AutoShelf

AutoShelf is a Mac app that moves files according to rules you define. The homepage gives examples such as filing invoices, sorting screenshots, and trashing installers. It also describes drop zones, a dry run that shows what would move before anything changes, templates, and rules that read text inside files or photo EXIF data. The same page states the price directly: free with 1 rule, or $19.99 once for unlimited rules. That is an ongoing free tier plus a paid upgrade, so the model is freemium. The app is installed on a Mac, so the platform is Desktop. It is a file-routing utility, not a general AI assistant, which is why the category is automation.
