I looked at it, and I'm uncomfortable with the fact I have to be logged in, so you know all my search results, know my exact identity (through the credit card) and can analyze them and store forever (you can say you don't do that, but you cannot prove it). At least with Google I can delete cookies, disable fingerprinting and use a VPN, and hope they don't have my search history. Furthermore, you are in US jurisdiction, so the government can request access to your data and you can never tell anybody about that. What about a version of that where I pay a few cents for each search, using Lightning Network, for example?
