Little Tagger - Wait for An Update
Mac AppsI have long relied on the Mac power user's file management automation app Hazel by Noodlesoft to handle tag related tasks for me, but at $42 for a single user license, it might be a little rich for some who don't need all of its functionality. For those who simply want to automate some of their basic tagging chores, Little Tagger by indy developer Dennis Schäfer, which I just learned about, might just do the trick but read carefully.
Little Tagger works from saved profiles you create based on a menu-based interface. The profiles are saved presets that are reusable. Tagging works in single files or on whole folder trees you drag into the program interface or import via a keyboard combo. It defaults to the last used profile, but you can easily delay execution to edit the profile or select a different one. Not only can Little Tagger add tags to files, it can also remove them. It uses your already created finder tags as a base but allows you to create new ones with having to go to Finder to do so. Little Tagger features a tag cloud feature that you can activate and use to drag and drop files onto. If you're partial to a keyboard centric workflow, you can do almost every action in the app without touching the mouse.
One drawback to the program is that it has not been updated since 2022. The developer's web site has information about a fuller featured product he's working on, but it appears to be separate app and not an upgrade. No pricing info for the new app is offered, but there appear to be beta invitations available. Little Tracker's privacy policy states that the developer does not track any data at all from the app. It is an $8.99 one-time purchase in the App Store. My recommendation would be to see if you can get in on the beta of the developer's app in progress unless he updates this one before then.
