Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
