Today, when I tried to use the non-logged in google adwords keyword tool to do some on the fly KW research, it got immediately redirected to Google account login screen.

According to this article , the keyword tool was redirecting to Planner Tool. When I tried to get to adwords keyword tool, while logged in, it worked fine. ...it would be weird for them to remove the keyword tool, the planner is a different thing....to me anyway...
