Sotu - Translate, save and learn

Highlight any word on any website to instantly see its meaning without leaving the page. Unlike traditional translation tools, sotu also considers the sentence containing the word. This allows it to understand whether "bank" refers to a financial institution or the side of a river, and show you the meaning that actually fits what you're reading. Every word you look up is automatically saved to your vocabulary notebook. The Review page sorts words by how often you've looked them up, so the words you struggle with most appear first. Supports English, Korean, Japanese, Chinese, Spanish, and Vietnamese, with translation in both directions. Sign in with Google to sync your vocabulary notebook across devices.
