Best forDevelopers experimenting across models. Apps that want fallback logic.Designers already on Figma.Developers who want an agent, not autocomplete. Large refactors, tests, docs.Developers using open-source models (Flux, SDXL, Whisper, etc).

  • Rename/rearrange layers automatically
  • Natural language asset search
  • Runs locally, edits your actual files
  • Strong on large codebases with 1M context
  • Great at multi-step tasks
  • Tens of thousands of models (image, video, audio, LLMs)

  • Cog framework for custom model deploy
Weaknesses
  • Slight markup over direct API
  • Some provider features not exposed

  • Pricing gets real at scale
Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier. No reason not to use it if you're on Figma. Not worth switching for.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for open-source model APIs. The default in this space.
