Frequently Asked Questions
- What does the consecutive repeats mode do?
- It finds words repeated immediately in a row — "the the", "and and" — and collapses each run to a single word. The match is case-insensitive, so "The the" is also caught. This is the classic typo mode for prose.
- What does the all duplicates mode do?
- It treats your input as a word list — one word per line or separated by spaces — and keeps only the first occurrence of each word, removing every later repeat anywhere in the text. Use it to deduplicate keyword lists, vocabulary lists, or tags.
- Is the matching case-sensitive?
- No. Both modes match case-insensitively, so "Apple" and "apple" count as the same word. The first occurrence keeps its original capitalization.
- Which mode should I use for prose paragraphs?
- Consecutive repeats only. The all-duplicates mode removes every later repeat of common words like "the" and "a", which would destroy a sentence — it is meant for lists, not running text.
- Is my text sent to a server?
- No. The removal runs entirely in your browser — your text is never uploaded, stored, or shared.
