What does the duplicate counter show?
Every unique line from your list alongside the number of times it appears, sorted by frequency so the most common entries sit at the top.
Can it find duplicates in a keyword list?
Yes — it is ideal for SEO keyword lists, showing which phrases repeat and how often, so you can consolidate cannibalizing keywords.
Does it sort by count or alphabetically?
Results are sorted by occurrence count (highest first), making it easy to spot dominant entries at a glance.
Is my list uploaded anywhere?
No. All counting happens in your browser, so your data never leaves your device.
