How many words do you write in a day? Between messages, emails, documents, and assignments, you probably type around 5,000 words—or maybe even more! But how many words do you misspell? Most of us don’t keep track of these errors since autocorrect (like T9) often fixes them. However, it doesn’t catch everything, such as typos, slang, or word interchanges. This can lead to awkward sentences like:
“So sorry I couldnt hand in everything in time. Smth urgent came up. I will make sure to take care of the metter some time in teh future.”
Here, simple typos change the clarity and professionalism of the message. In these situations, a quality spell-checker becomes invaluable. Luckily, there are many services available, and choosing the best one can make your writing clearer and more effective.
We decided to make this process easier by testing 10 popular spell-checking solutions. Here is a detailed guide to help you find the best tool for your needs.

How We Tested Grammar Checkers
Our team used a thorough, holistic approach to examine these tools. We looked at user experience, features, and pricing, as well as their practical application. To test these spell checkers, we prepared three different texts:
- A brief email to a professor requesting a deadline extension.
- A personal statement essay for a college application.
- An introductory paragraph of a research paper in Business Management.
These texts were intentionally filled with mistakes in punctuation, spelling, grammar, word usage, and sentence structure. We ran all three through each grammar checker to see how they performed. Below are the results.
