Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
