Online grammar and punctuation checkers are helpful tools to help you come across more professionally with your writing. Whether you’re starting a blog, writing a professional email, blog post, long-form article, or e-book, it’s important to avoid spelling errors, grammatical errors and silly mistakes. There are now quite a few resources that can help you in this area. In this guide, we’ll be taking a close look at some of the leading grammar checker tools, noting their pros and cons.
When using any such tool, keep in mind that none of them are perfect. Nor can they do the writing for you. It’s still up to you to create engaging content for your audience. They can, however, help you turn in error-free work that helps establish your credentials as a true professional.
What To Look For When Choosing A Grammar Checking Tool
1. Carefully consider your needs and make sure you find a tool that has the features that you require. Some tools, for example, only address spelling errors and don’t correct grammar.
2. Consider the price but also keep in mind that an effective grammar checker can increase your income in the long-term by helping you create superior content.
3. You may want to write free form without the grammar checker for your first draft. Many tools have distracting effects such as red lines that can interfere with your concentration. You can do the correcting later. Now let’s get to the reviews of some of the top grammar checkers currently available.
Here’s My List Of The Best Grammar Checker Tools On The Web
Grammarly is probably the best-known English grammar checker of all as the company advertises quite aggressively. There’s both a free and paid version. You can download the free Chrome extension to get an idea of how it works. The paid version is fairly costly, over $130 per year. They do, however, run frequent sales and you may be able to find promo codes to lower the cost.
Grammar.ly is free to use, but to unlock all the great features it has to offer, you will need to pay. There are three plans. If you do want to go premium, then I suggest paying up front for the whole year. This will save you a massive $220.
- Checks spelling and grammar errors quite comprehensively. Even the free version corrects all “critical” issues while the paid version also suggests ways to improve style.

- Helps to improve your writing skills and sentence structure.
- Not perfect. This is true for any tool, of course. Grammarly will sometimes make incorrect suggestions such as telling you to insert an article where none is needed.
- The paid version is a bit expensive. Is it worth it? Jury is still out on that verdict.
