Kai's verdictA-tier. Great price/performance. Go here if ElevenLabs is too expensive.S-tier for builders. The right primitives. What Kai is built on under the hood.B-tier. Still early. Manus is more flexible for less money.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
