Kai's verdictS-tier for text-in-image. Use this for posters, Midjourney for art.A-tier for designer-led sites. S-tier if animations matter.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
