Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To remove duplicate lines, paste your text into the tool and it strips out repeated lines while keeping the first occurrence of each. Because it runs in your browser, your text stays on your device and is never uploaded.
The cleaned result is copyable and downloadable, and the tool reports how many duplicates it removed so you can confirm the cleanup did what you expected.
Many line-cleanup jobs still care about original order — a ranked list, a sequence of steps, or a log where order carries meaning. This tool keeps the first-seen copy of each line instead of sorting everything alphabetically.
That makes it safe to dedupe content where rearranging the lines would change the meaning, while still removing the repeats you do not want.
Short answers for the questions people usually have before trying a utility like this.

Yes. The tool counts and shows how many duplicate lines it removed from your text.
