A chrome extension to show online dictionary content.

Online Dictionary Helper (with Anki support)

[中文版说明]

Online Dictionary Helper is a Chrome/Firefox extension to show definitions for words and phrases from online (or builtin) dictionary via users' selection on any webpage and PDF documents (using pdf.js), which also supports flash-card creation using Anki (with AnkiConnect, an Anki add-on, installed).

Details on the reasons for making this extension can be found in the background introduction if you are interested.

What might set this extension apart is that users can grab online dictionary content with their own customized script (running under extension development mode). For development details, please check the development guide.
