On the spot Translator is a free Chrome add-on developed by uoneway. This handy tool allows users to quickly and easily translate text with just one click. By simply pressing the Alt key, users can instantly see the translation right below the original text.

One of the standout features of On the spot Translator is its intuitive design. Users can easily view both the original text and the translation at a glance, making it incredibly convenient for understanding foreign language content. This is particularly useful for texts that contain many jargon or technical terms.

Currently, On the spot Translator supports English to Korean and Korean to English translations, with automatic language detection. The translation is based on the Naver Papago API, so users are required to register with the Naver developers center and obtain the application Client ID and Client Secret. These credentials need to be entered into the extension's options for it to work properly.
