Substage 1.2.3 for Mac
Mac UtilitiesSubstage sits below your Finder windows and lets you describe file jobs in plain words. Select a few videos and type a request to convert them, ask what codec a file uses, or tell it to tidy a messy folder. Substage turns your words into the right Terminal command, shows you what will happen, and runs it only when you are happy. It brings the power of the command line to people who never wanted to memorise its syntax.

- Convert images, video and documents and inspect file details with short prompts
- Use your choice of AI models, including local models through Ollama or LM Studio
- Save custom rules and instant actions for jobs you repeat every day

System Requirements
Substage needs a recent version of macOS, and the vendor lists macOS 15 or later. Some tasks use AI services or local models, so check the official site for setup details and current requirements before you install.
FAQs
Do I need to know Terminal commands?
No. You describe the job in everyday words and Substage builds the command. Reading the preview before it runs is still a wise habit.
Does Substage send my file contents to AI services?
The vendor says it sends your prompt and file paths as context, not the contents of your files. Local models can keep even more of the work on your Mac.
What jobs suit Substage best?
Quick single tasks suit it best, such as converting a file, resizing images, zipping a folder, or asking questions about selected files.
