Primer Prep
PrimerPrep allows you to load sample text files in a language, and can immediately show the “optimal” teaching order and which words (from your texts) are available for each lesson. You can literally have useful results in under a minute. But there are also numerous options for fine-tuning your results, including identifying word-break characters, digraphs, and affixes, and excluding specific words or affixes from the analysis. You can also easily change the teaching order with drag and drop.
