Read web pages and PDFs with instant offline etymology highlights and secure on-device Chrome AI word deconstructions. Unlock the hidden structure of the English language while you read. EtymoRead is a lightweight, privacy-first Chrome extension that highlights prefixes, suffixes, and root words on any webpage or PDF document. By combining a comprehensive offline database of 600+ linguistic rules with Chrome's native on-device Gemini Nano AI (window.ai), EtymoRead helps you transition from mechanical memorization to logical understanding. ★ KEY FEATURES 1. Instant Visual Etymology (Hover) Hover over any highlighted word. In 200ms, a premium card slides into view showing the word's prefixes, suffixes, origins (Latin, Greek, Germanic, etc.), definitions, and historical cognate word lists. 2. On-Device AI Deconstruction (Double-Click) Double-click any unfamiliar word to call Gemini Nano. The local model performs context-aware word deconstruction, splitting the word and explaining its meaning relative to the surrounding sentence. 3. Professional PDF Viewer Drag-and-drop local PDFs or intercept web PDF loads. Enjoy CJK (Chinese, Japanese, Korean) glyph rendering, trackpad-safe smooth mouse wheel page transitions, draggable scrollbars, and full keyboard navigation. 4. Smart Anti-Overmatching Filter Our rule-based engine filters out stop words, short pronouns (like "the", "and", "with"), and requires strict affix-to-root coherence. This reduces noise so you only see high-value vocabulary roots. 5. 100% Local Processing & Zero Privacy Risks EtymoRead runs completely offline. Local database checks and Gemini Nano AI queries execute on your personal device's memory. No tracking, no external API calls, and zero data leaves your machine. ★ QUICK START GUIDE FOR LOCAL AI (GEMINI NANO) To use the AI double-click feature, make sure Chrome Local AI is active: 1.
