Thanks for sharing. This might be the push I needed to give them a try. They do seem to be using Google indirectly:
Serper: Based in the UK (Europe but not EU) and using anonymized Google results, we skipped adding them for a while, but the reality is that a decent percentage of customers wanted a result experience similar to “old” Google (before all the AI stuff) and DuckDuckGo.
So I would imagine search quality should be good enough.
