About this tool

Word echoes happen when the same distinctive word appears twice within a few sentences — often invisible until a reader trips on it. AI drafts repeat nouns and verbs in close proximity because models lack human ear for rhythm. This word echo finder locates close repeats within a sliding window so you can vary vocabulary or restructure. Paste a paragraph or scene; detection runs in your browser.

What you can do

  • Sliding-window detection for close word repeats within paragraphs
  • Filters stop words and short tokens to surface meaningful echoes
  • Context snippets showing each echo pair for quick fixes
  • Adjustable window size (default 50 words) for tighter or looser scans
  • Catches AI habits like repeating a character name or setting noun twice in one beat
  • Fast enough to run line-by-line during revision
  • Complements word frequency finder for book-wide versus local repetition

Why manuscript analysis matters for fiction

Rule-based analyzers catch patterns human eyes skim past—especially in AI drafts where filter words, adverbs, and passive voice cluster predictably. Use metrics to prioritize revision, not to flatten your voice. Run a chapter first, fix the worst offenders, then scan the full manuscript.

How to use it

  1. Paste your prose into the text area.
  2. Click Analyze (default window: 50 words).
  3. Review the echo list with context snippets for each pair.
  4. Rephrase or synonym-swap flagged repeats that sound accidental.
  5. Re-scan after edits to confirm echoes are gone.

Tips for fiction authors

  • Echoes on distinctive words ("silhouette," "trembling") matter more than echoes on common verbs.
  • Deliberate repetition for rhythm ("He waited. Waited.") is fine — fix echoes that sound accidental or clunky.
  • AI often echoes the subject noun in back-to-back sentences. Restructure one sentence to break the pattern.
  • Read flagged lines aloud — your ear catches echoes the eye misses.
  • Run word echo finder on dialogue-heavy scenes where the same speech verb repeats in one exchange.

Common questions

What counts as an echo?

The same word (4+ letters, not a stop word) appearing again within the sliding window — usually within a paragraph.

Should I fix every echo?

No. Deliberate repetition for rhythm is fine. Fix echoes that sound accidental or clunky.

Is my text uploaded?

No. Word echo detection runs entirely in your browser on Entangled Text.

How is this different from word frequency?

Word frequency shows book-wide repetition. Echo finder catches the same word twice within a short local window.

Why do AI drafts produce echoes?

Models reuse recent tokens in close proximity. This tool makes those local repeats visible during polish.
