This is amazing, Franklin. As a domain investor - smart brandly is going to help me a lot. The fact that you can see if the domain is available right from the web app (without having to go to GoDaddy or Dynadot to do that) is no less than genius!
Do you also plan to add "TLDs Taken" number? I.e. show in how many TLDs (com,org,io,net, etc) this domain is taken.. It might help understanding the value of each domain better :)
