By default, Box lets you make edits right in your web browser.
In addition, Box offers "Box Edit," which is an add-on feature that allows you to edit or create files directly in Box. Box Edit uses the default applications, such as MS Word, already installed on your computer to edit or create simple and centralized content. Box Edit works with both Windows and Mac, and all major browsers.
Currently, Box Edit only works on web browsers and Box Embed. It is not available for mobile devices. However, Box OneCloud partners provide Box Edit-like functionality on mobile devices, such as CloudOn or QuickOffice (see Tufts Box Apps).
