Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
