Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Still early. Manus is more flexible for less money.S-tier for speed. When latency is the product, start here.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
