Quick Tool Overview

The Punctuation Checker finds the mechanical faults a machine can genuinely catch: spaces before commas, unbalanced brackets and quotes, doubled marks and sentences that never end. All of them are nearly invisible when you are reading your own text.

About the Punctuation Checker

Punctuation faults are mechanical, which makes them the one part of proofreading a machine can genuinely do well. A space before a comma, a missing closing bracket, two full stops in a row, a sentence that never ends — all of them are findable by rule, and all of them are close to invisible when you are reading your own text.

This finds them. Spacing around every mark is checked against the standard convention. Brackets and quotation marks are matched, so an unclosed pair is reported with its position. Doubled marks, missing sentence-final punctuation, spaces before punctuation, missing spaces after it, and inconsistent quotation styles are all flagged, with the option to fix everything in one pass.

Key features of the Punctuation Checker

Bracket and quote balancing

Nesting is tracked, so an unmatched pair is reported with where the mismatch starts.

Spacing conventions checked

No space before a comma, one space after — the faults pasted text carries in constantly.

Style convention reported

Whether your text follows British or American quote punctuation, rather than one being enforced.

One-pass fixing

Every mechanical fault can be corrected together, since none of them is a judgement call.

Honest about commas

The page says which comma rules a tool can genuinely check, and that placement is mostly judgement.

One. Every current style guide — Chicago, AP, APA and MLA — specifies a single space. The two-space rule comes from monospaced typewriters and has not been correct for decades.
