Text Repetition Detector & Rewriter
Advanced TF-IDF & AI Semantic analysis to detect sophisticated text transformations.
What is Text Repeats Detector
Check a text for internal repetition or compare two versions for semantic similarity. Single mode flags repeated fragments with a score; dual mode gives a visual diff, and the AI rewrite produces a polished variant via the site AI service.
How to use Text Repeats Detector
- Choose single-text or dual-comparison mode and paste your text
- Run the analysis (or deep analysis) to see repeated fragments and the score
- Optionally run the AI rewrite for a cleaner version
Frequently asked questions
Is the analysis done locally?
Basic repetition scanning runs in the browser, but the semantic similarity and AI rewrite features call the site AI service, so text is sent for those steps.
What does the similarity score mean?
It estimates semantic overlap between the two texts — higher means more alike, even when wording differs.
Can the AI rewrite be used as-is?
The rewrite restructures sentences in your chosen style, but it can shift details — proofread before publishing so "de-duplicated" doesn't become "de-meaninged".
