Hey everyone! 👋 Super excited to be launching Substage on Product Hunt today! It’s a natural language command bar that sits just under your Finder windows and lets you interact with your files and folders using plain English. You can say things like:

  • Convert to webp

  • Word count?

  • zip these up

  • I think I gave this image the wrong file extension. What file type is it really?

  • Download this here: <some file url>

  • Make a new readme.txt

It’s fast, context-aware (uses your current Finder selection), and smart enough to suggest safe Terminal commands — with built-in risk assessment (for example, it'll never `rm` anything, only `mv` to Trash if you ask it. By default it works with popular AI providers, but you can choose to use it with local LLMs too.

During my day job as co-founder of indie game dev Inkle Studios, I’ve found it super useful for converting videos and images, checking metadata, and more. Although I’m a coder, I’ll avoid using the command line whenever I can 😅 So although I understand that there’s a lot of power beyond the command line, I can never remember the exact command line arguments for just about anything.

It's free to try, so I’d love to hear what you think!

@joethephish Congratulations on the launch of Substage, Joe!
The context-aware command processing is the best feature to me as it will help users to streamline their file management without digging into the command line. To enhance creativity you can consider integrating a way to create custom commands or shortcuts for frequently used tasks.
Wishing you and your team all the success with this innovative tool!

Thanks@shadmannazim ! Yup, the groundwork is laid for custom commands since in the past week I have added the ability to cache existing commands in history for immediate re-running instead of asking AI again. So it's absolutely something I want to add!

This is a super savvy gesture towards what the future of Computer Use can look like... like an OS-level Clippy without the irritation!

It's like when the CLI reaches up to help Finder tackle everyday chores.
