Sadly, this doesn't exist yet. You will find that most Natural Language Processing (NLP) tools conceptualize linguistic categories differently from how teachers do (language teaching isn't linguistics, there are often simplifications happening, and schoolbooks get updated more slowly than linguistics evolves). Examples: * English verbs have only two tenses: PAST or NONPAST. They can have PERFECTIVE aspect or not. They can have PROGRESSIVE aspect or not. Since these are 3 binary choices, there are at least 8 different ways how English verbs can be realized. I think there'd be less confusion in school if a more linguistically correct version was taught that separates out tense and aspects. * "Future" or "Present Perfect" (something I still got taught in school) don't exist for a proper linguist. To build what you suggest, existing tools could be combined, but there would have to be a mapping layer on top of syntactic parsers like Charniak Parser, Collins parser or MaltParser. Another mis-match between grammar in school and linguistics is single versus multiple theories: in school, people usually teach constituent trees, whereas in linguistics phrase structure (constituent) grammar is one theory among many, one alternative (valency and dependency grammar) that does not rely on trees but focuses on the relations between words has recently gained a lot of traction in linguistic circles.
