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?▼

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