Earlier quoted context omitted.
Kagi ( https://kagi.com ) has very similar tools with their "Lenses" and customizable prioritization of specific domains.
Kagi is a weird beast. I'd like to use it but I also don't understand how searches are private if I have to login. Not understanding that is definitely on me but I feel like it should be a frequent enough question that they try to make the answer obvious.
PS: I am not a lawyer, but for what it's worth, if you _pay_ for Kagi and they advertise their privacy policy as a feature you pay for (see https://kagi.com/privacy), one could reasonable sue for false advertising or demand a refund for not providing a promised service. This would make any pushback subject to consumer protection laws in addition to whatever nascent privacy law they may be subject to.
