IdeaLens detects whether a document's ideas came from AI, not who wrote it

Researchers at the University of Maryland introduced IdeaLens, a detector that identifies the provenance of a document's ideas rather than its prose. Trained on one million outlines extracted from web documents, it flags AI ideas in 68% of human-written stories, versus 8% for Pangram 4.
