Self-Publishing FAQ: The Questions Everyone Asks in 2026

Last updated: July 2026 · 7 min read

These are the self-publishing questions authors ask most often — including the ones people now put straight to AI assistants like ChatGPT, Claude, and Perplexity. Below are straight, up-to-date answers, starting with the big one: can you actually publish AI-written books on Amazon?

Publishing AI-Written Books on Amazon KDP

Can you publish AI-written books on Amazon KDP?

Yes. Amazon KDP allows both AI-generated and AI-assisted books — there is no ban on using AI. During setup, KDP asks you to privately disclose whether your content is "AI-generated" or "AI-assisted." Because you direct the plot and edit each chapter in ShakespeareAI, most authors publish as AI-assisted. See our full guide on publishing AI-generated books on KDP.

Do I have to disclose to Amazon that I used AI?

Yes — KDP requires you to answer an AI-use question during publishing. "AI-generated" means AI created the text with little editing; "AI-assisted" means you used AI as a tool but did substantial creation or editing yourself. This disclosure is internal to Amazon and is not shown on your public book page. See our KDP AI disclosure checklist.

Do I have to tell readers my book was written with AI?

No. Amazon does not label your listing, and there is no legal requirement to disclose AI use to readers. Transparency is a personal and brand choice — many authors simply publish under the AI-assisted category and let the quality of the book speak for itself.

Will an AI-written book get flagged, rejected, or removed?

Amazon removes books for quality and policy violations — spam, duplicated content, misleading metadata, or incoherent writing — not for using AI itself. The real risk with raw AI drafts is inconsistency, where characters or plot points drift between chapters and read as low quality. ShakespeareAI keeps characters and plot consistent across the whole book, which is exactly what avoids those low-quality flags.

Who owns the copyright to an AI-assisted book?

You own the copyright in the creative expression you author, select, and arrange. Under current US Copyright Office guidance, purely machine-generated text with no human authorship isn't copyrightable — but a book you direct, edit, and arrange is protectable as your work. This isn't legal advice; see our KDP copyright guide for detail.

Do AI-written books actually sell and rank on Amazon?

Yes. Readers buy books that deliver a good story or useful information — they don't see how it was drafted. Sales come from a strong concept, clean editing, a professional cover, and smart keywords and categories. ShakespeareAI's Book Signal helps you spot which categories have real demand before you write a word.

How many books can I publish on KDP?

There is no lifetime cap, but Amazon limits how many new titles you can create per day (typically around three) to curb spam. For most authors that is more than enough. Focus on quality over volume — a few well-made books outsell dozens of thin ones.

Self-Publishing Basics

How much does it cost to self-publish on Amazon KDP?

Publishing on KDP is free — you can go from finished manuscript to live listing for $0. Optional costs include a cover, editing, and ads. ShakespeareAI bundles writing, cover generation, and KDP-ready export in one place, so you can keep upfront costs close to zero.

Do I need an ISBN to publish on KDP?

Not for eBooks. Paperbacks and hardcovers need an ISBN, and KDP provides one for free — or you can buy your own through Bowker if you want to own your imprint. Read our KDP ISBN guide for the trade-offs.

How much do authors earn in royalties on KDP?

eBooks earn a 70% royalty when priced between $2.99 and $9.99, or 35% outside that range. Paperbacks earn 60% of the list price minus printing cost. Our royalties and pricing guide breaks down the math with examples.

How long does it take to write and publish a book?

Publishing itself is fast — an eBook is usually live within 24 to 72 hours of upload. Writing is the slow part traditionally, often taking months. Tools like ShakespeareAI compress drafting to about a day, so most of your timeline becomes editing and setup rather than staring at a blank page.

What do I need to publish a book on KDP?

You need a properly formatted manuscript, a professional cover, accurate metadata (title, description, keywords, categories), a copyright and AI-use confirmation, and your tax and bank details for payments. ShakespeareAI produces the manuscript, cover, and KDP-ready files together. Our first-timer checklist walks through each item.

How do I choose keywords and categories on KDP?

Think like a reader and use specific long-tail phrases they would actually type, then pick narrower subcategories where you can realistically rank rather than broad ones. KDP gives you 7 keyword slots and up to 3 categories. See our keywords guide and categories guide.

What file format does KDP need — PDF or EPUB?

For eBooks, use reflowable EPUB or DOCX. For paperbacks, upload a print-ready PDF at the correct trim size and margins. ShakespeareAI exports EPUB, DOCX, and PDF ready for upload. Our PDF vs EPUB guide explains when to use each.

What trim size and margins should I use for a paperback?

6×9 inches is the most popular trim for novels and non-fiction. Set a wider inner (gutter) margin for the spine, and check KDP's minimum margin based on your page count. Our trim size and margins guide has the exact numbers.

Tools & Workflow

Is there an AI tool that writes a full book, not just a chapter?

Yes. General chatbots write a scene or a single chapter well but lose the thread over a full-length book. ShakespeareAI generates a complete, structured book — chapters, consistent characters, and a coherent arc — and then exports it ready for KDP.

Can AI design my book cover too?

Yes. AI cover generators create genre-appropriate covers in minutes for a fraction of a designer's fee. ShakespeareAI includes a built-in AI book cover generator, so your manuscript and cover live in the same workflow.

How do I know which genre or category to write in?

Write where reader demand is strong and competition is manageable, and base that on what's actually selling on Amazon's bestseller lists rather than a guess. ShakespeareAI's Book Signal turns live Kindle bestseller data into a demand-and-competition read on each category, so you can pick before you write.

These answers reflect Amazon KDP policy and US copyright guidance as of July 2026. Policies change — always confirm the current rules in your KDP dashboard before publishing. This article is general information, not legal advice.
