Kai's verdictS-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. Best for teaching a kid to code in 2026.S-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.
