A portable word processor, often called a portable keyboard, is a lightweight device that is an alternative to using a laptop computer for writing. It can be easily transported from class to class and between home and school. The size of the screen varies depending on the specific device. The text is usually auto-saved and can later be revised and/or sent directly to the printer. Text may also be uploaded onto the computer through any word processing program and edited and saved as needed. Text from the computer can also be downloaded to the portable word processor. In addition, a built-in spell check is included to assist students in editing their writing. Word processing allows the user to edit and correct his written work more efficiently than doing so by hand. Most portable word processors have keyboarding programs available.

Portable word processors can be helpful for students with writing difficulties, who often require an alternative to pencil and paper. They are a good solution for students who have poor handwriting and prefer to use a keyboard. Students with attention deficits may also benefit from this solution.
