How It Works: - For a single word: Double-click to get dictionary definitions (Cambridge, Merriam-Webster, Gemini). - For a short phrase (2-5 words): Select and double-click for an AI-powered meaning. - For a longer sentence: Select and double-click to translate it into your chosen language. - Hear it aloud: Use the text-to-speech (TTS) button for any word, phrase, or sentence. - Right-click option: Alternatively, right-click any selected text and choose the "Look up" option. Key Features: - Instant popup with parts of speech, examples, pronunciations, and audio (when available from Cambridge Dictionary). - Phrase support (2–5 words) and sentence translation using AI. - Text-to-speech playback with fallback for single-word audio. - Saved Words manager with search, filters, multi-select, and bulk delete. - Export vocabulary in CSV or JSON formats. - Enable or disable DefineX per site from the toolbar popup. - Customizable sources (Cambridge, Merriam-Webster, Gemini), definition scope, example count, target language. Notes: - Phrase meanings require the Gemini source. - Some sites (e.g., Chrome Web Store pages, PDFs, and ChatGPT) may restrict in-page overlays, causing features to break or be unavailable.
