Overview
Product summary
Review the store description, core capabilities, and common use cases.
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

Great App. Thank you for making it easier to learn word. It would be lovely if it automatically saves the searched words for future reference.
excelente
so helpful, useful, and so configurable! I use it everyday! However, some suggestions pls: 1. Bing search 2. Perplexity search 3. ChatGPT search 4. And please, allow users to export config as file locally, and on cloud like google drive backup!
مفيد جدا للبحث السريع بدل الدخول علي ويكبيديا والبحث في جوجل
Exelente extensão.
the best extension ever that simplify many things....thank you .
Add ChatGPT create your own prompt option., your pdf reader is very good. but sider has a chatgpt pop up prompt that enables you to create your own prompt and the sider extension doesnt work on your pdf reader. please let other extensions access your pdf reader. so that i use other extensions on my pdf.
very good. hope you can add in more engines to choose from. such as the chatgpt and, please add a function that user can quit it by press "esc", or it quit automatically when the mouse left the panel.
First time I'm leaving a review for a chrome extension. It is so unbelievable how useful this tool is and how feature rich it is. All for the price of free!! The best extension I've ever gotten
Hi bro, this is neat and solid work. Congrats. Features needs to be 1. Hover (mouse hover) option to show Definer popup. 2. Allow access to PDF and Epub so we can access whenever wanted, unless need to upload every time. 3. How about separate app for PC like Qtranslate ( i personally hope this happens)
