Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier for open-source model APIs. The default in this space.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
