An adhoc cube browser tool

While all the PowerView dashboarding capabilities are very nice and highly used, majority of our customers are analysts who'd like to be able to browse through a cube to perform ad-hoc analysis. A need for an ad-hoc cube browser tool is very strongly felt in such cases. A parallel would be tools like ProClarity (while it was still available),Cognos Analysis Studio and even SQL Management Studio! We can't deploy Management Studio across all work machines for Business Analysts and no, Excel is not the best cube browser out there. Please provide a finer version of an ad-hoc cube browser so that people don't have to custom build their own.
