About Free AI Dictionary - Context Explain & Translate
Free AI-powered contextual dictionary for Chrome. Highlight any text on a webpage or PDF and get an instant, context-aware definition in a popup.
Standard dictionaries give you every possible meaning of a word. This extension reads the surrounding paragraph and gives you the one that fits.
What makes it different from a regular dictionary:
- Reads the full paragraph before answering. It knows whether "bank" means a riverbank or a financial institution.
- Translates idioms and technical jargon into your native language with the correct meaning.
- Works on PDFs. Highlight text, right-click, and select "Explain with AI."
- Saves terms and explanations to a personal dashboard you can review later.
- Shows the explanation popup right next to your selected text. No tab switching.
- Lets you ask follow-up questions in a side panel. "What's an example?" or "Explain it simpler."
- Supported languages: English, Spanish, French, German, Portuguese, Italian, Russian, Chinese, Japanese, Korean, Arabic, Hebrew, Hindi, Dutch, Polish, Turkish, Ukrainian, Vietnamese.
Who uses it:
- Students reading dense papers and textbooks.
- Language learners who want to understand meaning, not just get a word swap.
- Professionals going through technical or legal documents.
How to use:
- Webpages: Highlight text, click the icon, read the explanation.
- PDFs: Select text, right-click, choose "Explain with AI."
- Translate: Hit the translate button to see it in your language.
- Save: Bookmark any term to your dashboard.
- Chat: Open the side panel to ask more questions.
