Kai's verdictS-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Market leader with reason. Start here for serious video.
