The graphic user interface for text annotation is at the core of co-ment. You can test it live, in the frame below. To start with, you can either click on a highlighted area in the text to display the corresponding comment(s), or select part of the text and click on the square button on the left to add a comment. Feel free to try all other actions to see what they do.
Co-ment PRO provides a workspace where the collaborative work of a group on texts can be managed. A tabbed interface permits to access text editing directly when commenting. You can have a glance at these features by viewing the slideshow of screenshots.
