How is Incognito different from pTokens?

Maybe this is a silly question, but I am curious how Incognito is different than pTokens? It seems to me that they operate in almost exactly the same way. Does PRV work off of the pToken platform? Does it offer some specific dApp features that expand off of the ERC-20 tokens? Or is it completely different?

Incognito hosted an AMA with pTokens about a month ago.
