Extension summary

Word Discoverer highlights rare English dictionary words, idioms and proverbs on web pages. It helps non-native English learners to discover new expressions while they are browsing the Internet. Highlighting of rare words is useful because some people do not even notice vaguely known words, especially when these words are not critical for understanding of the text that they read. One possible explanation of this strange and pertexing effect is that mind of a reader is concentrated on understanding the meaning and structure of the text, and after finishing reading a sentence many readers won't go back to check the meaning of unfamiliar words that they have already forgot. E.g. some readers will forget to check the definition of word "pertexing" from the previous sentence which, in fact, doesn't exist. And even if you did check it, you still can try this extension, it highlights only real English dictionary words and idioms =)

NOTE On installation Words Discoverer shows scary warning that it can "read and change all you data on the websites your visit" - don't worry, Words Discoverer will not send any of your data anywhere. In fact it doesn't even talk to any servers, all highlighting logic is performed locally in your browser, so if you have some saved html files to read, you can even use Words Discoverer offline. The source code is here if you are curious: https://github.com/mechatroner/aided_reading

Words Discoverer is free forever, open source, and it has no ads.

Here are some features of the extension:

Words Discoverer is better than "Word-of-the-day" type of programs because new words are highlighted in context of the text that you read, which is a good motivating factor to finally check the definitions and learn these words (or idioms).

Depending on your vocabulary size, you can adjust frequency threshold of highlighted words e.g. skip 25% most common English words, and highlight all the rest. There's no way to set such threshold for idioms and proverbs, the extension can either highlight all of them or none.
