About
Every quiz platform measures accuracy. UnderstandIQ measures the gap between your confidence and your accuracy — the signal that predicts learning failure before it happens. Upload any PDF, notes, or article. Answer questions at three depth levels. Rate your confidence before each result. Get your Calibration Gap, Overconfidence Score, and Illusion of Understanding index — the four signals that correctness alone never surfaces. Built on HCMS, a DOI-backed cognitive science framework by Muhammad Rayan Shahid. Free to use. Runs on Streamlit.
