Kai's verdictS-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for builders. The right primitives. What Kai is built on under the hood.
