; it's a personal vocabulary system that becomes more valuable the more you read, turning reading itself into the place where learning happens.
    
    How to Use It: Basic Operations
    
    1. Instant Translation While Reading:
    *   Simply select any text on a webpage or within a supported e-book (PDF, EPUB, MOBI).
    *   A translation will appear directly on the page, allowing you to understand the content without interruption.
    
    2. Adding New Words to Your Vocabulary:
    *   When you encounter a word you wish to remember:
    *   Select the word on the page.
    *   Right-click (or long-press on touch devices).
    *   Choose "Add Word to Annotator Vocabulary" from the context menu.
    *   A popup will appear. Confirm or enter the meaning of the word.
    *   Click "Save".
    *   The word, along with its context, is now saved directly into your personal vocabulary library.
    
    3. Seeing Saved Words Highlighted in Future Reading:
    *   As you continue browsing foreign-language websites or reading e-books, any words you've previously saved will be automatically highlighted on the page.
    *   This repeated exposure in new contexts helps reinforce your memory.
    
    4. Collecting Real Examples Automatically:
    *   Language Annotator automatically saves the sentence where you encountered and saved a word, providing you with real-world examples of its usage.
    
    5. Reviewing Your Word Library:
    *   Access the full word manager to search, edit, and organize your saved vocabulary.
    *   Utilize the practice mode for in-depth review and memory consolidation of your collected words.
