Frequently Asked Questions

How are duplicates detected?

Lines are compared exactly, after trimming leading/trailing whitespace. Case and internal spacing matter.

Is there a limit on how much text I can paste?

No hard limit — everything runs locally in your browser, so very large lists may just take a moment longer.

Can I export only the duplicate lines?

Yes, switch “Values” to “Duplicates Only” before generating results or exporting.
