A quick tour of the issues CopyLint cleans up before they reach your customers.

Common mistakes CopyLint fixes automatically

CopyLint doesn’t try to rewrite your voice. It focuses on the boring, repeatable mistakes that slip through even the best review process. Here are a few of the biggest ones it catches by default.

1. Inconsistent product names

Problem: “Copylint editor”, “CopyLint editor”, “CopyLint Editor” all appear in the same deck.

CopyLint fix: the Branded names rule enforces a single, correct form everywhere – right down to spaces and hyphens.

2. Numbers that don’t scan

Problem: “We support three workspaces and 10000 projects for 5 teams.”

CopyLint fix: number rules spell out one to nine, add commas to large numbers, and convert “10+ users” into “more than 10 users”.

3. Ampersands (&) everywhere

Problem: “Sales & Support & Success” in body copy.

CopyLint fix: the Ampersands rule replaces stray & with “and”, while still allowing “R&D” or brand-approved names.

4. Mixed spelling (colour vs color)

Problem: half your pages use U.K. spelling, half use U.S., depending on who wrote them.

CopyLint fix: the Spelling rule standardises to U.S. or U.K. spelling across your site, so “optimise”, “colour”, and “organisation” all match your choice.

5. Messy punctuation and spacing

Problem: double spaces, commas before brackets, random hyphen spacing, three different ellipsis styles.

CopyLint fix: the Clean up and Humanize helpers quietly collapse double spaces, smooth out spacing around punctuation, and make sentences readable again.

You don’t have to remember any of this while you write. Turn the rules on once, and CopyLint will keep catching these patterns in drafts, pages, and campaigns – long after everyone’s forgotten the style guide.
