Bleh, presearch is tied to crypto nonsense. I think something like YaCy is a more viable project. I can't say if one is better than the other functionally, but I feel like anyone trying to get away from Google is doing it because of the excessive monetization messing with their searches, to then switch to something built to prop up a token/coin seems a bit strange imo.
Presearch has been my default search engine for over a year. It is a functional replacement for Google, but not without its quirks. Image searches are vastly better on Google in my experience. And I still search frequently on Google Maps for data that is heavily influenced by location.
