Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier. Best for fast prototypes. Competitive with Lovable — try both.S-tier for solo + free. The best free option, hands down.
