What is SearchGPT?
SearchGPT at searchgpt.ai is a spreadsheet generator from Owens Laboratories. You describe the table you want in a prompt, hit Generate, and the site builds a spreadsheet from your instructions instead of making you lay out rows and columns by hand.
The homepage workflow is built around that single prompt box. Simple requests return quickly, while more complicated spreadsheet layouts can take up to a minute to finish generating.
Sign in and sign up run through the site's auth pages, so you need an account before you can use the generator. The product is aimed at anyone who wants spreadsheet output from plain-language directions rather than manual setup in Excel or Google Sheets.

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.
