Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
