Spelling and Grammar Checker Tools: The Ultimate Guide

May 1 / Steve Bunyan
In this ultimate guide to spelling and grammar checker tools, we’ll explore why good spelling and grammar matter in business. We'll look at a number of important issues related to spelling and grammar, and I’ll introduce you to 20 different spelling and grammar tools to help you improve your writing and maintain a polished, professional image.

Good spelling and grammar

In business, good spelling and grammar matter. Without them, you can confuse people, harm your business, lose money, and damage your reputation.

English is not English

English isn’t just one language. It has many variations, including British, American, Australian and Indian. Knowing the differences helps avoid mix-ups and makes discussion easier.

The global market

Always remember, in our global market, English is just one of many languages. Good spelling and grammar matters in all languages to maintain clear communication and foster trust.

Avoiding common perils

Contrary to popular belief, jargon, acronyms and abbreviations make reading and understanding something harder, not easier. Jargon can alienate your audience and obscure your message. It might be commonplace in your industry, but not everyone is part of your industry. So avoid jargon at all costs and opt for clear, straightforward language instead.Avoid Acronyms for the same reasons. For example, don’t write ROAS, write, return on advertising spend because the former could mean different things to different people, where the latter is crystal clear to all. The same goes for abbreviations—just avoid them.

Deliberate misspellings

Despite what many self-appointed “marketing gurus” claim, misspelling words deliberately is always a bad idea. It will make your business appear unprofessional and damage your credibility.

Ampersands (&)

Ampersands are often misused. Using ampersands in brand names and headlines is fine, but just about everywhere else, it’s not. If you’re in any doubt about where to use them, don’t use ampersands at all.

Email deliverability

Poor spelling and grammar can have a negative and damaging effect on your email deliverability, because certain words, phrases, and misspellings can trigger spam filters in email marketing tools and email platforms like Gmail and Outlook.


Poor spelling and grammar can make you appear amateurish, uncaring, and untrustworthy, leading to lost leads, sales, and profits.

20 Spelling and grammar checker tools

Always remember to do your own research. Choose spelling and grammar checker tools that are a good fit for you, your business, and your budget.

Think multilingual

Multi-lingual spelling and grammar tools are essential in our global market, as they ensure clear communication and help avoid misunderstandings across different languages.


Plagiarism is a critical concern in the digital age. Several of the tools mentioned above offer plagiarism detection features, helping you maintain originality and avoid potential legal issues.

Authors are different

Book authors have unique needs with spelling and grammar. While Grammarly is a popular choice, it may not be the best fit for authors. ProWritingAid offers more comprehensive features tailored to the needs of authors, such as in-depth analysis and style improvement suggestions.

My Conclusions

In today’s business environment, good spelling and grammar are non-negotiable. They convey professionalism, attention to detail, and trustworthiness, and can make or break your success.

By understanding language variations, avoiding jargon, and using the right spelling and grammar checker tools, you can elevate your writing and maintain a polished, professional image. Whether you’re communicating with clients, partners, or colleagues, never underestimate the power of clear, error-free writing.
