I like products like this, though English is a notorious pain in the ass to try and write, so I thought I'd try it out. In good news, this app does a good job of handling complex sequences. Consider the sentence: The quick, brown fox ran out of the clump of trees, saw us, got scared, and promptly ran back into hiding. When I typed that, I expected it to turn red, but it didn't. Great job! However, there is a problem with identifying adverbs. Consider the sentence, "He is a burly man." In this case, though burly ends with -ly (like adverbs), it is an adjective.
