AI Data Scraper
Downloads web content to train AI models

Expected Behavior

It's generally unclear how AI Data Scrapers choose which websites to crawl and how often to crawl them. They might choose to visits websites with a higher information density more frequently, depending on the type of AI models they're training. For example, it would make sense that an agent training an LLM (Large Language Model) would favor sites with a lot of regularly updating text content.
