Remove Duplicate Words
Remove repeated words from your text, keeping the first of each.
Strip out repeated words
Duplicate words creep into text from careless editing, merged notes, or pasted lists — "the the", a keyword repeated, or the same tag entered twice. This tool removes repeats and keeps the first occurrence of each word, so your text reads cleanly without you hunting for every duplicate.
It is useful for tidying tag lists, deduplicating keyword sets, and catching the accidental double word that a spell-checker often misses.
How matching works and privacy
It compares words after trimming, so "Apple" and "apple" may be treated as distinct depending on case — normalise case first if you want them merged. Everything runs in your browser and the text is never uploaded.
Frequently Asked Questions
Which occurrence does it keep?
The first appearance of each word is kept and later repeats are removed, preserving your original order.
Is it case-sensitive?
Words are compared as written, so "Apple" and "apple" can be treated separately. Lowercase the text first to merge them.
Is my text uploaded?
No. Deduplication runs in your browser and nothing is sent to a server.
