I know there are several similar tools for D&D 5th Edition but at the same time, Paizo literally gives AoN its blessing for its community to use its free tools on AoN to run campaigns, look up monsters, and create characters. Whereas WotC...wants creators money. Or they don't (honestly, that whole OGL situation has made me completely lose trust in WotC as a company to actually create things)
