Line Deduper

This line deduper is useful when removing repeated lines from copied lists, exports, notes, wordlists, or cleanup tasks where duplicated entries make the result harder to work with.

Common mistakes include forgetting that spacing and capitalization differences may prevent lines from counting as exact duplicates, or deduping lists before reviewing whether repeated lines had intentional meaning.

This fits into text cleanup, wordlist preparation, note consolidation, export normalization, spreadsheet copy cleanup, and browser-based utility workflows where faster line cleanup is useful.
