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