Kai's verdict	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier. Bet on this one — the Sparkpage format is genuinely new.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
