What is Duplicate Words in Text?
Transforms text so every word is immediately repeated — e.g. "hello world" becomes "hello hello world world". Choose the separator between the original and duplicate (space, comma, hyphen, or custom). Useful for emphasis, stutter speech effects, and fun text effects.
Common Use Cases
Creating stutter speech text effects, humour and comedy writing, testing text-processing pipelines with doubled tokens, creating emphasis patterns, and generating padding text.
How It Works
Splits text by whitespace, maps each word to "word + separator + word", and rejoins to form the output.
Frequently Asked Questions
What separator is used between the two copies?
A space by default. You can choose comma, hyphen, slash, or any custom separator.
Does it duplicate empty lines?
No — blank lines are passed through unchanged.
