Tools like ChatGPT, Claude and Grok can quickly summarize public information, giving me a snapshot in seconds instead of hours. Large language models (LLMs), the tech powering these AI tools, are trained on massive datasets pulled from across the open web. Because while LLMs can be incredibly powerful, they're still prone to hallucinations — a polite term for making things up. And if you've spent even five minutes with Google's new AI Overviews (AIOs), you've seen it firsthand. If it were, AI tools would already be flooded by spam from low-quality marketers.
