Frequently asked questions
What is plagiarism?
The Oxford Dictionary defines plagiarism as: "the practice of taking someone else's work or ideas and passing them off as one's own." This includes copying someone else word-for-word without quotation marks, and citing a source incorrectly (or not at all).
How can I avoid plagiarism?
Whenever you use someone else's ideas, make sure you acknowledge them correctly in-text and in your reference list. If you're quoting the author directly, use quotation marks. If you're paraphrasing an author, make sure to write it in your own words and provide the relevant reference details. You can check if you've plagiarized accidentally by running your document through Outwrite's plagiarism checker.
Is the plagiarism checker free to use?
Outwrite's essential features, like grammar and spell checking, are available to all users for free. You'll need to upgrade to our Pro plan if you would like to use our plagiarism checker.
How many plagiarism checks do I get?
Pro users can access up to 50 plagiarism checks per month. If you would like more checks, contact us at help@outwrite.com
