Why does a nonsense sentence with simple words score high?
Our program would score this type of sentence ok since all the words are commonly used words. Our premise is if it uses uncommon words then it is not easily comprehended. Of course logically constructed sentences with difficult words may be better than poorly constructed sentences with simple words. But since our program is meant to analyze thousands of words, the overall analysis would be more accurate.
Is this free?
Right now it is free for upto 1000 words. It probably will be a while before enough interest generates to justify charging for it.
