Frequently asked questions
- What is TailoredRead?
TailoredRead creates complete, full-length nonfiction ebooks, written specifically for you.

- How is the book tailored to me?
Before anything is written, you answer a few short questions about your goals, your background, and the topics you care about. Your book is then planned around your answers: written at your level, focused on your goals, and covering the topics you chose, instead of the one-size-fits-all book a store sells everyone.
- Will it read like generic AI content?
No. Your book isn't a chat transcript: it's planned chapter by chapter before a single word is written, told in a clear book voice, and explains ideas visually with charts, tables, and diagrams. After writing, every book goes through an editorial pass that polishes chapters so the book reads consistent from start to finish. Judge for yourself: browse thousands of sample books on our Explore Books page.
- How accurate is the content?
Our AI first checks whether your subject needs live research. Niche and fast-moving subjects are researched before writing, and the book plan and chapters are grounded in what it finds. After writing, every book goes through a quality pass that checks its facts and consistency, and researched books list their sources in a Notes section at the back.
- How long is the book?
You choose the length: Comprehensive (250-300 pages), Detailed (150-200 pages), Essential (70-100 pages), or Short (30-50 pages).

Yes. Every book includes charts, tables, and diagrams: timelines, checklists, step-by-step guides, decision trees, comparison tables, matrices, and bar charts. A typical book includes dozens of these visual elements.
- Can I read it on Kindle? What formats can I download?

- How much does it cost?
About the price of a regular ebook. The exact price depends on your book's length and complexity, from $2 for the shortest books to $35 for the most comprehensive, and it's shown when you review your book, before you commit to anything.

- Can I preview the book before purchasing?
