    #11. Writer


    Like other apps that help you proofread your own content, the Writer checks for spelling, punctuation, and grammatical errors.

    However, Writer’s AI-driven copyediting takes it a step further to help you simplify your language for more precise writing, suggest sentence breaks to improve readability and check for language redundancies.

    Writer allows you to edit your rules and create your own style guide, so corrections are based on your own messaging and terminology. This helps writers throughout your company maintain consistent guideline adherence and write with a single voice—without having to constantly refer back to a style guide on a PDF.

    This is a valuable resource, even for veteran writers who are decades into their career.

    Writer is specifically crafted to meet the challenges of business writing, and it prioritizes your data security. It won’t store your data after processing for any reason. Once your content is “read,” it’s gone from Writer’s servers.

    Some of the key features of Writer are:

    • Writing support for any text on the web or in a document
    • Customizable rules so you can integrate your style guide
    • Data security
    • The ability to pause real-time suggestions to protect writers’ flow
    • Extensions for Chrome, Word, and Google Docs

    What is the difference between editing and proofreading?

    People often get confused and unsure about the difference between editing and proofreading.

    Editing needs an expert editor who makes changes and suggestions that improve the quality of your writing, especially language and expression.

    Proofreading, on the other hand, is the process of finding grammatical and punctuation errors and fixes them. Proofreading is important and cheaper than editing.

    In a nutshell, editing can magically enhance the quality of your writing, while proofreading ensures that it is error-free.

    Why Do You Need Proofreading Software?

    Error-free content is important especially when you’re running an online business. According to BBC, one entrepreneur said poor spelling is costing the UK internet businesses’ millions of pounds.

    On the other hand, TightPlease.co.uk found spelling errors decreased their conversions. Actually, they had made a small spelling mistake and misspelt the word “Tights” with the “Tihghts” and it was the reason they had less conversion. They noticed 80% conversion after fixing that spelling error.


    Furthermore, you might don’t get a job if you have spelling mistakes in your CV. Because 72.2% of recruiters said they disapproved the CVs that contain one or more spelling mistakes.

    Grammar Mistakes

    Things to Keep In Mind When Proofreading an Article

    The chances are high to make grammatical and spelling errors when English is not your first language.

    As a blogger, it’s your job to write error-free quality articles. Avoid silly English mistakes like using active/passive voice, tenses, punctuation, commas, etc.

    common grammar errors

    Once you finished with writing take a break and proofread your article after few hours or next day.

    Later when you’ll proofread your article your mind will be fresh and chances are new ideas can come to your mind that you can include in your article while correcting the error from your article.

    However, it helps but still, using free online proofreading tools you can find more mistakes and proofread your article fast.

    Key points to remember while proofreading an article:

    • Don’t proofread just after finishing the article. Take a break for a few hours or better proofread the next day
    • Get a quiet place when proofreading your article; so you don’t lose your concentration
    • Re-read your article aloud, this way you can find out if your articles sound right
    • Edit as soon as you find an error
    • Use proofreading tools to save your time

    For me, I prefer using both premium and free online proofreading tools.

    An online proofreading tool helps me find and fix the small errors I missed while writing.

    Remember, even if you are using best proofreading software to proofread your article make sure you read again to see if there are any errors left to fix, if found fix them before hitting the publish button.

    Though, there are plenty of professional free online proofreading tools you can use for a free grammar and punctuation check of your article.

    But, using the best grammar checker tool is always good. I recommend Grammarly proofreading software.

    Over to you!

    You already know the importance of an error-free article especially when you have an online business to run.

    Using these free online proofreading tools you can create grammatical-error-free content that will increase your conversion.

    However, these proofreading tools are a good way to start but nothing can beat human proofreader.

    The only problem is manual proofreading takes time while online proofreading tools proofread articles in minutes.

    You shouldn’t always rely on proofreading tools because these are just software that doesn’t understand human emotions.

    Let me know which one is your favorite free online proofreading tools in the above-mentioned tools.
