Free, without an account
Every visitor gets a generous number of free checks per day — no signup, no ads. Unlike the counters on this site (which run entirely in your browser), this tool sends your text to an AI model for processing. It is processed and immediately discarded: never stored, never logged, never used for training.
What does the punctuation checker fix?
Commas, periods, semicolons, colons, apostrophes, quotation marks, hyphens and dashes, question and exclamation marks — plus capitalization where a punctuation fix requires it. It deliberately leaves your word choice, grammar and tone alone; for full corrections use the Grammar Checker.
Is it a comma checker too?
Yes — comma placement is the most common fix: missing commas after introductory phrases, comma splices, serial commas and commas around clauses. Paste a sentence and it returns the corrected version instantly.
Is my text stored anywhere?
No. Your text is sent to the AI model, checked, and the corrected version comes back — processed, never stored. No copies, no logs, and your text is never used for training.
Does it work in languages other than English?
Yes — paste text in most major languages and it fixes that language's punctuation conventions (including Spanish inverted marks and French spacing rules).
