Ever found yourself in an embarrassing situation like this?

You write something and hit ‘send,’ only to later discover it’s full of punctuation mistakes. Super annoying, right? Missed commas, off periods, and awkward dashes – they’re easy to overlook.

Correct punctuation in your writing matters! It makes your writing clear and easy to follow. Without proper punctuation, your readers will end up being confused, and they may never read anything written by you again. And punctuation marks are more than just making your writing smoother; they connect with the emotions of your readers. They help your readers know how to react when they encounter an exclamation mark or what it means when they see a comma.

GrammarLookup’s free punctuation checker instantly catches all punctuation errors 

This free grammar checker helps you catch and correct common punctuation errors, making writing a lot less stressful. 


Often the simplest punctuation, but a misplaced period can change the meaning entirely. Is your sentence really complete?

Question Marks?

Sometimes it’s clear, sometimes it’s not? When adding a question within a statement, the placement can be tricky.


It’s all about ownership: the dog’s bone, two weeks’ notice. But where exactly does the apostrophe go?


The most used (and often misused) punctuation in English. A comma can change the rhythm and meaning of a sentence, so where should it go?

Colons & Semi Colons 

Colons introduce, semicolons connect. What to use when?

Exclamation Points!

It’s not just what you say, but how you say it! Are you using exclamation points for impact or overdoing it?

Hyphens and Dashes

Short and long — each has its place. Are you confusing hyphens with dashes?


Often used for “and/or” situations, dates, and fractions – but are you using slashes correctly in every context?


Perfect for showing hesitation or trailing off… but are you using too many or too few dots?

Quotation Marks

“Quotation marks” frame direct speech and titles. Are yours in the right place?
