Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
