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.

Can you please add DeepL as a source?
Me ha sido de mucho utilidad, pero sería grandioso que pudiera añadir más Recursos personalizados, ya que solo permite añadir uno.
Functions that can enhance user experience: (1) Function to save searched words. (2) Manual search bar on within popup to search word other than selected
Весьма симпатично. Пользовательскую ссылку всячески поддерживаю, более того, позволил бы неограниченный список таких ссылок. И, пожалуйста, сделайте регулировку размера шрифта.
Dictionary, translator. wilkipedia and google search engine all in one extension. Amazing, loved it. Also there should an app like this for smartphone use.
Отличное приложение! Можно добавить в настройки назначение нескольких клавиш при переводе предложений. Great app! You can add in the settings assignment of shortcuts when translating sentences.
I love being able to rate an extension 5 stars. This one definitely deserves it. Well done, dev!
Amazing ..... I used it mostly for pdf reading.... keep up the good work and the best thing is that the extension is completely free !!!
Best translate extension for browser
Is it possible to adjust the text length limit? I use it as a popup translator, the string is truncated.
