Frequently Asked Questions
Everything you need to know about AI-generated Amazon book descriptions
How does the AI description generator work?
Our tool uses Google's Gemini AI model to generate book descriptions based on your inputs — title, genre, themes, tone, and target audience. The AI has been trained on millions of book descriptions and understands Amazon KDP best practices, HTML formatting rules, and genre-specific conventions. It generates a unique description each time, so you can regenerate until you find the perfect fit.
Is this tool really free?
Yes, your first description generation is completely free with no signup required. To unlock unlimited generations, we ask for your email address — that's it. No credit card, no hidden charges. We offer this as a free resource to help self-published authors create better Amazon listings.
Can I use the generated description on Amazon KDP?
Absolutely. The descriptions are generated with Amazon KDP in mind. They use only HTML tags that Amazon supports (<b>, <i>, <br>) and are formatted for optimal length (150-300 words). You can copy the HTML version directly into your KDP description field. We recommend reviewing and personalising the output before publishing.
What HTML formatting does Amazon allow in book descriptions?
Amazon KDP book descriptions support a limited set of HTML tags: <b> for bold, <i> for italics, <br> for line breaks, and <h2> for subheadings. Other tags like <p>, <ul>, <li>, <a>, and CSS styles are stripped out. Our generator uses only these supported tags to ensure your formatting displays correctly on Amazon.
How long should an Amazon book description be?
Amazon allows up to 4,000 characters, but the ideal length for conversion is 150-300 words. Shorter descriptions don't provide enough information for purchase decisions, while longer ones lose mobile readers (who see only 3-4 lines before the 'Read more' fold). Our generator targets this sweet spot automatically.
How do I choose the best Amazon search keywords?
Amazon gives you 7 keyword slots in your KDP dashboard — these are separate from your description. Use phrases readers actually search for, not single words. Include genre + trope combinations (e.g., 'enemies to lovers fantasy'), reader demographics ('books for teen girls'), and comparison terms ('books like Harry Potter'). Our tool generates 7 optimised keywords alongside your description.
Can I edit the generated description?
Yes, and we encourage it. The AI generates a strong starting point, but your personal knowledge of your book makes the description better. Add specific plot details, adjust the tone to match your voice, and ensure accuracy. Copy the text version or HTML version and edit freely before publishing to KDP.
Does the description work for both ebook and paperback?
Yes. Amazon uses the same description field for both your Kindle ebook and paperback/hardcover editions. The HTML formatting renders on all formats. If you want slightly different descriptions for each format, you can generate multiple versions by adjusting the tone or emphasis.
How is this different from ChatGPT?
Our tool is purpose-built for Amazon book descriptions. Unlike general-purpose AI chatbots, it understands KDP's specific HTML formatting rules, the 150-300 word sweet spot for conversion, genre-specific tropes and language, and Amazon's 7-keyword slot system. It also generates search keywords alongside the description — something you'd need to prompt separately in ChatGPT.
What genres are supported?
We support 22 genres across fiction and non-fiction: Fantasy, Science Fiction, Romance, Mystery/Thriller, Horror, Literary Fiction, Historical Fiction, Young Adult, Middle Grade, Children's Picture Book, Memoir, Self-Help, Business, Health & Wellness, Biography, History, Science, True Crime, Cooking, Travel, Religion & Spirituality, and Poetry. Each genre uses tailored language and conventions.
Your Amazon book description is the single most important piece of marketing copy you will write. While your cover gets the click, your description closes the sale. Data from Amazon seller forums and indie author surveys consistently shows that 70-80% of purchase decisions are made after reading the description — not from the cover, reviews, or price alone.
On mobile devices (where over 60% of Amazon book browsing happens), readers see only the first 3-4 lines of your description before the "Read more" fold. If your opening hook doesn't grab attention immediately, you've lost the sale. This is why professional copywriters front-load the most compelling element — a question, a conflict, or an emotional promise — in the very first sentence.
Anatomy of a Great Book Description
The Hook (Lines 1-2)
Your opening must create intrigue or emotional connection immediately. Ask a provocative question, present a conflict, or make a bold promise. This is what shows above the fold on mobile.
The Body (3-5 Paragraphs)
Short paragraphs of 2-3 sentences. For fiction: build tension without spoiling the ending. For non-fiction: outline the transformation the reader will experience and key takeaways.
The Call-to-Action
End with urgency. "Scroll up and click Buy Now", "Start your journey today", or "Grab your copy before the price goes up." A clear CTA increases conversion by 15-20%.
5 Common Description Mistakes to Avoid
Starting with 'In this book...' or 'This book is about...'
Start with a hook — a question, conflict, or emotional promise that grabs attention instantly.
Writing a summary instead of sales copy
Your description is a sales page, not a synopsis. Create desire, don't just inform.
Spoiling the ending or key plot twists
Tease the conflict and stakes, but leave the resolution as a mystery the reader must buy to discover.
Using plain text with no formatting
Use <b>, <i>, and <br> tags. Formatted descriptions convert 30% better than plain text walls.
Writing 500+ words
Keep it 150-300 words. Longer descriptions lose mobile readers and dilute your message.
Amazon HTML Formatting
<b>text</b>Bold text
<i>text</i>Italic text
<br>Line break
<h2>text</h2>Subheading
All other HTML tags (<p>, <ul>, <a>, CSS) are stripped by Amazon.
KDP Search Keywords
Amazon gives you 7 keyword slots in your KDP dashboard. These are separate from your description and are invisible to readers.
Use multi-word phrases, not single words. "Enemies to lovers fantasy romance" is better than "romance".
No commas needed— Amazon treats each box as one phrase. Don't waste characters on separators.
Include comparison terms like "books like Harry Potter" and reader demographics like "gifts for teen boys".
