We propose to demo LARA (Learning and Reading Assistant), a set of tools currently being developed in the context of a collaborative open project for building and using online computer-assisted language learning (CALL) content. LARA offers a range of options for semi-automatically transforming text into a hypertext version designed to give support to non-native readers. The demo is intended to accompany our full paper about LARA; here we focus on describing some of the content we will present.
