FAQPage Schema
How do I create a two-column book analysis from an EPUB or PDF?

To create a two-column book analysis, provide an EPUB or PDF file and a target slug. The pipeline extracts chapters, preserves content on the left, and maps ideas to your life context on the right, outputting a markdown file.

What is personalized chapter-by-chapter book analysis and how does it work?

Personalized chapter-by-chapter book analysis preserves original chapter content in a left column while mapping ideas to your life context in a right column. It processes novels, textbooks, and non-fiction through automated chapter extraction and subagent analysis.

Can I analyze both EPUB and PDF files for educational and personal development workflows?

Yes, you can analyze both EPUB and PDF files for educational and personal development workflows. The pipeline ingests either format, extracts chapters, gathers context, and assembles a final personalized brain page.

How do I render my two-column markdown book analysis into a PDF?

You can render your two-column markdown book analysis into a PDF using the optional brain-pdf rendering step. The pipeline assembles the final markdown file at media/books/<slug>-personalized.md before initiating the PDF render.

What is the best way to map book ideas to my personal life context?

The best way to map book ideas to your personal life context is using a two-column brain page structure. The left column preserves chapter content while the right column applies your brain context to map ideas to your life.

Do I need to manually split chapters before generating a personalized book analysis?

No, you do not need to manually split chapters before generating a personalized book analysis. The pipeline implements end-to-end orchestration that automatically handles file ingestion and chapter extraction before analyzing each chapter via subagents.
