AI Detector for QuillBot Humanized Copy
Why Detect Humanized AI Copy
QuillBot Humanizer Signals
Review writing signals that may remain after copy has been processed by QuillBot Humanizer or a similar humanizing tool. Lynote checks visible text patterns without claiming access to QuillBot history.
Humanized Sentence Highlights
See which sentences still read as AI-written, over-smoothed, or heavily humanized. This helps reviewers focus on the lines most likely to show QuillBot-style rewriting signals.
AI Mixed Human Scores
Get a probability report showing AI-generated, mixed, and human-written percentages. The score helps you judge whether humanized copy still carries detectable AI structure after rewriting.
Paste or Upload Copy
Paste suspected QuillBot-humanized text or upload a .docx, .pdf, or .txt file. Lynote works for quick copy checks, essays, client drafts, and longer rewritten documents.
Fast Copy Review
Run a fast review before grading, publishing, or delivering copy. The report is built for humanizer detection, so it focuses on AI rewriting signals rather than general grammar feedback.
Private Draft Handling
Your submitted copy is not stored or used for model training. This matters when checking academic drafts, client work, or sensitive text that may have been humanized by QuillBot.
Check Whether Copy Looks Humanized by QuillBot
Humanizer tools can change wording while leaving structure, rhythm, and over-polished transitions behind. Lynote reviews those signals and shows whether the copy still looks AI-assisted after QuillBot-style humanizing.
Review Sentences That Still Sound AI-Written
Sentence-level highlights show which lines may still feel machine-written, even after humanizer editing. Instead of judging the whole draft at once, you can inspect specific sentences for QuillBot Humanizer patterns.
Upload Humanized Drafts for a Full Report
Paste copy directly or upload .docx, .pdf, or .txt files that may have gone through QuillBot Humanizer. Lynote returns a readable report with AI, mixed, and human scores plus sentence highlights.
