THE SHORT VERSION
Paste. Compare. Carry on.
Paste your lists
Names, emails, product codes, or anything else. Put one item on each line, or paste a column from a spreadsheet.
Choose what counts as a match
Ignore capitalization or trim surrounding spaces. Blank lines are skipped, and duplicate items are counted once.
Take the results with you
Copy individual lists, or take a change brief showing additions and removals from A to B. Items keep their original order; shared items use List A’s spelling.
Nothing to upload. Nothing to sign up for.
Your lists are compared in this browser, never uploaded, saved to storage, or tucked into a link. Refresh the page and they’re gone. No ads. Optional Google Analytics and Statsig help us understand visits, tool use, and experiments only if you allow analytics. We never send list contents, clipboard contents, or individual items.
Analytics providers receive ordinary connection information, such as your IP address and browser, plus a random browser identifier and limited usage events. You can decline or change your choice with Analytics preferences at the bottom of the page. The tool works either way. Normal hosting requests still happen.
