Indexia Featured on Armed with A Book
Indexia is featured in a new interview on Armed with A Book, the long-running blog about books, reading, and the craft behind them. In "The Map at the Back of the Book: A Conversation with the Creators of Indexia," interviewer Kriti K talks with Indexia's creators, Will Dinneen and Ben Vagle, about why they built an AI tool for back-of-book indexing and what the work taught them about how knowledge is structured.

What the conversation covers
- Why indexing is interpretation, not transcription. An index isn't a keyword list. It's a reading of a book—decisions about granularity, hierarchy, terminology, and cross-references that reveal what a text is actually about.
- The cost problem Indexia solves. Professional indexing runs $1,000–$3,000 and takes weeks. Indexia produces a standard index for $99, with an interactive editor so authors stay in control of the final result.
- Why generic AI fails at this. Off-the-shelf LLM prompts match professional indexers only 20–40% of the time. Indexia's 27-phase pipeline and purpose-built prompts close that gap.
- Keeping AI honest. Every term Indexia extracts is linked back to the exact passages where the concept appears, so authors can verify entries against the source text.
In their words
"A great index helps you discover things you didn't know to look for."
"The gap between the naive approach and the engineered approach is enormous, and that gap is really the core of Indexia's value."
