I'm not sure what you mean "It gets coded as green". It doesn't consider an entire statement, it considers word choice.

Similarly, it says that green means that it's placed in the "writing tone" evaluation category, in that it tries to determine whether the writing comes across as analytical, confident or tentative. More like instructions or analysis and less like judgment or conversation.

It's better to look at the demo in a different way. I mean, if I put your post into the analyzer it tells me that it's impassioned, and of that it's not very cheerful. If I put mine in, it looks very matter of fact. It's more analytical and matter-of-fact.

The two posts imply that kind of difference in tone, and it's pretty cool to see.

It's got a way to go, but trying different examples is interesting.

I mean that they are building a tool and the primary example is showing a typical passive-aggressive business email and the user is trying to make it worse.

This is a strange reason to write a tool, and perhaps symptomatic of the corporate culture that sought to produce it.

Teaching people to be nicer would be more interesting, and it's clear it is not dwelling on the right elements since it neglects to detect the overall tone of the email as being problematic.
