About Us
We're two Stanford grad students who like building things. Indexia started because one of us had to index a book and thought there had to be a better way.
Ben Vagle
Ben is a JD/PhD candidate at Stanford. He co-authored Command of Commerce (Oxford University Press, 2025), and the experience of going through the publishing process — including indexing the book himself — is what got him thinking about building Indexia.
Will Dinneen
Will is a JD candidate at Stanford with a background in data science. He previously did research at UPenn, co-authoring multiple papers about politics, economics, and bibliometrics. He also worked on the product team at Resultid.ai.
Why We Built Indexia
Back-of-book indexing is one of those things most people never think about until they have to do it. Then you realize it's genuinely hard: you're reading every page, deciding what matters, tracking hundreds of page references, building cross-references, and formatting the whole thing to the Chicago Manual of Style. For a 300-page book, that can take a professional indexer a week or more. It can take an untrained author even longer.
We built Indexia to change the math. The software uses thousands of focused AI queries to extract and curate terms, identify relationships, generate subentries, and compile page references. At every stage, you can review and modify what the AI has done. The result is a tool that can cut indexing time by roughly 80% while still giving you full editorial control over the final product.
We're both technical — between us we have backgrounds in data science, analytics, and software engineering — and we've tried to build Indexia the way we'd want to use it ourselves: fast, transparent about what the AI is doing, and always deferring to human judgment on the decisions that matter.
