Remove Duplicate Lines for marketers

For marketers, Remove Duplicate Lines fills a gap most marketers run into daily: a small text task that doesn't justify opening a heavyweight editor, but that doing by hand is error-prone. Open the page, paste, do the thing, paste back.

Common marketers workflows

  • Quick checks before sending — counts, capitalization, formatting
  • Cleanup of pasted-in content from another source (Word, Slack, web pages)

Frequently asked questions

Can I trust the count for assignment / SEO purposes?

Remove Duplicate Lines matches the published Unicode standard. Cross-check against the tool of record (Word, your CMS) if that's what's being graded against.

Does Remove Duplicate Lines count characters with or without spaces?

Remove Duplicate Lines shows both counts simultaneously, so you can use whichever your target requires.

Is there a length limit?

Practically, several MB of text. Beyond that the browser starts to lag.

Will Remove Duplicate Lines work offline?

Yes — once the page loads, processing happens locally with no further network calls.
