AI Video Watermark

A Chrome extension that adds highly visible watermarks to AI-generated YouTube videos for transparency and EU AI Act compliance.

When AI video creators mark their content as "AI-generated," YouTube currently only adds a small "Altered or synthetic content" notice buried at the end of the video description (as of December 2024). Most viewers never check descriptions, making it easy to miss that a video is AI-generated—even when properly labeled by the creator.

Why This Matters:
In an age when AI-generated videos are nearly indistinguishable from reality, transparency about content origin should be mandatory and visible. Watching a documentary history channel that uses AI-generated images or clips without clear disclosure should not be acceptable. The EU AI Act will require clear labeling of AI content by August 2026.

How It Works:
This extension detects AI-generated content through multiple methods:

Official YouTube labels (highest confidence) - Detects when creators mark content as "Altered or synthetic"
Hashtag analysis (medium confidence) - Scans for AI-related hashtags like #Sora, #AIVideos, #OpenAI
Title and description scanning (lower confidence) - Looks for AI-related keywords

When AI content is detected, a prominent watermark appears on the video player—impossible to miss.
