一个纯英文的浏览器翻译插件,给非母语的英文学习者用于营造英文语境

RunAway is an English-first dictionary extension designed for uninterrupted web reading.

Select or double-click one English word on an ordinary web page. RunAway opens a compact tooltip near the selection and shows an English definition first. If the dictionary entry includes them, you can then reveal an example and a Chinese translation. Immersive mode hides Chinese so you can remain in an English reading context.

Highlights:
  • English Definition first, followed by optional Example and Chinese.
  • Drag selection and double-click lookup on ordinary HTTP/HTTPS pages.
  • Shadow DOM tooltip designed to remain readable across different website styles.
  • Global ON/OFF toolbar control with locally saved preferences.
  • Clear not-found and network-error behavior.
  • Source and license links for real Wiktionary-derived results.
  • No accounts, ads, analytics, cloud sync or persistent lookup history.

Privacy by design:

RunAway processes only a word that you actively select. For a valid lookup, it sends the normalized word to the experimental FreeDictionaryAPI service. It does not send the page URL, title, full sentence or surrounding text. The enabled and immersive-mode settings stay in browser local storage.

Current limitations:
  • Desktop Microsoft Edge and Firefox only.
  • Single English words only; no phrases, names, PDFs, OCR, video-image subtitles or editable fields.
  • Definition, example and Chinese coverage varies with the underlying Wiktionary data.
  • FreeDictionaryAPI is an experimental preview provider and has no RunAway production SLA.
