About

Koi Editor is a fast, minimal, scriptable code and text editor for macOS, designed around low typing latency, large-file performance, and local workflows. Koi provides multi-cursor editing, multiple synchronized views of the same document, project-wide search, file and buffer navigation, syntax highlighting, code completion, configurable themes and keybindings, and extensive text-editing commands. The editor is designed to remain responsive with large source files, logs, and structured text, and has been tested with files containing tens of millions of lines while retaining syntax highlighting and core editing functionality. Optional AI features support local models through Ollama for code completion and inline assistance. Koi can operate entirely offline, requires no account, and includes no telemetry. Koi is built specifically for Apple Silicon Macs and combines a custom editing engine with native macOS integration.
