Remove Duplicate Lines sits next to your editor and counts in real time so you don't accidentally publish a title that gets cut off mid-sentence.

Frequently asked questions
Does Remove Duplicate Lines save my text?
No. Remove Duplicate Lines processes everything in your browser; nothing is uploaded or stored.
Is there a length limit?
Practically, several MB of text. Beyond that the browser starts to lag.
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.
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.
