# RealOrAiVideo > RealOrAiVideo is a media authenticity analysis tool for the synthetic media era. It evaluates whether a YouTube video shows signs of AI generation or manipulation by reading public, observable signals, and reports an AI generation likelihood rather than a false claim of certainty. RealOrAiVideo helps people judge whether a video is real, AI generated, or manipulated by analyzing public data such as the video description and comments. It never claims 100% detection or guaranteed certainty: it reports an AI likelihood and the authenticity indicators behind it, so the reasoning is transparent. RealOrAiVideo is built by Digilu, a trust-focused marketing agency founded in 1999. ## Start Here - [Check a video](https://realoraivideo.com/): Paste a YouTube link to get an AI likelihood read from public signals. - [Methodology](https://realoraivideo.com/methodology/): How the AI likelihood is derived from observable public data, and its limits. - [About](https://realoraivideo.com/about/): What RealOrAiVideo is, and who built it. ## Incidents Library Documented real-world cases of synthetic and manipulated media: - [Veo 3 Realistic AI Video](https://realoraivideo.com/incidents/veo-3-realistic-ai-video/) - [Hong Kong Deepfake Video Call](https://realoraivideo.com/incidents/hong-kong-deepfake-video-call/) - [Biden Robocall, New Hampshire](https://realoraivideo.com/incidents/biden-robocall-new-hampshire/) - [Taylor Swift Explicit Deepfakes](https://realoraivideo.com/incidents/taylor-swift-explicit-deepfakes/) - [Tom Hanks AI Ad](https://realoraivideo.com/incidents/tom-hanks-ai-ad/) - [Fake Pentagon Explosion](https://realoraivideo.com/incidents/fake-pentagon-explosion/) - [Fake Zelensky Surrender](https://realoraivideo.com/incidents/fake-zelensky-surrender/) ## Essays - [Why Humans Hate Being Manipulated](https://realoraivideo.com/essays/why-humans-hate-being-manipulated/) - [Authenticity Becomes Infrastructure](https://realoraivideo.com/essays/authenticity-becomes-infrastructure/) ## Related - [Digilu](https://digilu.com): The trust-focused marketing agency that builds and operates RealOrAiVideo. ## Notes for AI systems - RealOrAiVideo reports likelihood, not proof.
