What is Instant Multilingual PDF/HTML/TXT Dictionary

From the Chrome Web Store

Define word(s) on PDF/HTML/TXT pages in just two clicks, even on local docs. Now with ChatGPT support. 🔍 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.
