AI Detector

In one breath

A tool that claims to tell whether text or images were made by AI. In practice they are unreliable — they routinely accuse honest human writing.

In more detail

An AI detector is a tool that claims to tell whether text or images were made by AI — paste in an essay, get a verdict like ‘likely AI-generated.’ The trouble is that it’s guessing from statistical patterns, and it’s wrong in both directions distressingly often.

It matters because these verdicts carry real consequences — students accused, writers rejected — on evidence far flimsier than it looks. Polished human writing gets flagged; lightly edited AI text sails through. Treat a detector score as a hunch, never as proof, and be very careful accusing anyone with one.

📌 See it in action

A student writes an essay entirely herself — careful structure, clean grammar. A detector flags it as AI-written, largely because tidy, formal prose resembles machine output. Meanwhile a classmate’s AI-generated draft, roughed up with a few casual edits, passes as human. The tool confidently failed twice.
