The Text Repeater is a free online utility that duplicates any piece of text exactly as many times as you choose, with an optional separator between each copy. Type or paste a word, a tagline, a number or a whole paragraph, set how many times it should appear (from 1 up to 10,000), and pick how the copies are joined - directly one after another, with a space, a comma, a dash, or one copy on each line.
Repetition shows up everywhere once you look for it: keyword and hashtag stamps, watermarks on screenshots, padded strings and ASCII dividers, placeholder rows for tests, or spelling and typing drills for students. Doing any of that by hand means endless copying, pasting and counting mistakes. This tool turns it into a three-second job and counts every character, so your output is exactly as long as you expect - nothing more, nothing less.
It is written in plain JavaScript and runs entirely in your web browser. Your text never leaves your device, there is no account to create and nothing is stored anywhere, which makes it just as safe for confidential strings like tokens or internal phrases as for throwaway test data.
