Extract unique words — a clean list of every distinct word

How to use the Unique Word Extractor

1. Paste your text into Your text.
2. Pick an Order: First appearance, A → Z, Most frequent first, or Longest first.
3. Keep Ignore case ticked to merge “The” and “the”, or untick it to keep them apart.
4. Choose an Output style: One per line, Comma-separated or Space-separated.
5. Check the Unique words and Total words counts, then copy the list.

What it does and when to use it

The tool removes repetition at the word level and hands you the vocabulary of a text. Typical jobs:

• Building a word list for language study from a song, article or chapter, sorted A to Z.
• Collecting terms for a glossary or index from a manual.
• Making tag or keyword lists from product descriptions, comma-separated and ready to paste.
• Checking spelling variants, with Ignore case off, to catch “email” and “Email” used side by side.

The two counts give a quick sense of variety. A 1,000-word text that holds only 250 distinct words repeats itself a lot. For the full set of counts and averages, open Text Statistics.

This tool works on single words. To remove repeated lines from a list, use Remove Duplicate Lines. To delete repeated words while keeping the sentence, use Remove Duplicate Words.

How it works

The text is split into words: runs of letters and digits, which may contain an apostrophe or hyphen in the middle. Each word is lowercased when Ignore case is on. The tool records each new word the first time it appears and counts later copies. The order you chose is then applied, and the list is joined with a new line, a comma and space, or a single space. Nothing leaves your browser.

Worked examples

All three use the text “red green Red blue green red”, which has 6 words.

Default settings. Ignore case merges “Red” into “red”. The result is Unique words: 3 and Total words: 6, listed as red, green, blue in order of first appearance.

Case kept, sorted, commas. With Ignore case off, Order A → Z and Comma-separated output, “Red” is its own entry: blue, green, red, Red. Unique words is now 4.

Most frequent first. With Ignore case on and Space-separated output, red (3 times) comes before green (2) and blue (1): red green blue.

Limits and tips

• Word forms are not merged: “child” and “children” are two entries.
• Sorting A → Z follows your browser’s language rules, so accented letters sort next to their plain forms.
• Clean pasted PDF or web text with Remove Accents first if you want “café” and “cafe” to merge.
