Review punctuation in a draft.
A punctuation checker helps when a draft is clear in your head but the marks on the page send mixed signals: a missing apostrophe, a semicolon doing a comma’s job, or a quotation that never closes. This Punctuation Checker reviews the text you paste and returns a corrected version, along with a short explanation for each suggested change. It keeps your words in place and concentrates on the marks between them. Use it on essays, emails and reports, and treat every suggestion as a proposal you can accept or ignore.
You paste the text, the AI reviews every mark in context, and the output panel shows the corrected draft with notes. Nothing is applied to your original, so you can compare the two side by side and decide what to keep.
The review covers everyday punctuation, plus the sentence boundaries that punctuation is meant to show. A misplaced mark often signals a structure problem, so some notes point to the sentence rather than the symbol.
Input: “The teams report was due on Monday however nobody had seen the final figures, the manager asked: who has the file” A typical result adds the apostrophe in “team’s”, puts a semicolon before “however” and a comma after it, starts a new sentence at “The manager”, and ends with asked, “Who has the file?” Example only, not recorded output.
Most punctuation errors fall into a small handful of repeating patterns. Knowing them makes the suggestions easier to judge, and it helps you notice the same issue elsewhere in your writing.
Some punctuation is a matter of style rather than correctness: the serial comma, double or single quotation marks, spaced or closed em dashes, and whether periods sit inside closing quotes. If your school, publisher or company has a style guide, name its rules at the top of your text, and the review will apply them consistently instead of guessing.
Run it near the end of editing, once the content and wording are settled, so you are not fixing marks in sentences that will change later. It suits any text where small errors cost credibility.
It focuses on punctuation, but punctuation and sentence structure overlap, so it will point out run-ons and fragments that the marks reveal. For subject–verb agreement, tense and word choice, use the Grammar Checker, which reviews those areas in more depth.
Each suggested change comes with a brief reason, such as why a semicolon fits better than a comma between two complete clauses. Reading those notes is a practical way for students and second-language writers to learn the patterns that keep recurring in their own drafts.
It is meant to leave your words alone and adjust only the marks. A note may suggest splitting a very long sentence or adding a small joining word where punctuation alone cannot solve the problem, but the decision stays with you when you edit the result.
By default it follows the convention your text appears to use. American style usually puts periods and commas inside closing quotation marks, while British style often places them according to meaning. To fix one convention, say so before your text, for example “Use British punctuation”.
Yes. It handles essays, theses and journal manuscripts, including long sentences with lists and parenthetical asides. Say which style guide you follow, such as APA or Chicago. Check citations and reference lists against that guide yourself, since punctuation there follows detailed rules for each style.
It can review punctuation in the language of your draft, and conventions differ: French adds a space before some marks, and Spanish opens questions with ¿. Output can match the input language or be set to English, Simplified Chinese, Spanish, French or German.
Up to 50,000 characters per check, or a TXT, DOC or DOCX file up to 10 MiB. Shorter sections are easier to review, because you can hold each explanation next to the sentence it refers to.
