Fun Facts

• The longest known repeated word in English literature is James Joyce's 'Bababadalgharaghtakamminarronnkonnbronntonnerronntuonnthunntrovarrhounawnskawntoohoohoordenenthurnuk' — a 100-letter word in Finnegans Wake (1939).
• In computing, the Unix 'yes' command repeats the letter 'y' indefinitely and was written by Ken Thompson — it's been part of Unix since 1973.
• Buffer overflow attacks historically exploited text repetition, sending thousands of repeated characters to overwrite memory — the Morris Worm of 1988 was one of the first.

FAQ

What separators are supported?

Newline, space, tab, empty, comma, or any custom string. The separator is inserted between repetitions, not at the start or end.

What's the max repeat count?

Soft cap at 10,000 to protect the browser. Beyond that, the repeated text usually isn't useful and you should use a generator script.

Can I repeat non-text?

The tool is string-focused. For binary repetition use a shell command (printf, dd). For images/videos use dedicated tools.

Is this useful for testing?

Common uses: stress-testing text-length limits, padding input to exactly N chars, generating long strings for DB field testing. Also for fun (100 emojis in a row).
