Book knowledge retention manual steps

[TODO] implement NotebookLM API to automate this

1. Read and highlight book using Apple's Books
   • all highlights will be synced to iCloud
   • .sql file containing all Books highlights can be locally retrieved from macOS at:
     • ANNOTATION_DB_PATTERN = "~/Library/Containers/com.apple.iBooksX/Data/Documents/AEAnnotation/AEAnnotation*.sqlite"
     • LIBRARY_DB_PATTERN = "~/Library/Containers/com.apple.iBooksX/Data/Documents/BKLibrary/BKLibrary*.sqlite"
2. Run script to generate .md file with highlights (retains color coding)
3. Use some online service to convert original .epub of the book you read to a .pdf, e.g. freepdfconvert.com
   • [TODO] try to do this locally via scripting if easy using some library, and high quality enough
4. Upload to NotebookLM:
   • .pdf of entire book
   • .md file of highlights
5. Generate via NotebookLM:
   • Podcast
   • Briefing doc
   • Timeline doc
   • [optional] Study guide
6. Export briefing doc to .pdf and html
   1. Once generation done, click on briefing doc and extract .html section
      • look for it in correspondence of search result "briefing document" (righ-click > inspect element, Shift + Cmd + F)
   2. Copy .html and paste it into new .md file created via VS Code (you can also preview the file via Shift + Cmd + V)
   3. From the .md file tab in VS Code access command palette via Shift + Cmd + P
   4. Type "export" > select "Markdown PDF: Export" (note: requires installing Markdown PDF on VS Code)
7. Repeat previous step for timeline doc
