AI Detector for PDF

Why choose our PDF AI Detector
Deep Document OCR
Our engine extracts text from scanned PDFs and complex layouts with high precision, ensuring no AI-generated content hides in images or tables.
Multi-Model PDF Scanning
Specifically tuned to identify the linguistic fingerprints of GPT-4, Gemini, and Claude within formal reports, whitepapers, and academic submissions.
Structural Analysis
We analyze the flow and syntax of entire documents, detecting subtle AI-assisted paraphrasing that generic text-only scanners often miss.
Global Language Support
Process international PDF reports in English, Spanish, French, German, and more, maintaining detection accuracy across diverse technical vocabularies.
Enterprise-Grade Privacy
Your sensitive PDF data is protected. We use 256-bit encryption and never store your documents or use them to train our models.
Visual Heatmaps
View your PDF with a color-coded overlay. We highlight specific paragraphs and sentences likely to be AI-generated for rapid manual review.

Specialized PDF Forensics
Unlike basic text scanners, our tool is built for the PDF format. It accounts for document metadata, formatting, and technical jargon to distinguish human expertise from AI-generated filler.

Full Document Integrity Reports
Download a comprehensive PDF audit report. Each analysis includes a global probability score, page-by-page breakdowns, and specific markers of AI-generated patterns.

Evolving Detection Logic
As AI models update, so do we. Our algorithms are trained on the latest PDF-based datasets to ensure we catch even the most sophisticated “humanized” AI outputs.
