BookBuilder: AI System for Creating Custom Books

[Nachoeigu]

Hi everyone,

I’m happy to share a project I’ve been working on that’s built entirely with LangChain & LangGraph.

BookBuilder is an AI system designed to help users create an entire book from scratch, based on their custom instructions. The idea behind it is to simplify the process of book creation by breaking down the big process of book invention into smaller, manageable parts, each handled by an AI agent specialized in a specific stage of the writing process.

Each phase of the book creation is handled by specialized AI agents. These agents refine your ideas, outline key elements like plot and character arcs, and critique drafts until they meet high-quality standards. The entire process is interactive, allowing for feedback loops (thanks LangGraph) at every stage, so your input shapes the final product.

Once the book is complete, the system can even translate it into different languages. With customization options for how the AI works—like selecting models and choosing critique cycles—you’re in full control of the creative process. Book Builder With AI makes writing an immersive and collaborative experience, producing a polished final draft that’s ready to share or enjoy.

If you’re interested in seeing how it works and some book examples, you can check the repository here. I’m still working on refining the system, and any feedback or suggestions from the community would be greatly appreciated.

Looking forward to hearing your thoughts and ideas!
