Name of search visualization tool mentioned at INBOUND18?

[#1]

There was a great online tool mentioned at INBOUND18 and I can't for the life of me find it.  You type in a topic and it produced a very cool and useful visualization of the many different search variants and related search terms for that topic.  

I really liked the way the info was displayed. Ring a bell with anyone?

If you're talking about the HubSpot Content Strategy tool for building Topic Clusters, you'll find a nice article on that from the guys at BluLeadz -- a HubSpot Diamond Agency Partner.

If not, maybe consider zipping through the INBOUND18 presentations by Brian, Dharmesh, and Christopher.

The moment I saw the guy with the white beard on their landing page I knew you had it. That's it!  Bookmarking now.  Thank you Shahllak!
