A variety of written material was evaluated with five writing-assistance software packages. Three of the packages were found to be of limited value; they operated at a superficial level and cost much money. Of the remaining two, one was judged potentially valuable, although it was embedded in a larger system designed to teach writing to college students. The other one was judged a best buy on the basis of helpfulness to writers and minimal cost. Software is still no substitute for a good human editor.
