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. The right answer if you want open-source + terminal-native + model-agnostic.
