Track individual book values and your total library worth with pricing that’s always private to you, and decide whether your collection is visible only to you or shared publicly.
Each book includes rich insights that links titles to their authors, artistic movements, exhibitions, and related works. Explore how ideas evolve across art, design, and culture through connected books, creators, and influences.
In January 2025, as wildfires swept through Los Angeles and threatened our home, we realized years of collecting books had gone uncataloged. Faced with the possibility of losing everything, we started recording each book by hand. It didn’t take long to see how slow and impractical that was. There had to be a better way. What began as a simple tool to track and insure your library is now evolving into a platform to digitize, discover, and trade books.
