What makes it a Mac app
-
Drag & drop
Drop your audio files, or a whole folder of chapters, right onto the list.
-
Finder Services
Right-click a folder in Finder ▸ Create Audiobook with Binder — no need to open the app first.
-
Multiple windows
Every book opens in its own window, so you can line up and build several at once.
-
Reorder chapters
Drag rows up or down to set the running order before you bind.
-
Drag-on cover
Pull any JPG or PNG onto the cover well; it’s written straight into the M4B.
-
Native & quiet
Hidden title bar, real macOS vibrancy, and it keeps exporting in the background while you work.
