Paraphrase AI Detector&AI Paraphraser Detector to Spot Rewritten AI Content
Three-Way Paraphrase AI Signals You Can Explain
Lynote separates likely AI-written, AI-rewritten, and human-written signals so reviewers can understand how much of a draft may have been paraphrased. The goal is not a single mystery score; it is a clearer review path for essays, reports, articles, and compliance drafts.
Sentence Highlights for Rewritten AI Patterns
Paraphrased AI text often keeps the same structure while changing surface wording. Lynote highlights sentences that may still carry AI-like patterns, helping you review the exact lines that need a closer human edit.

Why Choose Our Paraphrase AI Detector?
Paraphrase Detection
Find AI content even if it’s been heavily reworded (using paraphrasing/spinning or even humanizing tools). These tools can make AI content less recognizable but they still leave artifacts which our system can detect.
Sentence Highlights
The tool also highlights sentences most likely AI-paraphrased to help reviewers identify potential trouble spots quicker.
Three-Way Scoring
It also provides more nuanced reporting that breaks down text into three categories: AI generated, mixed, and human written content (shown as percentages), helping expose partial edits or text which contains some AI traits despite being rewritten.
Paste or Upload
Paste text or upload .docx, .pdf, or .txt files to check essays, articles, or compliance documents for paraphrased AI patterns.
Actionable Reports
Actionable reports highlight which sentences may need manual review or editing. This guides users to focus on areas of mixed or uncertain paraphrased content in their documents.
No Text Stored
No account needed. Your text is never stored or used for AI model training—ideal for sensitive or unpublished paraphrased material.
