Why was my topic blocked or flagged?
If your book was blocked before it could be created, a narrow set of topics is off-limits and the draft can't go through as written. If you saw a warning instead, your book is still created. The note just explains how books on sensitive topics are written.
Your topic was blocked
If you saw the message "We cannot create books with prohibited content", one or more phrases in your subject, goals, or topics aren't something we can write a book about. This covers a narrow set of subjects: hate content, violence or self-harm, how to do illegal things, sexual content, specific gambling picks, weapons instructions, partisan campaign material, and a few others. The full list is on our content policy page.
The warning shows you the exact phrases that were flagged. Edit your draft to rephrase or remove them, then retry the review — in most cases that's enough. The flag is usually right, but if you're confident your topic is genuinely educational and isn't on the prohibited list, contact us with the URL of your draft (or a screenshot).
You got an Educational Content note
On topics like health and medicine, mental health, finance and investing, law, employment, housing, and exams and admissions, you'll see a short note on the review step before you pay. Your book is still created; the note is letting you know what to expect in it.
On these topics, your book focuses on how things work in general: what a condition is, how treatments are approached, what different investment vehicles do, how legal systems handle a type of case, what goes into common decisions. What it won't do is diagnose you, prescribe a specific dose, pick a stock, review your contract, or guarantee an outcome. Those kinds of answers need a doctor, financial advisor, or attorney who knows your situation — a book can't replace that, no matter how well-written it is.
TailoredRead books on these topics can still be dense and thorough. Many of our best-received books are in health, finance, and law. They just teach the subject rather than act as your personal professional.
