Data cleaning

Deduplicate keyword lists from different SEO tools to get a clean, non-redundant set ready for analysis.
Email & contact lists
Merge multiple contact exports and eliminate duplicate addresses before sending a campaign.
FAQ
Is my data sent to a server?
No. All processing happens entirely in your browser. Nothing is ever transmitted or stored.
What does "case sensitive" mean?
"Apple" and "apple" are treated as different entries when enabled. Disable it to treat them as the same.
Can I use a separator other than new line?
Yes — choose comma, semicolon, pipe (|) or space from the separator dropdown. Useful for CSV or inline lists.
Is there a limit on list size?
No hard limit — the tool runs in your browser and handles tens of thousands of lines instantly.
