You have two options to export your text from AutoCrit:
Option 1: Export with a file open.

With a file open, the export button is located in the upper right-hand corner of your screen.
Here you can choose to export the file in a variety of formats (.docx, .rtf, .txt).
You also have an option to export the visible AutoCrit highlights with the text. For this to work, the highlights must be currently visible on your screen.
The exported file will be saved wherever your browser saves downloaded files.
Option 2: Export files from the main Project File Menu.

You can export your file directly from the main file management window as shown above. This allows you to export without the need of opening every file first.
You can choose to export the file in a variety of formats and the exported file will be saved wherever your browser saves downloaded files.
