What does the List Comparer do?

It compares two line-based lists and shows four sections: items only in list A, items only in list B, items in both lists, and a combined unique merge of both.

Can the comparison ignore case?

Yes. Turn on the ignore case toggle and Apple and apple are treated as the same item.

Are duplicates inside one list removed?

For comparison purposes each list is treated as a set of unique items, so repeated lines in the same list do not inflate the results.

Can I copy the results?

Yes. Each of the four sections has its own copy button, so you can paste just the differences or just the overlap wherever you need them.

What is the combined unique list?

It is the union of both lists with duplicates removed, preserving the order items first appear in.

Is my data uploaded anywhere?

No. The comparison runs locally in your browser, so it is safe for private lists.

About this tool

IconVault's List Comparer finds the difference between two line-based lists instantly. Paste list A and list B to see four results: only in List A, only in List B, in both lists, and a combined unique merge, with live counts and per-section copy buttons, so deduping email lists, keyword sets or ID lists takes seconds.

Options include trim whitespace and ignore case for forgiving comparisons. Comparison is live as you type, runs fully in your browser with nothing uploaded, and it is free to try (heavy repeated use may ask for Pro).
