This reminds me of the "Hemingway" app that failed Hemingway: http://languagelog.ldc.upenn.edu/nll/?p=10416

Can I also just point out that "I was exhausted." is not passive voice! And "Our work here is done." also shouldn't be highlighted, it's absolutely fine. What the hell? With these kinds of false positives, this seems like it would do more harm than good.
