What makes your service better than the standard checkers in Word or Google Docs?

Standard editors use dictionary-based checking. Our service is powered by a sophisticated language model that understands context and meaning. This allows it to find errors in complex sentences, place commas correctly, and suggest better phrasing. Word is a dictionary; Punctuator.org is your personal AI proofreader.

How accurate are the corrections? Can I trust it with a thesis or an official document?

Accuracy is our top priority. For formal and business texts, the service is ideal, catching up to 98% of errors. However, for mission-critical documents (like contracts or dissertations), it should be used as an indispensable assistant rather than the final authority, as it cannot replace a professional's expert review.

I'm writing a social media post or a story. Will the service ruin my author's style?

The service aims to fix grammar, not kill creativity. It leaves slang and emojis untouched but will catch annoying typos. For writers, it acts as a proofreader, not a co-author—you can always ignore its suggestions if a deviation from the rules was a deliberate artistic choice. The final say is always with the author.

Does anyone see my texts? Can I check confidential documents?

Confidentiality is fundamental. Your texts are processed automatically; no human has access to them. Immediately after the check, all data is permanently deleted from our servers. We do not store, analyze, or share what you check with anyone.

How does the 'Check History' feature work if you don't store data?

The history is not stored on our servers but locally on your device, in your browser's memory (using localStorage technology). Only you have access to it, which combines convenience with complete privacy.

Is the service free? Are there any limits?

The service is completely free and has no limits on the number of daily checks. We are supported by advertising. To ensure fast performance, there is a limit on the amount of text per check, which is indicated below the input field.
