Kai's verdictA-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 if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
