Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
