Show HN: Illustrative – AI pipeline that turns books into graphic novels

I like the idea of taking one thing and turning it into another—very much inspired by NotebookLM and wondered what it might take to generate full graphic novels, with consistent characters, narrative flow, story arc, etc.

Developed a 7-pass scripting enrichment system (beat analysis, adaptation filtering, character deep dives) before generating any images.

Dual backend: Google Gemini for scripting (2M context window) and either Gemini or OpenAI for image generation with 3-tier model fallback (comparing the performance of both).

It's not great. Would love feedback on the pipeline.
