AI Policy✨

I do not use large language model (LLM) AIs such as ChatGPT* to index. These LLMs fail at the indexer's primary task—to ensure readers find needed information.

AI/LLMs are guilty of:

• Severe under-indexing, with as few as 20-40% of the access points of human-generated indexes, which can prevent readers from locating desired information and mislead them into thinking that omitted information isn’t in the book at all
• Absent/near-absent index structure, especially cross-references, which prevents the reader from effectively navigating to subtopics and related topics while misrepresenting the focus of the book
• Hallucinations (including invented page references and even wholly nonexistent topics), which waste the reader's time and break the trust between the reader and the book

For more about this subject, you can access the 2025 white paper "LLM-Generated Book Indexes: Can They Replace Professionally Created Indexes?" here. When I index for you, I analyze, write, and edit with a human brain and its awareness of context per quality standards.

*Sources say a request made through ChatGPT consumes 10x the electricity of using Google and some searches cause 50x more CO2 emissions than others. Data centers also must stay cool, necessitating massive amounts of precious water. Microchips that power AI require rare earth elements and increase the amount of mercury and lead e-waste in the environment.
