Jim Lerman's insight:
I tried this out on some longish pieces...1000 words or more. The tool did a very good job of reducing several articles by about 50-60% in size, while preserving very well the meaning of the selection. I did this about 4 times and was quite impressed with the quality of the summaries. This could prove quite useful for students of all ages, as well as busy educators.
