Which Should You Choose?

Decision guide based on your specific needs

Choose AI Indexing When:

  • Budget is limited (under $500 for indexing)
  • Book is standard non-fiction or fiction
  • You want consistent, repeatable results
  • You're indexing multiple books regularly
  • Content is well-structured and clearly written

Choose Manual Indexing When:

  • Time isn't a critical factor (4+ weeks available)

Hybrid Approach Works When:

  • Start with AI for speed, then human review
  • Use AI for initial draft, professional for polish
  • AI for bulk content, human for specialized sections
  • Want best of both worlds: speed + expertise
  • Learning to index - AI as teaching tool
  • Multiple revision cycles needed
