About AI Detector

Focused tools for understanding and improving writing.

AI Detector is a mobile-first writing utility supported by a growing collection of free browser tools and practical guides.

What we build

The AI Detector app helps people inspect text for patterns associated with AI-generated writing, compare multiple detector signals, work with documents and images, and revise drafts on iPhone and Android. The website provides supporting education and free utilities for counting, readability, citations, document preparation, and reference integrity.

Why the website tools are free

Many writing tasks should not require an account or a subscription. Our browser tools are designed to solve a narrow job well, process writing locally whenever possible, and make their limitations visible. The mobile app remains the place for the complete detection and revision workflow.

Our product principles

  • Useful before promotional: a free tool should complete the task it promises.
  • Private by default: text and document processing stays in the browser when the task allows it.
  • Clear about uncertainty: an AI detector score is a probability signal, not proof of authorship.
  • Built for mobile: key actions should remain comfortable on a phone, not only on a desktop.
  • Maintained over time: pages and tools are reviewed, tested, corrected, expanded, or retired based on usefulness.
We do not claim that AI detection can determine authorship with certainty. High-stakes decisions should include the original work, revision history, context, and human review.
