    • Grammarly Premium includes unlimited plagiarism checks.
    • The versatility of many formats. It’s accessible as a web-based online grammar checker tool, a web browser extension, a desktop program, a Microsoft Word add-on, or a mobile keyboard.

    Grammarly Review

    The Grammarly app might be a little pushy when it comes to recommending faults. Grammarly, for example, adores commas, even when they disrupt the flow of a text.

    Grammarly’s free edition will spot errors and provide a rudimentary grammatical check. Advanced problems such as plagiarism and passive voice detection in the premium edition, giving feedback to help you improve your writing.

    Grammarly is a beautiful pick for improving your writing abilities and keeping your work error-free.

    2. Ginger

    The free tool has a character restriction of 350 characters. If you sign up for the Ginger grammar checker, you can acquire a much more powerful Google Chrome extension for free. This will open the Ginger Writer software, which will allow you to copy and paste your text to check for problems.

    Ginger Review

    The free version only provides little error feedback. Ginger does not work with Mac OS X or Google Docs.

    To see an analysis of your errors or for more advanced grammar checks, you’ll need to upgrade to the premium edition. 

    If English is your second language, then Ginger is a great option.
