The 
External actions allow you to extend PDFix functionality with external modules, harnessing the power of AI.
You are able to create your own private actions and use them inside your local PDFix Desktop application to automate processes. Or you can download the publicly available external actions and use them to enhance your workflows.
PDFix offers several predefined external actions, which are continuously added to our Pdfix Actions Marketplace. Feel free to check them periodically.
