The episode explains a “public domain AI flipping” strategy: training custom GPTs on 19th-century public domain books (including Project Gutenberg and the Internet Archive) to create niche, highly specific tools that can be monetized quickly via subscriptions or products. It argues most custom GPT monetization fails due to content creation costs or licensing, but public domain works published on or before 1930 can be used and monetized without copyright barriers, with the public domain expanding yearly. The script outlines a four-step process: pick a narrow vertical with an unmet need, curate matching public domain texts, build a custom GPT using prompts and retrieval-augmented generation (RAG), then monetize via recurring revenue using platforms like GPT Plus, Gumroad, or API interfaces. It recommends verticals such as historical accuracy consulting, academic supplementation, content engines for podcasters, and archival tools, while warning about uncertain platform rules, limited precedent, and the need for distribution over technical execution.
