Definer - Word Finder, Translate, Ask AI, Images & Web Search Dictionary

Multilingual translator and dictionary for smart word searches. Ask AI, define text on webpages, and use the included PDF viewer.

Stop interrupting your reading flow to switch tabs just to define a word or translate a phrase. Definer is a powerful word finder and browser extension that brings the dictionary directly to you. Whether you are reading a complex article, studying a foreign language, or just need a quick synonym, this tool acts as your personal reading assistant. Simply select any text on a webpage to instantly trigger the popup bubble. Unlike a basic Google Dictionary extension, Definer integrates multiple data sources, allowing you to use it as a paraphrase tool, an encyclopedia searcher, or a translation hub. It streamlines how you consume content online, making it the perfect solution for anyone wondering how to search for a phrase on a website without losing their place. 🚀 Key Features ✅ Instant definitions with zero clicks—just select the text to see meanings ✅ Built-in AI paraphraser to help rewrite sentences and understand context ✅ Support for EPUB files to help you read ebooks in the browser ✅ Integrated PDF translator capabilities (requires using the bundled PDF reader) ✅ American Sign Language dictionary support for visual learners ✅ IPA translator to help you master correct pronunciation ✅ Advanced figurative language recognition for complex idioms ✅ Multiple search engines included like Wikipedia and DuckDuckGo Unlock the Power of Multiple Sources Definer goes beyond simple definitions by allowing you to customize where your data comes from. While many users look for a standard Google Dictionary experience, this extension lets you connect to a wide array of informational tools. You can perform a specific Wikipedia search to get historical context or use the Bing Image Search source to see visual representations of the selected text. If you value privacy and variety, you can toggle on the DuckDuckGo search integration. The extension also supports custom iframes, meaning you can add your own preferred data sources. This flexibility makes it far more versatile than a standard mouse tool or linguistic extension. AI-Powered Writing and Reading Aid Writing and understanding complex text is easier with artificial intelligence. Definer includes an AI grammar checker to help you verify syntax and structure. If you run into a complicated sentence, you can use the AI source as a paraphrase tool to simplify the language. This is incredibly useful for students and professionals who need to grasp difficult concepts quickly. The AI Paraphraser ensures you understand the nuance behind the words, not just the literal definition. Language Learning Made Easy For language learners, context is everything. Definer acts as a comprehensive multilingual dictionary that helps you bridge the gap between languages. If you are learning English, the English IPA translator feature is essential for understanding phonetic pronunciation. For those interested in non-verbal communication, the inclusion of a Sign Language dictionary makes this a unique educational tool. You can also use this tool to translate Google results or foreign news articles instantly. It is designed to be a robust translation software that sits quietly in your browser until you need it. By handling phrase search requests efficiently, it helps you learn idioms and figurative language that standard dictionaries might miss. Works on Specialized Formats Most extensions stop working when you leave a standard HTML webpage, but Definer works hard to be accessible everywhere. It includes a specialized reader that allows for PDF translator functionality, so you can read reports and papers with the same ease as a blog post. Additionally, it supports EPUB files, turning your browser into a fully functional ebook reader with instant lookups. 💡 Use Cases For Students: detailed research often requires checking multiple sources. Instead of opening new tabs to search Wikipedia or DuckDuckGo search engine results, get the info right in the popup. For Language Learners: Use the IPA translator and phrase search features to master pronunciation and usage. The extension serves as a complete linguistic extension for your daily practice. For Professionals: Use the AI grammar checker and paraphrase tool to refine your emails and reports, ensuring your communication is clear and professional. For eBook Readers: Load your books into the EPUB reader and enjoy a seamless reading experience where every difficult word is just a text selection away from a clear definition. ❓ Frequently Asked Questions How to search for words on a page? Simply select the text you want to look up using your mouse. The Definer popup will appear instantly with the definition or translation. Can I use it as a free word search tool for PDFs? Yes, but you must open the PDF using the integrated PDF reader that comes with the extension. This allows the word finder features to work on document formats. Does this work as a word search online tool for foreign languages? Absolutely. It functions as a multilingual dictionary and translation extension, supporting dozens of languages for both input and output. How to search for a word on a page using AI? Select the word or phrase, and choose the AI source in the popup bubble. You can ask for definitions, synonyms, or even ask it to explain the text like a tutor. Is this better than a standard Google Dictionary? Definer offers more customization. While it can provide similar definitions, it also offers AI integration, PDF support, and access to other search engines like Bing and Wikipedia. ⚠️ Troubleshooting Setup If something isn't working properly, here's what you can try: Restart your browser.
