Best forDevelopers. Non-developers who want to ship working code.Developers who want an agent, not autocomplete. Large refactors, tests, docs.ChatGPT subscribers experimenting with cinematic shots.Developers experimenting across models. Apps that want fallback logic.

Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for model-shopping. I use this for every prototype before committing.
