How Text Redundancy Finder works
- Paste your text — a deliberately padded sample paragraph is pre-loaded and analysed immediately.
- A pattern match finds any word immediately followed by itself ("the the"), which usually slips in during editing.
- Every overlapping sequence of the chosen phrase length (3 to 8 words, 4 by default) is counted; any sequence occurring more than once is flagged as a duplicate phrase.
- The text is checked against a list of common wordy filler phrases (like "in order to" or "due to the fact that") that a shorter word usually replaces cleanly.
- All three categories are colour-coded directly in the highlighted text, and listed individually below it — copy the whole report as plain text with one click.
None of this is a grammar or style AI — it's straightforward pattern matching over your exact words, which makes the results predictable and exactly reproducible on the same text.
FAQ
What counts as a "duplicate phrase"?
The tool breaks your text into overlapping word sequences — 4 words by default, adjustable from 3 to 8 — and flags any sequence that appears more than once, word-for-word. The floor is set at 3 rather than 2, because 2-word combinations like "in the" recur constantly in normal prose and would flood the results with noise; 3 and up reliably catch an accidentally repeated fragment instead.
Where does the filler-phrase list come from?
It's a fixed list of commonly flagged wordy constructions — things like "in order to," "due to the fact that," and "at this point in time" — phrases that style guides and editors routinely suggest cutting because a shorter word or nothing at all says the same thing.
Does flagging a phrase mean I have to remove it?
No — this is a highlighting tool, not an automatic rewriter. Some flagged phrases read fine in context; the point is to surface every candidate so you can judge each one, not to enforce a rule.
Is matching case-sensitive?
By default, no — "Apple" and "apple" count as the same word so you catch every repeat regardless of capitalization. Turn on "Case-sensitive matching" if you specifically want proper nouns and mid-sentence words treated as different.
Can I save or share the results?
Yes — "Copy report" copies a plain-text summary of the counts and every flagged issue to your clipboard, ready to paste into an email, a doc, or an editing note.
