Scientific Writing Assistant

SWAN: http://cs.joensuu.fi/swan/

Intro: This Swan - Scientific Writing AssistaNt - aims at helping writers with the content, not the grammar or spelling. It guides you towards known good scientific writing practices and helps your readers find your contribution. The tool was designed to help you with your writing, not to merely point out errors. Using the tool should be simple; just enter your text sections into the tool, optionally make some manual elaboration and click the "Evaluate" button. Once you have used the tool with one of your own scientific papers, do let us know how it has helped to you.
