What the punctuation checker does

  • Fixes commas and other marks

    Fixes commas and other marks

    Commas in compound and complex sentences, after introductory phrases and around direct address; dashes, colons, semicolons and quotation marks.

  • Explains every correction

    Explains every correction

    Ask for the rule behind any comma it added or removed, so you remember it and get it right next time.

  • Checks spelling too

    Checks spelling too

    Ask it to fix typos and spelling at the same time, or only to point them out without changing your text.

  • English and other languages

    English and other languages

    Punctuation rules differ between languages, and the AI follows the rules of the language your text is written in.

How to check punctuation in your text

  • Step 1. Paste your text

    Paste your text into the message box. Long texts are easier to check in parts, one paragraph at a time.

  • Step 2. Get the corrected version

    The AI returns your text with the punctuation fixed. Ask it to highlight the changes if you want to see exactly what it corrected.

  • Step 3. Ask about anything unclear

    If you are unsure about a comma, ask which rule it follows. In creative writing, the final call is yours.

Who it is for

  • Students

    Check an essay or paper before you hand it in, and understand the rules while you are at it.

  • Writers and editors

    Proofread an article or post quickly before it goes live.

  • Professionals

    Send emails, reports and announcements without punctuation mistakes.

  • English learners

    Check the punctuation in your English text and see how it differs from your own language.

interested

  • Punctuation checker online

    Paste your text into the message box and the AI returns it with the punctuation fixed. It works in the browser on a computer or phone, with nothing to install.

  • Comma checker

    If you only want commas checked, say so: "check only the commas and leave everything else as it is". The AI marks missing and unnecessary commas and explains why.

  • Where to put commas

    Commas most often go missing in long sentences, after introductory phrases and around extra information. Ask for an explanation of exactly these spots and the rule sticks faster.

  • Punctuation and spelling check

    You can check punctuation and spelling in one go. Ask for a list of the mistakes first and then the corrected text, so it is easy to see what changed.

  • Does this sentence need a comma

    If you are unsure about one spot, you don't need to paste the whole text: type the sentence and ask whether it needs a comma and why.

  • Punctuate my text automatically

    The AI adds punctuation automatically, but in creative writing punctuation sometimes depends on meaning and rhythm. Review those spots and decide for yourself.

  • Punctuate this sentence for me

    For a single sentence, type it in full and ask for the punctuation with an explanation. It is a handy way to work through a tricky case before a test or exam.
