What is Book Detective (formerly What is that Books?)?
Book Detective is an AI book search engine that finds titles from vague plot memories, character details, or mood descriptions you type in chat. It started as an experimental tool called What is that Book on Joelbooks and now runs as a custom GPT in the OpenAI GPT Store with a curated dataset of 10,000+ titles beyond ChatGPT's training cutoff.
Keyword book finders choke on fuzzy prompts like "fantasy with dragons and a clever heroine." Book Detective combines GPT-4 with Joelbooks' editorial dataset of fresh fiction and nonfiction excerpts, updated weekly with upcoming releases ChatGPT alone cannot see. The trade-off is that it lives inside ChatGPT rather than as a standalone website, so you need a ChatGPT account to use the current version.
Readers who forgot a title but remember scenes use Book Detective to match fragmented descriptions against both the LLM and Joelbooks' quality-filtered catalog. Authors can submit books directly to the dataset. The original whatbook URL on Joelbooks now 404s; Book Detective is the documented successor as of May 2024.
