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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
