FAQ

How does this AI content checker work?

It analyzes patterns such as repetition, vocabulary diversity, and sentence structure to estimate AI-likeness.

Can AI content checkers be wrong?

No. All analysis runs locally in your browser and is not uploaded.

What length of text works best?

Longer samples (200+ words) provide more reliable estimates than short snippets.
