Kai's verdictS-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 model-shopping. I use this for every prototype before committing.A-tier in its niche. The only one that actually gets emotion right.
