The Challenge

The client wanted to let people generate full books by just typing a topic. Not summaries or outlines — actual books with chapters, cover art, and audio narration. The tricky part was that no single AI model does everything well, so we had to figure out how to get three different ones to work together without the output feeling disjointed.

Our Approach

We split the work across models based on what each one is good at. Claude writes the long-form content because it handles narrative well. Gemini generates images. OpenAI handles text-to-speech for the audiobook version. We built an orchestration layer in Python that manages context between chapters so the book reads like one coherent piece, not a bunch of disconnected essays.
