Niche Directory Finder

I saw a website link on this forum for a site where you can type in a keyword and it will list the top sites and directories they belong to.
This was a paid site but there was also a free search where some of the listings are blurred out.

Does anyone know what site I'm talking about or one similar to this.

I can't find the post with the link and I don't remember what the site was called.

Thank you

ok. I found it.
Does anyone have any experience with this site.
