Highlight New Words – Vocabulary Builder for Youdao, Eudic, CET & IELTS

Highlight New Words is a vocabulary builder and word highlighter for English learning: it marks the words you are studying on any web page and in YouTube captions, taken from your Youdao or Eudic word book or from the built-in graded word lists. Hover (or tap on mobile) to see phonetics, meaning and word forms, and mark a word as known in one click so it never shows up again. Note: the interface and the built-in glosses are in Simplified Chinese. CHOOSE WHAT TO LEARN - Built-in graded word books covering Chinese school, university and graduate entrance exams and common study-abroad tests, plus CEFR levels and COCA frequency bands. Combine them freely; pick B2 to highlight B2 and above. - Sync your cloud word books from Youdao Dictionary and Eudic. Each remote word book becomes a separate book with its own sync status; Eudic's "mastered words" list can be synced as a known-words list. - Import your own lists from plain-text or spreadsheet files, or from word lists exported by Youdao, Eudic or Anki. READ WITHOUT INTERRUPTION - Inline glosses after or above each highlighted word, switchable at any time. - Word card with phonetics, pronunciation, full definitions, exam tags and word-form notes such as "past tense of run". - Choose how the card opens: hover (adjustable delay), hold a modifier key while hovering, or click; tap on touch screens. - Lemmatization: running and ran both count as run; marking a word as known hides all of its forms. - Many highlight style presets (or show glosses only, without highlighting), per-book colors, automatic contrast on dark pages. - Code block highlighting (off by default): mark new words in code comments and strings on technical pages; online editors and input fields are left alone. YOUTUBE CAPTIONS - New words in captions are highlighted, with short glosses above, below or after the word. - Press Alt+L to pause the video and open the current-caption panel: the sentence is shown large, every word can be looked up, and you can step to the previous or next sentence or resume playback from there. - Optional: pause automatically while the mouse is over the captions and resume when it leaves. MOBILE AND TOUCH - Works on mobile browsers such as Microsoft Edge for Android, with a touch-friendly bottom card. - A floating button at the screen edge lists the new words on the page (mark them as known in one tap) and offers a word-pick mode (tap any word to look it up), quick settings (inline glosses, word books) and sync status. On YouTube video pages it opens the current-caption panel directly. Drag it anywhere or hide it per site. WORD BOOKS, KNOWN WORDS AND SYNC - "Add to word book" on the card saves a word to a local word book or to your Youdao / Eudic cloud word book. - When marking a word as known, choose which known-words lists to write to and which word books (local or cloud) to remove it from; by default it only goes to the local known-words list. Undo is available for 10 minutes. - Import and export your known-words list. - Settings, known words and imported books can be synced or backed up in several ways, used together if you like: your browser account; WebDAV on a server you own; or a manual backup file, imported with merge or overwrite. Credentials such as the Eudic token or WebDAV password are not uploaded unless you opt in. MORE - Turn highlighting on or off per site; the toolbar badge shows how many new words are on the page, and the popup lists them along with sync status. - Page text is matched locally and never uploaded. The extension has no developer server and no analytics. Usage And Feedback: https://github.com/xqdd/highlight-new-words/issues
