Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier in its niche. The only one that actually gets emotion right.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
