Readable PDF text
Analyzes extractable writing without keeping the original document in result history.
PDF AI detector and AI checker for complete documents
DeepfakePolicy extracts readable text from the PDF, samples long documents across their pages and shows how much material was analyzed. This AI checker for PDF files returns a writing-pattern signal, not proof of authorship.

Coverage details
Reports page count, analyzed characters and whether sampling was required.
Document context
Notes available authoring metadata and embedded-image count separately from the text score.
Reading the result
Use the score as a signal, not proof
The result estimates statistical writing patterns in extractable text. It cannot determine whether an author used a grammar tool, translated the document or edited generated material heavily.
Important limitation: Image-only scans require OCR and may contain too little extractable text. Short, formulaic, translated and highly technical documents can produce misleading results.

Questions people ask before checking
How do I check if a PDF was written by AI?
Upload the PDF so the detector can extract and sample its readable text. Review the AI-generated and AI-assisted writing signals together with the reported page coverage, then check drafts, sources and the authoring process.
Can a PDF AI checker prove who wrote a document?
No. It estimates writing patterns in extractable text and can be affected by translation, editing, technical language and short samples. It cannot prove authorship or identify a particular AI tool.
