Frequently Asked Questions

Got questions? We've got answers

Is PunctuationWizard really free?

Yes — every tool is free with no usage limits, no accounts, and no paid tier. PunctuationWizard is MIT-licensed open source, developed in the open on GitHub.

Is my text uploaded anywhere?

No. Everything runs in your browser: the text you paste or drop is processed on your device and saved only in your browser's local storage so your work survives reloads. There is no backend and nothing ever leaves your machine.

What can it fix?

Spacing around marks, doubled punctuation, broken ellipses, straight-vs-curly quotes, apostrophes, every kind of dash, fullwidth and CJK punctuation, invisible characters like zero-width spaces, and more — each as a one-click action.

Can it remove em dashes from AI text?

Yes. The Dashes & Hyphens tool turns em dashes into commas or plain hyphens in one click, and the Unicode Cleaner normalizes smart quotes, ellipses, and invisible characters at the same time.

Do I need an account?

No. There are no accounts, no sign-ups, and no tracking of what you fix with the tools.

Does it work offline?

Yes. Once a tool page has loaded, it keeps working with no network connection — processing is entirely local.

How do I report a bug or request a tool?

Open an issue on the GitHub repository, or send a message through the contact form — both routes reach the same human.
