This plugin creates a button on your website which enables the reader to turn on a bilingual dictionary. Whenever the reader clicks on a word they will see instant translations to their language displayed neatly in a pop-up box on top of your content.
There are many learners of English who just need help with the occasional word and don’t want to translate the whole text to their language – which often results in numerous errors. This is why mouseover dictionary translation extensions have been so popular on the Chrome Browser. However, these great apps are often limited to support only Chrome and only its desktop version. Extensions are not available on mobile devices, yet most content is now consumed on mobile devices. This plugin will increase your engagement with non-native speakers on all browsers on all devices.
After installation you will have 1,000 calls per month to our API for free. The premium version increases this to 25,000 calls per month.
<h3>Features</h3>
<ul>
<li>The only extension compatible with all browser types. No matter if they’re on mobile or on desktop, definitions are now instantly available to everyone, everywhere.</li>
<li>Fully optimised for mobile and desktop. On a desktop the button reads “click to translate” and on a mobile device it says “touch to translate” but the functionality is the same. The user can scroll down within the popup box for additional detail on each word and to see sample sentences.</li>
<li>Easy to install and easy to use. Just a few clicks and creating a user account for the API key will see this plugin operating on your website.</li>
<li>Our dictionaries are vast. We have created bilingual dictionaries by combining Wiktionary, Wikipedia and other creative commons sources to create one of the most up to date and comprehensive databases in the world. Depending on the language, our dictionaries have between 300,000 and 700,000 headwords and many headwords have multiple definitions.</li>
