Duplicate Words in a List

Want to quickly find repeated words in a list, paragraph, or dataset? The Duplicate Words in a List tool shows you which words appear more than once and how many times instantly. Whether you’re reviewing content, analyzing keyword density, or debugging text output, this tool gives you a clean count of all duplicates, right in your browser.

Just paste your text, tweak the settings, and see repeated words sorted by frequency. No uploads, no logins, no delays.

How to Use:

• Paste or import your text into the Input Text box
• Use the Ignore case toggle if “Apple” and “apple” should be treated the same
• Enable Match whole words to avoid partial matches (like “in” matching “inside”)
• Set the Min word length to exclude short or filler terms (e.g. “a”, “an”, “on”)
• Results update live in the Duplicate Words box, showing repeated words and their count
• Click Copy to clipboard or Export to save your results as a file
• Click Clean to reprocess the list with the current settings

Live output flashes so you know when it’s updated everything works instantly without needing to reload.

What Duplicate Words in a List can do:

This tool is built for anyone who works with words, lists, or unstructured text. It’s especially useful for content editors, copywriters, SEO analysts, teachers, students, developers, and anyone who needs to analyze or clean up a batch of text.

Use it to:

• Identify overused words in blog posts, essays, or product descriptions
• Spot repeated tags, inputs, or entries in user-generated content
• Check for duplicate values in spreadsheet exports or CSV logs
• Test keyword density in SEO content or marketing copy
• Validate form entries or bullet lists for repeats
• Clean up data dumps, transcripts, or scraped text

You can set a minimum word length to avoid clutter from tiny words, or match case to be strict about how duplicates are counted. If you turn on whole word matching, you’ll avoid false positives like “in” matching “inside” or “input.” This is especially handy when working with code, config values, or interface text.

All processing happens live in your browser so your data never leaves your screen. It’s a fast, focused tool for one job: spotting what repeats, and how often.

Example:

Input:

apple banana apple orange banana fruit apple pie

Settings:

• Ignore case: On
• Whole words: On
• Min length: 2

Output:

apple: 3
banana: 2
