YaCy does a pretty good job, and is free, and you can run yourself, so the quality/experience is pretty much up to you. Paired together with a local GPT-OSS-120b with reasoning_effort set to high, I'm getting pretty good results. Validated with questions I do know the answer to, and seems alright although could be better of course, still getting better results out of GPT5.2 Pro which I guess is to be expected.
The point of my comment was that the AI/LLM is almost irrelevant in light of low quality search engine APIs/indexes. Is there a way to validate the actual quality and comprehensiveness of YaCY beyond anecdata?
Yeah, if that's how you feel about your own abilities, then I guess that's the way it is. Not sure what that has to do with YaCy or my original comment.
I assume that should be qualified with some basic amount of evidence beyond “I said so”? Anyways, thanks for pointing me in the direction of YaCy, will try it out.
