# Team Cumberland - **Event:** [Built with Opus 4.7: a Claude Code hackathon](https://cerebralvalley.ai/e/built-with-4-7-hackathon) - **When:** Apr 21 at 12:00 PM – Apr 27 at 2:00 AM (EDT) - **Where:** Online - **Team:** [Dan Cumberland](https://cerebralvalley.ai/u/dancumberland) - **GitHub:** https://github.com/dancumberland/Book_Project - **Demo video:** https://youtu.be/v_k0A9SnMZU - **Gallery:** https://cerebralvalley.ai/e/built-with-4-7-hackathon/hackathon/gallery - **Page:** https://cerebralvalley.ai/e/built-with-4-7-hackathon/hackathon/gallery/224 Reading time keeps ending the same way. We close the book early because we can't stand reading it. Our kids notice. We notice. And the books are everywhere — every shelf, every order from every store, sent home in every backpack. A long tail of writing that connects no one to anything. The world is dying for stories that move people, and most of what's getting made is filler. Two parents asked the obvious question: could Claude help us write the book we'd actually want to read to our own kids? Two extremes already exist and both produce a lot of mediocre books. AI writing the whole thing — slop. A human writer alone with a blank page — sometimes brilliant, often forgettable, frequently never finished. Same root cause: neither extracts the actual writer's actual voice and meaning. AI can make words, but not meaning. Meaning lives in the author. The Factory's job is to draw it out. The Book Factory is an AI-native publishing platform for authors, designed around the author rather than around the AI. The author is interviewed by the system on world, characters, voice, plot, and scene; their reference shelf and existing prose seed the style; every interview output becomes a typed contract that downstream agents must satisfy. We're starting with illustrated chapter books because that's what our first series needs. The pipeline produces any chapter book in any fiction genre. What you're seeing in this submission is the proof of concept. Stacia is an educator and dedicated reader. Dan builds AI-native production systems. We have three kids. We are the hardest possible users. We refuse to ship a book to our own kids that we wouldn't want to read. Our prototype effort is three books on Amazon by June 2026, written by us using only the Factory we're building. Eating our own cooking, with our daughter as the first-gate test reader. What we found this week: the book we're writing is better than what either of us would have produced alone. We probably never would have finished it. And the story itself is better — Claude drove the story-craft research that connected dots we wouldn't have seen. Once the proof is in, the Factory becomes a platform other authors can acces— authors with a story they can't quite finish, or who are tired of producing words that don't have meaning underneath them. The bet is bigger than three books. AI-assisted writing done right is how we raise the quality and the quantity of human-authored stories that actually move people in a world dying for them. AI can flatten meaning, and AI can amplify it. We're building the path that amplifies. Brings us closer in. And helps us make things that matter. PS - The soul of this project is a 9 year old half girl nicknamed Piña, who just moved to a new country and new school and is trying to find her way. She's thoughtful and funny. Read the first chapter or two.
