Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
