About this project

Actively maintained

This is an evolving project. I update it as I find bugs and add features that make it more useful and user-friendly. Check the GitHub releases page for the latest version.

How it was built

I'm comfortable with HTML and CSS, and have some Python and Swift experience. Parts of this app were built with help from AI tools. I'd rather be upfront about that than mislead anyone about how it came together.

Security

The app processes your media locally on your Mac. During development it was checked using Xcode's built-in static analysis and security tooling to catch code-level issues. It's distributed as an un-notarized build, so macOS will ask you to confirm on first launch (see the install steps above).

Common questions

Why does macOS say the app is from an unidentified developer?

The app is distributed as an un-notarized build, so on first launch macOS adds an extra confirmation step. Open System Settings → Privacy & Security, then click "Open Anyway." After that it launches normally every time.

Is it free?

Yes, it's free right now. That could change in the future, but anything you download today is yours to keep using.

Does the app send my files anywhere?

No. Everything runs locally on your Mac. The only two tools that need an internet connection are the YouTube Browser and the Video Archival Utility, since they fetch content from the web. Nothing else goes online.

Will it keep getting updates?

Yes. I update it as I find bugs and add features. The latest version is always on the GitHub releases page.

What do I need to run it?

macOS 15 Sequoia or later, on either an Apple Silicon or Intel Mac, with at least 4 GB of RAM (8 GB recommended).
