Weaknesses
  • Terminal-based — learning curve

Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for model-shopping. I use this for every prototype before committing.S-tier for designers. The only one that takes vectors seriously.S-tier for builders. The right primitives. What Kai is built on under the hood.
