Home Library Companion

Point it at a shelf — it reads every spine. Whole-shelf scanning, household sharing, and Ask: answers from the books you actually own.

Point the camera at a full shelf. Home Library Companion reads the spines and catalogs every book - a 40-book shelf takes about a minute. Barcode, copyright-page, and cover scanning are there too, plus plain search, but the shelf photo is the fast way in.

Then it remembers where everything lives. Every book gets a real address - building, room, bookcase, shelf - so "do we own this?" and "where did it go?" both take seconds.

ASK YOUR OWN LIBRARY Ask in plain English - "which of my books cover rose care?" - and get answers drawn only from books you actually own. No internet recommendations, no invented titles.
