Tony Stark could never

Here's a fun one. A video shows a person suiting up in an iron exoskeleton straight out of a sci-fi movie (The Avengers typa one). The post's caption is upfront: ‘Can you believe this stunning visuals was created by Ai?’ It's a brilliant showcase of what generative AI can do. But here at isFake, we are not getting too impressed. Because even if super-realistic, AI stays AI. And we can detect it.

We ran the stunning clip through our AI video detection model. The result was precise: 79% AI-generated. This score is powerful. isFake detector performs a granular video authenticity check, analyzing every detail, texture, and physics to quantify the synthetic footprint. Additionally, it gives out the complex frame-by-frame analysis. Ready to try yourself?
