We need tools like www.seochat.com.
I need "embedable" tools. Which means that they are just like the ones you are creating except that they user can ALSO use it on their own website.
I have attached image. It shows the tools [login to view URL] has and how it is embedable. They also place a link on the tool which would bring the user back to my website. So, basically whenever webmasters embed the tool on their website, it creates a link back to my (which increases my link popularity)
