| Kai's verdict | S-tier. Market leader with reason. Start here for serious video. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. |
