Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-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.
