Instant definitions, translations, and search results for words and phrases you select or type
Search the web without opening a new tab at the instant you select text on a page. Fetch definitions, translations, and examples from multiple sources in multiple languages at the same time. View results in a small pop-up bubble next to the selection area. Or search from extension's popup window by typing the query, instead of selecting it on a page.
Customizability is a priority, so in options app you can configure:
⚙️ Bubble activation
Configure how and when to trigger bubble to pop-up. Completely disable or enable bubble on certain pages by creating flexible URL rules. Extension icon will turn gray when the bubble is disabled on the active page.
Results are being fetched from multiple sources simultaneously. There are 2 types of sources: content (text & images) and audio (pronunciation recordings or synthesis). Configure the order in which results from different sources are displayed or disable some sources completely.
📄 Supported content sources:
• Google Dictionary
• Google Translate 🆕
• DuckDuckGo Instant Answers
• Bing Images 🆕
• Google Search
• Custom 🆕
🔊 Supported audio sources:
• Speech synthesizer
• Google Dictionary Pronunciations
All audio sources have “autoplay” feature.
Expect more sources in future updates.
Results can be requested in multiple languages at once according to your preferences, and displayed in specific order. When there's no info in most preferable to you language, results in the next preferable language will be displayed automatically. You can also switch between languages manually for every single search result.
Customize the look of the extension, including bubble, options app, and popup window. Choose one of predefined themes or create your own with the built-in Theme Editor. Automatically switch between themes based on the time on your computer using scheduling feature.
Popup window opens when you click the extension's icon. It enables you to:
🔍 Search by typing the query instead of selecting it on a page.
✔️/❌ Toggle bubble activation behavior for currently opened domains and pages without manually writing URL rules.
🎨 Toggle themes and schedules without opening options app.
📄 PDF Reader 🆕
Definer can’t work in most PDF viewers, so it comes bundled with its own integrated PDF Reader that will let you use the pop-up bubble on PDFs.
To open PDF reader: click on the Definer’s icon → 3 vertical dots → “PDF Reader”.
- The bubble will not work in tabs that were open prior to installation. After installing this extension, it's recommended to restart your browser.
- All extensions are disabled on Chrome Web Store, including this page. Don't try to get the pop-up bubble to work here, it won't function.
