Earlier quoted context omitted.
This is very recently free, and I find less sources than you.com or perplexity in my experience.
Quality over quantity perhaps? Can't see why you'd want _more_ than about 3-5 sources returned each time. Anything more is information overload and defeats the purpose of being able to vet the claims in a timely manner.
Anyway. I want more and you.com and perplexity does that so I will use them over chatgtp.
