01

Remove repeated lines or repeated sentences

02

Preserve the first occurrence and original order

03

Control case and whitespace comparison

Choose lines or sentences

Use Duplicate lines when every list item, URL, code, or log entry is on its own row. Use Duplicate sentences when repeated prose appears inside one paragraph or a single long line.

Why the original example looked unchanged

A line remover sees text between line breaks as one unit. If the same sentence appears twice on a single row, there is still only one line. Sentence mode separates that prose at sentence punctuation before checking for repeats.

Control how matches are detected

Turn off case sensitivity when “Apple” and “apple” should match. Normalize spaces to ignore leading, trailing, or repeated spaces. Empty rows can also be excluded from the result.

Order is preserved

The first occurrence stays in its original position and later matches are removed. The tool does not alphabetically sort your content, making it suitable for ordered exports and working lists.

Questions, answered

Frequently asked questions

Why was duplicate text on the same line not removed?

Line mode only compares content separated by line breaks. Choose sentence mode when repeated sentences appear inside one paragraph or long line.

Can I ignore capitalization when comparing text?

Yes. Turn off case-sensitive comparison to treat differently capitalized versions as the same item.

Does the tool change the order of my list?

No. It keeps the first occurrence of each item and preserves the original order.

Is my text uploaded?

No. Duplicate detection runs locally in your browser.
