The advanced text analyzer appears to be extremely helpful to me. However I need to analyze a text size of which exceeds the limits. Is not there any possibility to increase the number of characters? This is crucial since, I combined all the reading passages in Cambridge IELTS book and now am trying to sort the words according to frequency. Thus, we will reach the peak of efficiency in memorizing the words. The first 20 percent of the list, probably constitute more than half of the vocabulary.
It is a limitation of the text box.
Have you tried the old Range and Frequency programs from Paul Nation?
