I used Claude to build a complete data extraction pipeline for a popular current best seller book series: audiobook -> text (via whisper) -> local LLM (qwen) -> database. Not once did it seem to acknowledge or care about copyright. It even used knowledge it already had about the books to exclude certain ones before beginning since the character I was interested in did not appear in those. It definitely had context of what we were working on.
Why would you go from audiobook to text? Is there no epub available?
