Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Best for fast prototypes. Competitive with Lovable — try both.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.
