SourceGuard empowers content creators and website owners to control how AI models interact with their digital assets. It solves the problem of unauthorized AI scraping and summarization by providing tools to define access policies, embed digital watermarks (inspired by SynthID), and specify usage rights for AI systems. Simultaneously, it allows content owners to generate AI-optimized versions of their content (e.g., structured Markdown, knowledge graph formats) for *authorized* AI consumption, ensuring proper attribution and potential monetization. This platform acts as a smart gateway, protecting intellectual property while facilitating controlled, beneficial AI integration.
