What the punctuation checker fixes
Punctuation does more than decorate a sentence. It separates ideas, signals pauses, shows possession, closes quotations, and helps readers understand the intended meaning.
Commas
Find missing, misplaced, or unnecessary commas in lists, introductory phrases, clauses, and direct address.
Periods and sentence breaks
Separate run-on text into readable sentences and add sentence-ending punctuation where the meaning supports it.
Apostrophes
Correct common apostrophe problems in contractions and possessive forms without changing the surrounding vocabulary.
Questions and emphasis
Add question marks and exclamation points when sentence structure and intent clearly call for them.
Quotation marks and brackets
Review opening and closing quotation marks, punctuation around dialogue, and paired punctuation marks.
Colons, semicolons, and dashes
Improve the connection between closely related ideas while avoiding punctuation that changes the original meaning.
How to check punctuation online
Use the checker as a final review for ordinary writing or switch to Transcript mode when the text comes from speech recognition.
Add your text
Type directly into the editor, paste an existing paragraph, or load the sample to see how the checker works.
Choose the right mode
Use Regular text for conservative corrections or Transcript mode to restore sentence boundaries in raw voice-to-text output.
Review and copy
Compare both versions, inspect highlighted changes, then copy the corrected plain text with its paragraphs preserved.
See the difference punctuation makes
A block of speech-to-text can contain the right words and still be difficult to scan. Sentence boundaries and commas turn it into usable writing.

After
I wanted to send you a quick update. The new onboarding flow is nearly ready. We still need to review the mobile version, fix two validation issues, and confirm the launch date with the support team.
The wording remains intact. The corrected version adds structure, punctuation, and necessary sentence-start capitalization.

Frequently asked questions
Direct answers about punctuation correction, transcripts, supported languages, and privacy.
What is a punctuation checker?
A punctuation checker reviews text for missing, misplaced, or unnecessary punctuation marks. It can help with commas, periods, apostrophes, quotation marks, question marks, colons, semicolons, dashes, and sentence boundaries.
Does the checker change my words?
The tool is designed to preserve the original wording and meaning. It focuses on punctuation and necessary sentence-start capitalization rather than paraphrasing or style rewriting.
Can it add punctuation to unpunctuated text and transcripts?
Yes. Transcript mode is intended for run-on paragraphs, meeting notes, interview transcripts, voice memos, dictated drafts, and other speech-to-text output. It identifies likely sentence boundaries and adds punctuation based on context.
Which punctuation marks can it check?
It can review commas, periods, apostrophes, quotation marks, question marks, exclamation points, colons, semicolons, dashes, hyphens, brackets, and related sentence punctuation.
Is this different from a grammar checker?
Yes. A grammar checker may change sentence structure or vocabulary. This punctuation checker has a narrower task: improve punctuation and sentence boundaries while preserving the wording.
Which languages are supported?
The tool is designed for English, Spanish, French, German, Portuguese, Italian, Dutch, Turkish, Persian, and Arabic. English users can choose US or UK conventions, and Auto-detect can identify the dominant language.
Is my text saved?
The tool is designed not to save submitted text in a VoiceDash history or database. Text must still be processed to generate the result, so avoid entering passwords, financial details, medical records, or other highly sensitive information.
Write faster without fixing punctuation afterward
VoiceDash turns natural speech into polished text directly where you write.
