Kai's verdictS-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier if you already pay Gemini. B-tier standalone.A-tier in its niche. The only one that actually gets emotion right.
