Kai's verdictS-tier for realtime. If latency matters more than voice catalog, start here.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier inside Photoshop (Generative Fill). B-tier standalone.
