But doesn’t proofreading and polishing your writing seem like extra work?

Hell yeah, me too!

In this article, I’ll share a list of my top 10 best proofreading software and tools that will check your writing for grammar and spelling errors, suggest you any missing punctuation and polish your copy for free!

Top 10 Best Online Proofreading Software & Tools for 2021

1 Grammarly’s Online Proofreading Software

Grammarly online proofreader tool

Grammarly is one of the world’s best proofreading tools you can find.

It comes with a sleek online editing interface (where you can write directly or upload a document to proofread it), an add-in for MS Word (proofreading tool in MS Word) and free browser extension (your personal proofreader on social media, emails, and WordPress)

Grammarly is an online proofreader tool, so you can use it across all any platform you write, may that be a blog post, social media updates, or a business email, Grammarly proofreads all. Check out my hands-on Grammarly review here.

You can also use Grammarly’s writing editor online for free (click here to get a free Grammarly account) and then directly write on their inbuilt editor right from your browser.

It detects over 400+ types of grammatical errors, contextual spelling mistakes (ones that your favorite word processor often skips), and helps you with the correct punctuation.

If you have already written a paper or article, you can simply copy-paste or upload the document and let Grammarly do the proofreading for you.

What I liked about Grammarly is that it detects and proofreads complex language mistakes like subject-verb agreement, active and passive voice checker, or writing style.

For example, here’s a sample document that I threw at Grammarly to test its proofreading capacity.

Did you see how it suggests corrections in your writing and also has an education twist to help you improve it?

You can also set Grammarly to proofread your document based on your language preference (American English, British English, Canadian English & Australian English) to get customized suggestions further.

Not only that,

You can also use the Goals feature to check your copy based on your audiences like their potential (expert, knowledgeable etc.), tone (formal, informal, neutral etc.) and domain like academic, general, creative, business copy etc.).

This goals feature comes handy because unlike other proofreader tools out there, Grammarly helps you detect mistakes and offer better word suggestions based on your audience and writing style.

Grammarly Performance report

No proofreading service is complete if it doesn’t offer you a performance report. These reports not only help you measure your writing skills (and improve them over time with a spirit of competence) but also helps you rate the work of freelance writers and students).

Pro Tip: If you have an online proofreading job or offer proofreading services, you can generate these PDF performance reports for clients to make your work more professional.

The premium version of Grammarly comes with added benefits like better word choice, checking your content for more grammatical errors, and a plagiarism checker.

Grammarly’s online proofreader tool also provides one of the best plagiarism checker software you can even find. It checks your content against a database of over 8 billion web pages that detects any traces of copied content (I’ve tried it, and it works wonders!). Apart from that, Grammarly’s citation generator helps you generate citations in APA, MLA, and Chicago.

Grammarly is also available with business plans for teams (trusted by Cisco, Dell etc.) and as Grammarly EDU (trusted by The University of Phoenix, Illinois, and leading libraries, to name a few).

Grammarly also offers a free chrome extension that proofreads, corrects, and makes sure everything you write on chrome (emails, social media, blog posts) error-free.  (Add to Chrome for free)

On a side note, if you’re looking for free proofreading apps on mobile, Grammarly’s Android and iOS apps have got you covered.

2 ProWritingAid‘s Editor and Proofreading Tool

If you’re looking for the best proofreading software for writers, it is this!

I’ve covered ProWritingAid before in this blog. It’s one of the best grammar and spell checker tools you can find online.

Unlike other writing tools, ProWritingAid offers more proofreading services or features:

  1. Editing your content: (includes grammar and spell corrections, proofreading, punctuation checking, style suggestions, and other advanced editing tools like tense shifter).
  2. Style checker, clichés, sentence structure, readability measures, repeated words, dialogue checker, pacing, checking your transition words, acronym, and homonym checker are few of the features offered by ProWritingAid that makes it a perfect writing & editing tool for authors and editors.
  3. Checking for plagiarized content: Even though you don’t copy, there might be traces of unintentional plagiarism (errors in a proper citation, some content influenced by something you read some time ago etc.) that could ruin the game for your paper. 

I highly recommend you to check out my ProWritingAid review because the range of proofreading that this tool does is insane! I’ve listed over 20 different types of tests you can do with it (and honestly, I left it at 20 because I simply couldn’t include everything it does!).

ProWritingAid is the only proofreader software in this list that supports Google docs (along with other options like using it online, with MS Word, as a standalone app etc.) ,which is an added bonus if you do a lot of writing on Google docs (like me!).

UPDATE: Grammarly now supports Google docs!

If you’re looking for a proofreading software for Scrivener, PWA has got your back covered. 

ProWritingAid works for everyone looking for an easy to use yet accurate proofreading tool but works as the best editing, and proofreading tool for authors, storytellers and potential writers.

ProWritingAid’s style checker detects such errors that are next to impossible for the human eye to check, may that be passive voice, use of adverbs or any other readability element like sticky sentences or maintaining a safe glue index.

Having said that…

ProWritingAid, like Grammarly, can be used to preset a style based on what type of content you write. You can set it to check your copy based on business, web, creative, or any other purpose. This feature gives a better scope for proofreading your document based on the industry you’re writing.

SPECIAL OFFER: We’ve partnered with ProWritingAid to offer DigitalGYD readers with special ProWritingAid discount coupons. Simply, go to use the code “GYD1925” to claim your exclusive ProWritingAid discount coupon and save a whopping 25% OFF.

My Verdict: ProWritingAid is truly a writers’ tool. And apart from creative writers, ProWritingAid as a writing assistant or proofreader for anyone in general, is a tough competition to Grammarly. So, technically it is not #2 on this list; both Grammarly and ProWritingAid are #1 for me.

3 WhiteSmoke’s Proofreading Software

While Whitesmoke doesn’t stand a chance in front of Grammarly or ProWritingAid to that matter, it is the best you can get if you don’t want Grammarly or ProWritingAid for some reason.

Hence the position #3 on our list.

WhiteSmoke offers all the essay correction, and writing suggestions based on natural language processing or NLP and according to context. It’s a great proofreading software for dyslexia.

If you’re looking for the best website proofreading software, WhiteSmoke’s one-click instant proofreading feature has got you covered.

  1. Hi, Can you please let me know of the TOP #1 Proofreading software which contains top-notch information about everything?
