What does an AI proofreader do?

It performs the same job as a human proofreader's final pass: correcting grammar, spelling, punctuation, capitalization and consistency errors without rewriting your text. Unlike style-focused tools, a proofreader makes the smallest change that fixes each error.

AI proofreader vs grammar checker — what's the difference?

They overlap, but a proofreader is stricter about not touching style and adds document-level consistency checks (hyphenation, number style, serial commas, quotation marks). Use the grammar checker while drafting; use the proofreader as the last step before sending or publishing.

Is an AI proofreader good enough for academic writing?

For mechanics — grammar, punctuation, consistency — yes, and the Academic mode follows scholarly conventions. It doesn't replace a supervisor's feedback on argument or structure, and you should always verify field-specific terminology yourself.

Is this AI proofreader free?

Yes — free with no sign-up, up to 30,000 characters per pass, including the Track changes mode.

About this AI proofreader

Proofreading is the last line of defense before a text meets its reader — and the stage where tired eyes miss the most. This free AI proofreader does what a professional does on the final pass: it corrects every mechanical error (grammar, spelling, punctuation, capitalization, spacing) and enforces consistency in the details readers subconsciously notice, from serial commas to hyphenation.

What it deliberately doesn't do is rewrite you. Proofreading discipline means the smallest change that fixes the error, so your phrasing, rhythm and voice reach the reader intact. If you want deeper stylistic help, that's what the paragraph rewriter and sentence rewriter are for — before you proofread.

Use the Track changes mode to see every correction listed. It's the fastest way to catch the kind of mistakes that slip into final drafts: a duplicated word, an inconsistent capital, a comma that migrated during editing.
