  📘 **DD Vocab: Learn English words effortlessly — one click, smart drills, real context.**
  
  DD Vocab is a simple browser helper for anyone learning English. Highlight a word while you read or watch in Chrome or Edge. In one click, you see the meaning, pronunciation, and example sentence — and the word is saved for easy review later. No login, no sign-up. Just highlight English words and learn.
  
  **⚡ Your first 30 seconds**
  1. Highlight any English word on any page
  2. A small popup shows: meaning, IPA, pronunciation audio, and the sentence you found it in
  3. Click "Save" and the word goes to your list — no account, no setup
  
  That's it. Everything else is optional.
  
  **✨ Clean Lookup on Chrome, Edge, and YouTube**
  Works in Google Chrome and Microsoft Edge. Use it on articles, web apps, Google Docs, and YouTube videos (with captions) to catch new English words as you go.
  
  **📝 My Words — Your Saved English Vocabulary**
  Inside the popup, the My Words tab holds every word you've saved:
  • Shows the first 20 words, with "show more" so the list never feels overwhelming
  • Search, see IPA, play audio, read the original context sentence, and check the definition
  • Difficulty/frequency tags (e.g. Moderate / Advanced / Academy) in the list and drills
  
  **💪 Practice — Smart, Automatic, Brain-Friendly Review**
  The Practice tab turns your word list into learning:
  • **Smart spaced repetition** — DD Vocab chooses which words to show today, spacing reviews so they come back just before you'd forget. You remember more with less effort.
  • **5 drill types** — listen & choose, cloze fill (fill the blank), definition matching, hint recall, and sentence listening. Not just flashcards.
  • **AI Drills (optional)** — with a connected DeltaDaily account (or optionally your own Gemini API key), DD Vocab creates richer exercises from your own sentences: fill-in-the-blank, mini quizzes, and other context-based drills.
  
  **🎬 YouTube Caption Word Capture**
  Learn vocabulary while watching YouTube videos. When captions are on, every word becomes clickable — single-click any word to save it instantly. No pausing, no copy-pasting, no interruption. The video keeps playing while your word is saved in the background with the full caption sentence as context. Review later in your word list with a direct link back to the exact moment in the video.
  
  **🔊 Pronunciation on Every Word**
  Hear any word spoken aloud, both in the tooltip and in your word list. Build listening skills alongside vocabulary.
  
  **🔤 Optional Difficulty-Based Highlighting**
  DD Vocab knows English word frequency and difficulty, and lets you set your target level (e.g. Moderate, Advanced, Academy):
  • Turn on "Highlight target words on the page" to see good vocabulary candidates as you read
  • Off by default — nothing on the page changes unless you want it
  
  **🌐 Translation from English into Your Language**
  DD Vocab is for English learners — the source language is always English. With a connected DeltaDaily account, you can:
  • Choose your preferred target language (e.g. Chinese, Japanese, Spanish)
  • Get one-click translation of definitions or example sentences into your language, right inside the popup or drills
  • Stay in English most of the time, and use translation only when you need extra clarity
  
  **🎓 Ready on Install — No Sign-Up Required**
  Start immediately with 20 curated starter words across everyday, academic, professional, and current-events categories. No account, no email, no setup.
  
  **📤 Export & Integrations: Anki, Quizlet, DeltaDaily**
  • Import your existing English word lists (from text/CSV)
  • Export from DD Vocab in ready-to-import formats for Anki and Quizlet
  • Connect DeltaDaily to sync your vocabulary across devices and power deeper, structured English training — without manual copy-paste
  
  **Who is this extension for?**
  • ESL learners who are tired of abandoned word lists on Google Docs
  • Anyone who wants their word list **synced across devices** without manual export/import
  • Learners who want **translations** alongside definitions and IPA
  • Anyone who wants **AI drills without managing their own API key**
  • Serious college and graduate students reading English research papers
  • Professionals who want a complete English learning toolkit beyond just a dictionary

  DD Vocab is a browser extension — it works inside Chrome and Edge browser tabs. Chrome's built-in PDF viewer uses a separate plugin that doesn't support extensions.
  
  💡 **Tip for PDF readers**: Open PDFs in a web-based viewer like Google Docs or Mozilla PDF.js — then all DD Vocab features work because the PDF renders as normal HTML.
