About

Koi Editor is a professional text editor for Mac, built around three principles: fast, local, and scriptable. Koi is designed for responsive editing from ordinary source files to very large documents. It includes multi-cursor editing, synchronized views, project-wide search, context-aware autocomplete, syntax highlighting for 30+ languages, code folding, file outlines, configurable themes and keybindings, and extensive editing commands. Koi requires no account, includes no telemetry, and can operate entirely offline. Configuration and keybindings are plain text, and custom editor commands can be written in Python. Optional AI features connect directly to local models through Ollama for code completion and inline assistance. Built specifically for Apple Silicon Macs, Koi combines a high-performance editing core with native macOS integration.

About

UltraEdit is a text and code editor built for work that general-purpose editors often struggle with: large files, complex data manipulation, and security-sensitive workflows. It has been in the market for more than 30 years, is used by over 4 million users worldwide, and is trusted by enterprise customers across the Fortune 100, 500, and 1000. Individual users choose UltraEdit when everyday editors start to hit their limits. Common use cases include working with very large files, running advanced search and replace, using column and block editing, and handling more complex text and data manipulation. Organizations choose UltraEdit when they need a more secure and supportable editor behind sensitive workflows. That includes teams in banking, insurance, healthcare, government, and other regulated or risk-sensitive environments where unsupported tools can create too much uncertainty.

Pros & Cons from Real Users

Pros

  • Does all that you want and need in an editor. Handles huge files search and replace, different filetypes etc.
  • Customizable User Interface. Great for any text editing & manipulation. Supports code formatting for all major languages. Built-in File comparison tool. Macro recording feature for automating tasks. Available across platforms & operating systems.

Cons

  • Too many updates, other than that it is great, they do not need to make all those updates.
  • No free version but they do offer a 30 day trial period. Takes some time to get used to due to overwhelming number of features.
