You can download the Microsoft Power BI Desktop here. It is over 300MB, so it might take a few minutes to download. Power BI Desktop is free of charge.

We can also, use the Power BI service, and we are able to bring our reports, onto the web, and then create dashboards from several different reports. And again, this starts from free. You only have to pay if you want to share it. Both the Desktop version and the service version are fully featured.

So with the Power BI service, you can create projects, called workspaces, and be able to package this up into apps, and send it read-only, to other members in your organization. You could even share it on the web if you so chose.

There are three components to Power BI Desktop: the query editor, modeling and calculations side, and thirdly the visualization side. If you an avid Microsoft Excel user of power pivot, power query, and power view then Power BI will be fairly easy for you to learn. Essentially, Power BI is a combination of all three of these. You do not need to back and learn Excel’s power tools to be able to learn Power BI.
