In this paper, we present an automated tool with human supervision to write in plain language or to adapt difficult texts into plain language. It can be used on a web version and as a plugin for Word/Outlook plugins. At the publication date, it is only available in the French language. This tool has been developed for 3 years and has been used by 400 users from private companies and from public administrations. Text simplification is automatically performed with the manual approval of the user, at the lexical, syntactic, and discursive levels.
