I built Happy Docs a while back for documenting APIs. It's still a work in progress. It mostly gets used for internal projects, so there isn't a good public example yet that showcases all of the features, but it includes a query tool (a bit of a work in progress), several authroing/editing tools, collaboration, and a few different export formats. http://happydocs.net http://happydocs.net
