WriteBetter is a tool to improve English learners’ writing skills.
It allows users to check their texts by means of a variety of English corpora, which show how to use words or expressions in real contexts. WriteBetter also has a function with which users can explore the most frequent structures related to the word searched. Users can also enrich their texts by looking up words in an integrated dictionary, which provides definitions, synonyms, and examples. This dictionary is WordNet, a large lexical database of English published by Princeton University under WordNet 3.0 license. The corpora that WriteBetter uses are Wikipedia articles, and around 3,000 English public domain books.
