About Detecting-AI.com

AI Detector is a text analysis tool designed to help users determine whether writing was produced by AI. It targets individuals who review or edit content, educators and editors, and developers integrating AI-content checks into apps. The tool inspects text and provides an overall AI score along with highlighted passages in their original context.

The detector emphasizes context and signals rather than a single definitive percentage. It is designed to show where a signal comes from and to support review with highlighted passages, not to prove authorship.

Users can paste text, upload TXT, PDF or DOCX files, or start typing to scan. The interface presents an overall AI score and highlighted sections for closer examination.

Results stay in the browser during sign-in, and the system supports multiple use cases including education, editorial review, publishing and personal writing.

Use cases

  • Education: identify passages worth discussing while keeping drafts, sources and student context in the decision.
  • Editorial review: review drafted content and focus on changes in the writing.
  • Publishing: add a measured signal to existing review workflows.
  • Personal writing: compare revisions to see how the signal changes.

The detector is designed to review patterns commonly found in text from GPT, Claude and Gemini model families, including edited or mixed drafts.
What is the AI detector accuracy?
The detector reports 99% accuracy and a false positive rate under 1%.
