When you’ve written copy and you need to check its grammar, sometimes all it needs is a quick grammar check. Checking your grammar ensures that it’s more correct than it would be without any editing, so using a free grammar checker is quick with no downside.

Of course, a full copy edit is important as well. But if you don’t have that time or budget then do what you can with what you have and use our free grammar checker, powered by Perfect Tense.

How To Check Your Grammar For Free

Step 1: Paste Your Text

Copy your text (CMD+C) and paste it (CMD+V) into the free grammar checker box above.

Step 2: Submit to OpenAI

We leverage OpenAI to correct your grammar and punctuation on the fly. Paste your text, enter your email, and submit.

Step 3: Get Perfected Text

Your corrected text will be sent to the email you provide. Copy, paste, publish!
