Repeated Words / Echo Finder

Detect close-proximity repetition — the same word reused within a configurable window of N other words. An editor's tool for catching unintentional echoes.

When to use this

Use the repeated-words finder when editing fiction, essays, or any prose where close repetition reads as a stylistic mistake. Particularly powerful for technical writers who unconsciously reuse jargon.

How it compares

Word Frequency surfaces *what* is overused; Repeated Words surfaces *where* the repetition is too close. Use both when editing.

How it works

The finder records every position of every content word in the text, then surfaces pairs of occurrences that fall within a configurable window (default 50 words).

It excludes function words (the, of, and) by default since they're expected to repeat constantly.

Results are sorted by closest distance — the word with the tightest repetition is on top.

FAQs

What's a good window size?

Default 50 words catches paragraph-level repeats. Use 20 for sentence-level only; 100 for page-level.

Why are short words excluded?

Short words are usually function words (the, of, and) that repeat constantly. Min length 4 filters them out by default.

Is some repetition okay?

Yes — for emphasis, parallelism, or anaphora. The tool flags candidates; you decide.

Worked example

Input

"The garden was beautiful. The garden bloomed early. The garden smelled sweet."

Output

"garden" used 3 times — closest pair just 4 words apart.

"Garden" is repeated within a tight window. A copy editor would diversify: "the plot", "the beds", "the borders".

Common pitfalls

  • Some repetition is deliberate — for emphasis, parallelism, or anaphora.
  • Window size is a heuristic — 50 words catches paragraph-level repeats; 20 catches sentence-level only.
  • Function words ("the", "and") repeat constantly; keep the stopword filter on.
  • Domain terms ("API", "database") often must repeat in technical docs — adjust expectations.
