Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.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. Close second to Cursor. If $5/mo matters, start here.
