Top 8 Free Punctuation Checker Tools & Correctors Online to Fix Errors

This updated article will find the best punctuation checker apps to improve your writing and be error-free!

I know you are looking for an excellent solution to check punctuation errors in your English text.

Don’t worry. You’re in the right place! 🙂

As humans, we make lots of mistakes. The inability to write perfect grammatical-error-free articles is just one of them.

However, we can get some help from tools to ease our workflow and get time-consuming and tedious tasks such as checking punctuation and grammar easily and instantly.

An improperly placed comma could result in changing the core of the article. That’s why using a pretty good comma checker for checking comma errors, a quotation marks checker for checking quotation-related errors, and an apostrophe checker for apostrophe-related mistakes is essential.

But they are a lot of tools, right? Comma placement, quotation, and apostrophe checker tools are a lot to handle. That’s why we need to use complete writing aid tools to complement mini-tasks such as checking punctuation, grammar, comma errors, periods, semicolons, etc.

Here are my eight best free punctuation checker tools online that I have used in the past and am currently using.

Free Online Punctuation Checker Tools

Grammarly puctuation checker

If you want a top-notch punctuation checker, I recommend Grammarly. It is not just only because I use it as my grammar checker tool to correct my English grammatical errors on blog posts but also because more than 4 million people trust this perfect tool.

Why Grammarly?

  • Robust Punctuation Corrector
  • Grammarly has an eye for checking over 250 grammatical mistakes
  • Enhance your vocabulary with Vocabulary builder
  • Plagiarism checker
  • Work everywhere (even on your Microsoft Word document editor)
  • Grammarly Keyboard app
  • And a lot more reasons… Learn more about Grammarly.

One of the most wanted features of any online punctuation checker is the ability to understand the affinity of each word. In other words, contextual spell check.

Easily correct punctuation errors

Luckily, Grammarly doesn’t become second for any premium or free punctuation corrector tool at this point. Grammarly has free and paid plans for people like you and businesses with teams. But, features such as Vocabulary enhancement, proper punctuation, and grammar checking are only available in paid plans.

I suggest you upgrade to the premium plan for at least one month to check if Grammarly is worth using for your needs. If you are looking for a good grammar tool for teams, read this Grammarly Business review to learn about Grammarly’s team features, pros, and cons.


ginger punctuation checker

Ginger is another punctuation checker. It comes with both free and paid plans. I have used this tool since 2012, and I can recommend this tool as well. If there is a good instant grammar checker tool that can compete with Grammarly, it is Ginger Software.

Why GingerSoftware?

  • Easy Punctuation Correction
  • Text to Speech
  • Translate (Currently, it supports over 40 different languages)
  • Personal Trainer

After The Deadline


Polish My Writing or After The Deadline is a free punctuation checker tool. But, it comes with amazing features. Grammatical, spelling, and style errors will be highlighted in different colors. (Grammar: green, Spelling: red, Stylish: blue) PolishMyWriting also provides active and passive voice suggestions. For blog posts, you should practice using Active voice rather than passive voice in most cases. (Doer should act in the subject.)

Even though you could not compare “Polish My Writing” with paid punctuation correctors like Grammarly, there are some awesome features you should be aware of, such as Polish My Writing’s license and supported platforms and services.

Paper Rater


PaperRater is another free punctuation correction tool. It can quickly identify grammar, spelling, punctuation, and style mistakes.

Spell Check 24

spellcheck24 is another free online punctuation checker tool. It works the same as other tools. But, its interface and the speed of grammar checking are impressive.

Here are a few key features of this proofreading tool.

Even though SpellCheck24 isn’t as popular as Grammarly and Ginger, still it’s a website to check punctuation and grammar errors for free.

It is another free proofreading tool. In fact, LanguageTool is an Open Source based grammatical checker tool. It is a multilingual proofreading tool. LangaugeTool comes under LGPL 2.1 or later licenses.

So, you can download it from its official website or Github and develop/alter the source code as you want. It also provides an extension for Mozilla Firefox that you can download over here.

Garretson Punctuation Checker

Gregory’s writing site is specially made to guide you in better English writing. Among his two writing tools, the English punctuation checker takes an important place.

It works the same as other tools. But, there is a limit to the word count that Garretson Punctuation Checker can analyze. It is 10,000 words at once. If your article includes more than 10,000 words, you can copy several paragraphs into the textbox and check for punctuation mistakes. After you finish correcting them, you can paste other sections as well.

Conclusion on Best Punctuation Checker Apps

Proper punctuation is very crucial for a meaningful article. We have seen funny punctuation examples like this many times.

Let’s eat grandma!
Let’s eat, grandma!

See the difference? One sentence states to eat grandmother while the other asks the grandmother to eat together. So, making sure every comma, colon, semicolon, period, decimal point, bracket, parenthesis, exclamation point, apostrophe, etc., are placed in proper places is very important.
