I appreciate the attempt, but honestly, I'm not really sure how you would build something like this. You'd have to be able to filter audio, video, images and text.<p>I'm not even sure if there exists a corpus of copyrighted content anywhere to compare against. You're probably going to have to build it yourself. And keep it up to date with not just newly generated content, but also content whose copyrights expired.<p>Frankly, even for companies of the FAANG scale, this is a tough challenge, and I don't think a startup is going to be able to handle this.
