Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier inside Photoshop (Generative Fill). B-tier standalone.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
