Grammarly permits a 7 day free trial, but you have to purchase it on credit card and cancel before the 7 days are up. The site is focused on writing and English grammar checking and proofreading, and includes a plagiarism testing component. There is only a window for pasting in text, and only one test can be done at a time. It found about 30% of the plagiarism, but the reports could not be stored. We wrote an email to complain, and received a reply that they are working on it – we never heard back from them.
