Kai's verdictA-tier in its niche. The only one that actually gets emotion right.S-tier for designers. The only one that takes vectors seriously.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. S-tier if you self-host. The reason open-source image gen matters.
