Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier in its niche. The only one that actually gets emotion right.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Still early. Manus is more flexible for less money.
