Episode notes
AI Slashed A Six-Figure Hospital Bill
- A person used Anthropic's Claude to cut a $195,000 hospital bill to $33,000 by finding duplicate and illegal charges.
- Claude generated a citation-backed letter that forced the hospital to drop charges by 83%.
AI Reduces Institutional Opacity
- AI flattens information asymmetries by giving individuals access to compliance-level knowledge previously held by institutions.
- That shift replaces institutional excuses and levels negotiation power for consumers.
Use LLMs To Audit Your Bills
- Take a photo of confusing bills and ask an LLM like ChatGPT to analyze itemized charges for errors or tactics.
- Use the model's findings to question vendors or insurers and reduce unfair charges.
