What PPTDetector is

PPTDetector is a detector for slide decks rather than documents. It takes ppt and pptx files, analyses the text, images and structure for AI-generated traces using statistical features such as perplexity and sentence length variation, and produces a visual report.

What you can do with it

  • Check a deck for AI-generated content
  • Review slides in education or business settings
  • Screen several presentations in a batch
  • Produce reports for review records
  • Compare decks across a cohort

Who it is for

  • Teachers reviewing slide-based work
  • Corporate reviewers checking proposals
  • Institutions running batch checks

What to watch out for

  • Detectors built on statistical features misclassify clean, conventional human writing and miss lightly edited AI text; treat output as a signal only
  • Presentation structure is heavily templated, which increases false positives
  • Never decide an academic or hiring case on a report alone
  • Uploaded decks may contain confidential material

Pros & cons

✓ What we like

  • Purpose-built for a common format
  • Checks images and structure too
  • Batch screening supported

! What to watch out for

  • Statistical detection is unreliable
  • Templated decks raise false positives
  • Not sufficient evidence alone

FAQ

Does a report prove AI use?

No. It is a signal needing human review and discussion.

Why are decks often flagged?

Templated structure and short, even sentences trigger statistical detectors.

What should I avoid uploading?

Decks containing confidential or unpublished material.
