| Kai's verdict | A-tier. The right answer if you want open-source + terminal-native + model-agnostic. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. |
