Substage
Substage is a Mac utility that adds a natural-language command bar to Finder so you can organize, convert, and manage files with guided Terminal actions.
What is Substage?
Substage is a native Mac utility for working with files in Finder using natural-language requests. It helps users describe a task in plain English, then generates a Terminal command for actions such as organizing files, converting media, creating archives, and finding matching items. The app is aimed at Mac users who want faster file management without memorizing shell commands, while still keeping control over what runs. Substage also includes shortcut-based instant actions for common operations and can preview likely side effects before you confirm an action. Built-in AI features may send your prompt and limited file-context details to an AI provider, while the app itself is designed for local Finder-based workflows rather than cloud storage or remote administration. Substage is published by Selkie Design Ltd for macOS.

Safety overview
Status: Mostly safe
Substage is a legitimate file-management utility for macOS. Because it can generate and run Terminal commands, it can make real changes to files and folders when you approve an action, so it is best used carefully on important data. Access related to Finder control and file handling is consistent with its purpose, but AI-powered requests may send your prompt and limited file context to an external AI provider. Review actions before confirming them, and keep backups for folders you would not want changed accidentally.
Recommendation: Keep Substage if you use it to speed up Finder and file-management tasks on your Mac. If you no longer rely on natural-language file actions or command generation, you can remove it without affecting macOS itself, though any app-specific settings and workflow conveniences will be lost.
