One of our Juniors at Ransom Everglades just showed me a new web tool that he has been developing, Vocabulist. It allows you to upload a PDF, Word, or Text Document of Vocabulary Words, defines them using Merriam-Webster, and then generates a fully defined list of terms that you can use to study. It will even let you export to Quizlet. This is a great way to quickly generate term definitions for study or a quick Quiz.
The App is still in development, so please send your feedback and suggestions here.
