About Nuenki

Nuenki is a browser extension for people learning a language who want practice without setting aside extra study time. It translates sentences on the pages you already read, so ordinary browsing becomes a steady source of exposure to your target language.

It starts with short, simple sentences and translates more as your ability grows. Hovering over a translation reverts it to English, and tapping a highlighted sentence reveals the English text. The site lists 46 languages with dictionary lookups, audio, and Pinyin or Furigana where they apply, and it offers playful variants such as Pirate English and Klingon.

Nuenki says it skips sensitive pages and sentences and does not link translations to a user's identity. The product is offered with a seven-day free trial and no card required, and it works on Chrome and Firefox.
