When your words are about to finish, you can always reload it or update your plan from one to another easily. Unlike other costly ineffective plagiarism tools, oxphrase has simple pricing scheme that enables you to choose the exact amount of words that meets your requirement, for example, 15,000 words for a research paper, 30,000 for a book, or thesis.
