What is a list comparison tool?

Paste two lists (one item per line, from a spreadsheet column, a CSV export, or anywhere else) and this tool works out how they relate: which items are unique to each list, which appear in both, and the combined set of every distinct item.

It also handles duplicates within a single list: see which values repeat in list A or B, or grab either list back with duplicates removed, without needing a spreadsheet formula.
