What is seo.ing?
seo.ing turns product URLs and site lists into long-form review posts and top 10 roundup articles using coordinated crawler, outline, writing, and image agents. Marketers and site owners use it to publish comparison content without hiring freelancers for every draft.
Most AI writing tools hand you a blank editor and expect you to supply the research. seo.ing starts with crawling: you feed it one product URL or a list of sites, then outline and title agents propose structure you can edit before writing and image steps finish the piece. That narrow focus on review and roundup formats is the trade-off. It is not a general blog generator for arbitrary topics.
Plans are credit-based with monthly article caps on the public pricing page, from two free articles up to 120 on Enterprise. The interface is available in English plus nine additional languages, including Simplified Chinese, Traditional Chinese, Korean, Japanese, Portuguese, Spanish, German, French, and Vietnamese.
seo.ing runs on a Nuxt.js front end with Tailwind CSS styling and Cloudflare delivery. The company identifies itself as SEO.ING, Inc. on the site footer and lists [email protected] for privacy and support requests.

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.
