FAQ
Common questions
Do you upload my text anywhere?
No. Everything runs locally in your browser. Your text is not sent to a
server.
How does deduplication work?
Duplicates are removed by exact line match after the selected normalization
options are applied.
Can it keep the original order?
If you only deduplicate (without sorting), the first occurrence is kept and
order is preserved.
Does this tool work offline?
Yes. After the first load, the page can work offline thanks to browser
caching.
