LiuChan Chinese Popup Dictionary

LiuChan (liú chàng) is an extension for chrome that allows you to mouse-over Chinese to instantly lookup the dictionary.

It started out as a port of RikaiChan (and its Rikai derivatives) and has since grown into an extension that holds its own with new features and improved performance.

Current Features

  • Instantaneous translation of Chinese characters and words on mouse over
  • Synchronized settings across all your devices
  • Text input support
  • A handy little notepad that you can open on any page :)
  • Theme support
  • Fuzzy search! Use chrome's omnibox to search the dictionary using hanzi, pinyin or just plain english


Mouse Over Dictionary: Simply enable the extension and mouse over Chinese on a page!

Fuzzy search: Type 'lc' in the omnibox followed by whatever term you want to look for (Chinese, pinyin or English), the results will show up as suggestions.

To Do

  • Add word lists/Anki support
  • Move fuzzy search to its own input box as opposed to omnibox so that it can be expanded upon (eg. use rich formatting, etc)
  • Improve performance
  • Improve fuzzy search to match regular vowels with tonemarked pinyin
  • Update CEDICT

Why is it called LiuChan?

流畅 (liú chàng) stands for fluency in a language. I kept -Chan as an homage to it's origin.


If anything malfunctions, your best bet is disabling and re-enabling the extension and reloading the page you want it to work on.

In case a problem persists please open an issue on github and try to describe as clearly as possible how to recreate the problem.

Known issues:

Currently fuzzy search isn't 'fuzzy' enough to match regular vowels with tonemarked ones.

You can’t perform that action at this time.
