About Instant Multilingual PDF/HTML/TXT Dictionary

🔍 Enhance your reading experience with our extension. Easily obtain definitions by selecting a word or phrase. Click the floating icon, use the Alt+Shift+Z shortcut, or right-click to choose 'Define [your selected word(s)]'. 🆕 Now with robust PDF support: If tooltips cannot be shown in PDFs, the extension automatically opens a popup window for definitions, ensuring a seamless experience even in Chrome's built-in PDF viewer. 🔑 Key Options: - 🎛️ Customize Shortcuts: Tailor a shortcut that complements your workflow. - 📚 Definition Providers: Choose your primary definition provider. We now feature the versatile ChatGPT, supporting languages including Arabic, Brazilian Portuguese, Bulgarian, Chinese (Simplified), Chinese (Traditional), Czech, Danish, Dutch, English (UK/US), Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Romanian, Russian, Slovak, Spanish, Swedish, Thai, Turkish, Ukrainian, and Vietnamese. - 🖼️ Popup Window Configuration: Personalize the popup window's appearance and functionality. - 🔗 Web Search Link: Easily access extended information with a 'Search the web' link. - 💡 ChatGPT Backup: Utilize ChatGPT as an additional source for definitions (register at chatgpt.com if required). 🌟 Special Feature: Enable word pronunciation on Content Security Policy (CSP) protected pages like github.com with our 'CSP Page Pronunciation' option. This feature is initially disabled 🔒 and can be activated based on site policies. ⚠️ Note: Our extension is compatible with native PDF formats (including Chrome's built-in PDF viewer) and now automatically falls back to a popup window if tooltips cannot be displayed. Protected or scanned documents are not supported. For local document access, enable the 'Allow access to file URLs' option on the chrome://extensions page. 📃 Changelog Highlights: -- 📜 Version 2.4.0: Added Search History functionality to easily view and retrieve your past definitions. -- 🎯 Version 2.3.0: Added Selection Icon for instant translation, increased popup font size for better readability, and improved overall reliability. -- 🪟 Version 2.2.146: Enhanced popup window system with keyboard shortcut support for recursive lookups within definitions, resizable fallback windows with position memory across sessions, and improved reliability with context menu duplicate error fix. -- 🔧 Version 2.1.142: Enhanced code quality and user support experience. Fixed tooltip reuse logic to prevent stale "thinking..." text, improved tooltip visibility on complex pages, added direct support hub link in Options for faster issue resolution, and modernized keyboard event handling. -- 🚀 Version 2.0.140: Major update! PDF support is now robust—when tooltips cannot be rendered (e.g., in Chrome's PDF viewer), the extension automatically opens a popup window for definitions. Popup window creation and positioning have been overhauled for reliability and user experience.
