I didn't realize who I was replying to, my apologies. I honestly haven't had much of a chance to play around with the new Kagi interface yet, so I can't speak too much to that. Though Perplexity Pro can pull in dozens of sources collected through a series of searches with the intent of finding different parts of the question. It also has support for a lot of things like generating charts and tables, running code (quite new, haven't done that myself yet), etc.
I have just found the quality of both the UI/UX as well as the answers themselves to be really great with Perplexity, far surpassing was I experienced with the previous (not this newly released) "Expert" assistant in Kagi.
