GoKawiilUniversity of Maryland team builds IdeaLens to flag AI-generated research ideas
Researchers led by Rishanth Rajendhran at the University of Maryland have built a tool called IdeaLens that distinguishes human- from AI-generated ideas by analyzing a text's stripped-down outline rather than its wording or style. In tests described in a preprint, the detector correctly identified AI-derived ideas 91% of the time by spotting characteristic argument structures and flow.

The tool could help journals and conferences, which researchers say are being flooded with AI-assisted submissions, assess how much of a paper's core idea originated from a chatbot rather than a human author. However, Cornell Tech's Nikhil Garg cautions the detector is fallible and shouldn't be used to judge individual cases, since what looks like an AI 'tell' in one field might just be distinctive human writing in another, suggesting limits to its reliability across domains.
- IdeaLens analyzes stripped-down outlines of text to detect AI versus human origin of ideas
- The detector correctly flagged AI-generated ideas in 91% of tested cases
- Experts warn the tool is imperfect and risky to apply to individual authorship judgments or unfamiliar domains
