— no items —

💡 Paste a list in each box (one item per line). Only in A = items missing from B · In both = the overlap · Only in B = items missing from A · All (unique) = combined, de-duplicated. Everything runs in your browser.

The "All (unique)" view merges both lists and removes duplicates in one step.

Use "Ignore case" to treat differently-cased duplicates as one.

📋

Copy the merged list straight into your spreadsheet or tool.
