AI Detector — Check Essays for AI Writing Signals

What is AI Detector

AI Detector is a sentence-level checker that helps students, writers, and editors review text for patterns commonly associated with AI-generated writing.

Paste an essay, article, paper, or draft, and Quilbot flags passages that may look overly formulaic, repetitive, generic, or unnaturally polished.

Each result includes a short explanation so you can understand why a sentence was flagged before deciding whether it needs revision.
