Paste your text into the input box and click "Remove Duplicates." The tool scans every line, keeps the first occurrence of each unique line, and removes all subsequent duplicates. You can toggle case sensitivity (so "Hello" and "hello" can be treated as the same) and whitespace trimming (to ignore leading/trailing spaces). The status shows how many duplicate lines were removed.
