Founder here. Thanks for submitting it, but I am afraid there is not much to see right now.
We are still in closed beta (mostly to control cost and gradually improve user experience), with much more left to do. There are some examples of what Kagi can do in my twitter feed. [1]
Main idea of Kagi is to offer a paid search product, where user is also the customer and is central to everything that happens. Btw. Kagi is pronounced ka-gi (similar to yogi), I get asked that a lot so there it is...
If you want to beta test, feel free to sign up and we will do our best to send an invite within a week.
How is it better than using a proxy server to access Google?
