Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.A-tier. Close second to Cursor. If $5/mo matters, start here.
