You are aware that if you're paying for kagi you can just slap !ai at the end of any search query and it'll direct the query to kagi.com/assistant, right?
And that you can set the model to answer those query as any of the grok models?
Kagi isn't behind anyone else on this AI-powered search, in fact the assistant is nearly a strict superset of all the other ones.
You can set the model to chatGPT, claude, gemini, grok, etc. And it'll use kagi search as a backend instead of, respectively, bing, brave, google, google+twitter.
