1. Outcome
Helps anyone write a real book with AI: by talking, typing, uploading a document or photographing pages of handwriting.
2. The problem
Memoirs, family cookbooks and handwritten manuscripts sit unfinished in drawers.
3. My responsibility
Founder and sole owner. I directed the build with Claude Code.
4. What was built
- Seven kinds of book, including memoir, cookbook and "shoebox", where an existing handwritten manuscript is transcribed and typeset.
- Chapter-by-chapter interviews, dictation in the browser and Word import.
- A page-turning reader, three versions of each chapter and full version history.
- Editor invites, and PDF and EPUB export.

5. AI and controls
- Claude Haiku asks the follow-up questions.
- Claude Sonnet transcribes handwriting. Testing showed the cheaper model misread handwriting without flagging it, so I moved the job up a tier.
- Claude Opus writes the prose and re-checks the pages the transcriber flags.
