  • Composer for multi-file edits
  • Runs Claude, GPT, Gemini — you pick
  • General-purpose agent — research, book, build, analyze
  • Parallel task execution
  • Web browsing + file creation + coding
Weaknesses
  • Developer-only

  • Can burn credits fast
Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.S-tier infrastructure. The one platform every AI dev eventually uses.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier in the agent category. The first one I'd give to a non-technical friend.
