Keyword and tag cleanup
Combine research terms, tags, or labels, remove repeated words, and keep a stable source order for the final list.
Unique word list
Remove duplicate words from text
Turn keywords, tags, or vocabulary into one clean unique word list. Choose which occurrence to keep and how the complete result should be separated.

Create the unique word list you need
Whole words are matched with explicit capitalization and Latin accent rules. Punctuation marks word boundaries and is not added to the output.
More matching options
Ignore Latin accents
Treat café and cafe as the same word while preserving the retained spelling.
Apostrophes and hyphens stay inside words. Punctuation and emoji act as boundaries.
Words or text
Paste text or open one supported local file.

CSV is read as plain text. This tool does not parse columns, quoted fields, or multiline records.

When a unique word list is the useful result
Use this removal workflow when each whole word is an item and you want one retained occurrence in a new output.
Vocabulary and glossary preparation
Reduce collected vocabulary to one spelling per matched word before reviewing, teaching, or importing it elsewhere.
Flat word-list deduplication
Create newline-, space-, comma-, or custom-separated output when line-level or record-level deduplication is not the task.
Example: repeated terms become stable unique output
With capitalization and Latin accents ignored, and the first spelling retained, the generated list keeps the order of each first match.
Café, cafe, Apple, apple.
Banana, banana, mother-in-law.Café
Apple
banana
mother-in-lawPunctuation creates boundaries and is not copied into the generated word list.
How it works
- 1
Add words or text
Paste up to 1,000,000 characters or open one supported TXT, Markdown, or plain-text CSV file up to 1 MB.
- 2
Choose the matching and output rules
Keep the first or last spelling, choose capitalization and Latin accent matching, then select the output separator.
- 3
Review and export the complete list
Check the totals and repeated groups, then copy or download the complete result even when the on-page preview is shortened.
What the remover matches and returns
The settings change the generated list, not the source text in the input area.
Whole-word matching
Apostrophes and hyphens can stay inside words. Whitespace, punctuation, and emoji mark word boundaries.
First or last retained spelling
The selected occurrence supplies the spelling shown in output, while retained words remain in stable source order.
Explicit case and accent rules
Capitalization can be ignored independently. The accent option folds supported Latin diacritics without rewriting the retained spelling.
File, preview, and format limits
These boundaries keep the interactive browser workspace responsive and make the output behavior predictable.
- One local file, up to 1 MB
- TXT, Markdown, and plain-text CSV files are accepted. Input is capped at 1,000,000 characters.
- CSV is plain text
- The tool does not select columns or parse quoted fields, escaped delimiters, headers, or multiline records.
- Bounded on-page preview
- The result preview is limited to 20,000 characters and repeated-group chips to 100. Copy and Download still use the complete generated list.
Local processing and private text
Pasted text and supported file contents are read and processed in your browser. They are not uploaded to create the unique word list.
Production may collect limited page and workflow telemetry, but input, output, file names, file contents, and custom separators are not sent as Analytics fields.
Review the Privacy Policy for the complete telemetry and data-handling boundary.
Frequently asked questions
Does this remove repeated words from the original text?
No. It creates a separate unique word list. The source input remains available and unchanged in the input area.
Can I keep the last occurrence instead of the first?
Yes. Choose Keep the last spelling. The output uses that retained spelling and orders retained words by their positions in the source.
Are café and cafe treated as the same word?
Only when Ignore Latin accents is enabled. Capitalization matching is controlled by a separate option.
Can it parse a CSV column?
No. CSV is read as plain text. Extract the intended column with a reviewed CSV-aware tool before using this word-list workflow.
Does Copy include text hidden by the preview limit?
Yes. Copy and Download use the complete generated list; only the interactive preview is shortened.
