Nice.

The speed is really impressive, at least for the queries I tried. There are still a lot of queries with no results, and you might want to think of something clever to put there in those cases to keep the user turned onto your brand. When there are results, they seem quite relevant and useful.

The "Show me how it works" tour is great too.

I think you just need to work on your value proposition on the landing page. Don't be afraid to sell something. Put together few paid packages as soon as possible. Don't worry if it's not perfect.
