List comparison
Compare Two Lists
Compare two lists in your browser to find common items, List A-only values, List B-only values, symmetric differences, and unique values.
List cleanup
Remove Duplicate Lines
Remove duplicate lines locally in your browser, preserve the first or last occurrence, normalize whitespace, sort, copy, or download the result.
Ordering utility
Sort Lines
Sort pasted lines A-Z, Z-A, numerically, or by length in your browser, with optional trimming, blank-line removal, and deduplication.
One reusable processing engine
All three tools share deterministic parsing, normalization, deduplication, natural sorting, intersection, difference, symmetric-difference, counting, copying, and text-download functions.
