Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
