Aka is a Chrome extension designed to help users learn vocabulary in context while reading in a foreign language. Unlike traditional translation tools, Aka focuses on the surrounding text to provide accurate definitions, idioms, and examples relevant to the selected word or phrase. This contextual approach ensures that learners grasp not just the meaning but also the application of words in various scenarios, making it a valuable tool for language acquisition.

To use Aka, simply install the extension, which activates automatically upon installation. Users can highlight any word, phrase, or expression, and a button will appear, allowing them to access its meaning and contextual usage examples. It is important to note that Aka does not function as a full translator and is intended for individual words or phrases rather than entire paragraphs.
