Tapword Translator

Tapword Translator is a browser extension that translates selected text on a web page inline, placing the result directly beneath the selected words like a note in the margin of a book. It does not open a pop up bubble over the original text, and the vendor describes it as built for close reading and language learning rather than for translating a whole page at once. It supports Chrome 88 and later, Edge 88 and later and Firefox 90 and later. It is aimed at people reading in a foreign language. A language model reads the surrounding sentence so the translation reflects context, tapping anywhere in a word selects the whole word, and selecting a single word shows its phonetic spelling, parts of speech and full meanings with example sentences from the source text. Selecting a sentence or phrase switches to inline translation. A PDF translation page is also offered, and a whole page translation feature is marked as coming soon. The site is available in several languages including Chinese, English, Spanish, Japanese, French, German, Korean and Russian. The extension is free and requires no account. An official cloud translation service works after installation with no setup, and the vendor states it does not store translated content. Users can instead enter their own API key from providers such as OpenAI, DeepSeek or Moonshot, in which case requests go directly to that provider rather than through the vendor's servers. The community edition is open source, and an offline installer is available for users who cannot reach the Chrome store.
