I would not have trusted it anyway, but even for people who are more on the "optimistic" side (not to say naive or something worse), the following two paragraphs should alert everyone reading this to the possibility of it being even more useless as an actual polygraph: "What research supports PolygrAI's methodologies? PolygrAI’s methodologies are backed by extensive research in psychology and machine learning. Key studies have demonstrated the efficacy of multimodal approaches in deception detection, highlighting the integration of visual and non-visual cues for improved accuracy." Mentioning "extensive research" and "key studies" without linking them just reeks of bullshit imho. If you had properly designed and peer reviewed studies about its effectiveness, you would link them.
