Content Quality Index (CQI) is an innovative Android application aimed at improving the way viewers assess the quality of YouTube videos. This free tool employs a hybrid model that integrates AI analysis, public participation, and insights from verified subject-matter experts. Unlike traditional metrics that focus on popularity, CQI emphasizes transparency by providing structured context on sourcing, framing, and presentation, empowering viewers to make informed judgments about the content they consume.

CQI is designed for a diverse audience, including viewers, creators, researchers, and institutions, seeking more transparency in online video. By offering quality signals at the point of consumption, it helps users discern the credibility of information without enforcing platform rules or labeling content as true or false. This approach fosters a healthier information ecosystem, encouraging accountability and critical evaluation over authority-driven judgments.
