Koi Editor is a fast, native code editor for macOS that prioritizes instant typing and a distraction-free, keyboard-first experience. It runs entirely locally with no accounts or telemetry, supports local AI models via Ollama for code completion and chat, and can be extended with plain Python commands. Koi automatically reloads files modified by external tools, making it ideal for use with AI coding agents like Claude Code or Aider. With native macOS integration and flexible workspaces, Koi offers a responsive, private, and scriptable editing environment.
