Is there any website that checks your punctuation and grammar?

none that I know of, but there are plenty which will correct your spelling of "grammar."

Grammarly is a good site.

Grammarly is not free; it charges a fee for its services.

Yes, there are several websites that can help you check your punctuation and grammar. One popular website is Grammarly, which offers a free online writing assistant tool. To use Grammarly, you can visit their website or download their browser extension. Once installed, Grammarly will automatically check your writing for grammar, punctuation, spelling, and style errors as you type. It provides suggestions and explanations for corrections, helping you improve your writing.

Another website you can consider is ProWritingAid. It offers similar features to Grammarly, including grammar and punctuation checks, as well as style and structure analysis.

Both Grammarly and ProWritingAid offer free versions with some limitations, but they also provide premium subscription options that grant you access to more advanced features.

To use these websites, simply navigate to their respective websites and create an account if required. Then, you can either copy and paste your text into their editor or use it directly on supported platforms and web browsers.

It's worth noting that while these websites can be helpful, it's always important to have a good understanding of grammar and punctuation rules to enhance your writing skills. Additionally, manual proofreading and editing are crucial on top of using these tools to ensure the best possible results.
