Smart dictionary for specialized and foreign language documents. Click any text for context-aware translations and explanations. Professional Reader — Smart Dictionary for PDFs & Web Pages Stop switching between your document and a dictionary. Professional Reader lets you click on any text in PDFs or web pages to instantly see context-aware translations and explanations — right where you're reading. Built for researchers, students, and professionals who work with specialized or foreign language documents. HOW IT WORKS 1. Browse any webpage or open a PDF 2. Click, drag, or Shift+click to select text you want to understand 3. A tooltip appears with a translation or explanation — powered by AI that reads the surrounding context 4. Want to dig deeper? Open "Detail Search" to ask follow-up questions in a multi-turn chat That's it. No copying, no tab-switching, no interruption to your reading flow. SUPPORTED LANGUAGES Professional Reader supports 5 languages for both the interface and translations: - English - 日本語 (Japanese) - 中文 (Chinese Simplified) - 한국어 (Korean) - Español (Spanish) The AI automatically detects the language of your selected text and provides translations or explanations accordingly. CONTEXT-AWARE INTELLIGENCE This is not a simple dictionary lookup. When you select text, Professional Reader analyzes the surrounding sentence to understand how that word or phrase is being used. The same term can mean very different things depending on context — and Professional Reader gets it right. DESIGNED AROUND YOUR READING FLOW Professional Reader is built to stay out of your way. You can toggle the extension or hover highlighting on and off without leaving the page, and the settings panel can be freely repositioned to wherever suits you. The tooltip itself is resizable. Press Ctrl/Cmd+C while the tooltip is open to copy the selected text and dismiss the tooltip in one shortcut. The amount of context the AI considers is also adjustable, so you can tune it to match the material you're reading, and all your reader settings persist across reloads. Whether you click, drag, or Shift+click to select text, everything is designed to keep your reading flow uninterrupted.
