    Reviews & Testimonials

    This writing tool was helpful for both creative writing and writing essays. It was like having an editor! It checked grammar, spelling, and helped find more elegant words/wording.
    There was a lot to like about the writing tool. My favorite part was that I didn't have to try and think about a synonym; it would do it for me.
    I loved how it combines synonyms, antonyms, definitions, suggestions, and grammar in one tool! It is much better than Grammarly.

    Frequently Asked Questions

    While free plagiarism checkers exist, it's important to consider the limited accuracy of those tools. Our AI-powered plagiarism checker compares your writing against billions of online sources, academic journals, and archives, ensuring all of your work is fresh (and legal). Even better, Grammar Coach provides high-quality grammar corrections for easier, faster, smarter writing.
    Grammar Coach checks billions of online sources, helping you avoid the most common types of plagiarism, such as:
    • Verbatim or direct plagiarism
    • Paraphrasing plagiarism
    • Patchwork or mosaic plagiarism
    • Improper citation and accidental plagiarism
    Here are a few types of plagiarism you should also watch out for:
    • Collusion or sharing
    • Paid or hired plagiarism
    • Self-plagiarism
    Although not technically illegal in most places, the consequences for committing plagiarism can be serious. If caught committing plagiarism, students may risk failing grades or expulsion, and professionals may be fired and/or ostracized from their professional community. So take the guess-work out of the equation, and let Grammar Coach ensure your work is plagiarism-free (and free of other writing errors, too).
    It’s simple! Access your Grammar Coach Premium account, select the purple quote icon in the panel at the top of the screen, and tap the “Check For Plagiarism” button to have your work instantly scanned against billions of sources. We’ll alert you if any of your work contains plagiarized content. A few additional steps you can take to avoid plagiarism include:
    • Learning the proper way to give credit to sources and to use citations.
    • Using direct quotes only when you really need to.
    • Summarizing an author's general point or argument using your own words.
