Ask the book
Questions answered
from the text itself.
Ask a question about cost, capacity, demand, or scale. The assistant retrieves passages from both volumes and answers only from what they say, with citations you can click.
Answer
How it works
Grounded, not improvised.
Retrieval
Both volumes are split into passages and embedded into an index that is rebuilt whenever the book changes. A question finds the closest passages — the same ones a careful reader would mark.
Grounding
The assistant is instructed to answer only from the retrieved passages and to say when the book doesn’t cover something. Answers cite volume and chapter, so you can check every claim in place.
Also for machines
The book’s working vocabulary is published as data at /vocabulary, with stable term IDs for other tools and assistants to cite.
