Bing Has a Free Keyword Research Tool in Bing Webmaster Tools
https://www.bing.comApparently, it has been there for a while, I don’t often use Bing WMT, they do offer some good tools in there but traffic from bing is minuscule for my sites. So if you need to check some keyword data directly from Bing this might be a good resource to keep in your tool belt.
