FoxType is an online tool that rates the politeness of written text and recommends more polite options when necessary. The tool rates the politeness of the text on a 0 to 100 scale as well as indicating whether it is “Impolite,” “Neutral,” or “Polite.”
There is also a Gmail plugin version of the tool that users can request via email through the FoxType site.
To demonstrate the tool, we have tested a number of famous movie quotes to see how they rate on the FoxType politeness scale.
