I just tried to use this, and it just feels wrong. It only allows a small amount of top level domains, and the domains that come out of it feel corporate.
Thanks for the feedback, I added a handful more TLD's, but need to think harder about the UX for the full list.
The corporate feel is interesting, maybe adding a tone dimension like formal, neutral, light hearted could be interesting.
You can also add the tone to the description although that's not obvious, I was thinking of adding some examples to help.
