Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for realtime. If latency matters more than voice catalog, start here.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.
