Amazon Book Description Generator (HTML Formatting + AI Blurb Writing)

Writing a book description is hard enough. Formatting it correctly for Amazon adds another layer of frustration.

This Amazon Book Description Generator is designed to help authors write and format professional book blurbs using Amazon-approved HTML. It removes the guesswork around formatting, spacing, and layout, and includes optional AI assistance to help improve clarity, flow, and readability.

In addition to Amazon book descriptions, this tool also supports Amazon editorial reviews and book descriptions for platforms like Barnes & Noble and Kobo, each with their own formatting rules built in.

How the Amazon Book Description Generator Works

This tool is designed to handle both writing and formatting (two areas that often trip authors up when publishing book descriptions).

The process is simple:

1. Choose your platform. Select where you plan to publish your description, such as Amazon, Amazon Editorial Reviews, Barnes & Noble, or Kobo. Each platform has different formatting rules, and the tool automatically adjusts what’s available based on your selection.
   
   
2. Enter your book description text. Paste in your existing description or draft a new one directly in the editor. If you’re copying from a word processor, paste without formatting to avoid hidden code that can cause publishing errors later.
   
   
3. Apply formatting options. Use the built-in controls to add bold text, italics, paragraph spacing, lists, or icons. Any formatting option that isn’t supported on the selected platform will be disabled, so you don’t accidentally use HTML that won’t be accepted.
   
   
4. Optionally improve your description with AI. If you want help refining your blurb, you can use the AI option to improve clarity, flow, and readability while keeping the description aligned with book-market expectations.
   
   
5. Generate your HTML code. When you’re satisfied with how everything looks, generate the formatted HTML code.
   
   
6. Paste the code into your publishing platform. Copy the generated code and paste it directly into the book description or editorial review field on your chosen platform.

This workflow ensures your book description is both visually clean and platform-compliant, without needing to write or troubleshoot HTML yourself.

What Platforms This Book Description Generator Supports

Different publishing platforms allow different formatting rules, which is where many authors run into trouble.

This book description generator is built to account for those differences automatically.

Amazon Book Descriptions

Amazon allows limited HTML in book descriptions, including bold text, italics, paragraph breaks, and certain list styles. This tool ensures your formatting stays within Amazon’s current rules so your description displays correctly and avoids validation errors.

Amazon Editorial Reviews

Amazon Editorial Reviews use a separate section from the main book description and follow their own formatting guidelines. The generator includes a dedicated option for editorial reviews, making it easy to format quoted reviews, blurbs, and endorsements without guessing which HTML is allowed.

Barnes & Noble Book Descriptions

Barnes & Noble supports a different subset of formatting options than Amazon. When you select Barnes & Noble, the tool adjusts automatically so you only see formatting choices that will display correctly on their product pages.

Kobo Book Descriptions

Kobo also has its own formatting rules for book descriptions. The generator adapts to Kobo’s requirements, helping ensure your description remains clean, readable, and properly spaced after publishing.

By selecting the correct platform before formatting your description, you avoid trial-and-error and reduce the risk of publishing errors or broken layouts.

Why Formatting Matters on Amazon

On Amazon, your book description is more than simple “copy.” It’s also structured content.

How your text is formatted affects readability, scannability, and whether your description is even accepted during publishing.

Amazon supports only a limited set of HTML tags in book descriptions. Bold text, italics, paragraph breaks, and certain list styles are allowed, while many common formatting options are not. If unsupported HTML is used, Amazon may strip it out, display your description incorrectly, or reject it entirely.

This is where many generic writing tools fall short.

They focus on improving the words, but they don’t account for Amazon’s formatting rules. The result is a description that may look fine in an editor, but breaks once it’s pasted into Amazon’s system.

Another source of confusion is grandfathered formatting. Some older books still display layouts that are no longer allowed today. Those descriptions continue to work because they were published before Amazon changed its rules. New descriptions must follow the current standards, which is why trying to copy the formatting from older listings often leads to errors.

This Kindlepreneur generator removes that guesswork by:

• Limiting formatting options to what Amazon currently accepts
• Preventing unsupported HTML from being used
• Producing clean, platform-compliant code ready for publishing

The goal? A book description that looks better and works.

Amazon Error: “Description May Not Contain Invisible Characters”

If Amazon shows an error message that says “Description may not contain invisible characters,” it means your book description contains invalid or empty HTML tags.

This usually happens when there are HTML brackets with nothing inside them, such as < > < >.

These empty tags are often introduced when text is copied from word processors or when formatting is removed improperly. While they may not be visible in the editor, Amazon detects them during validation and blocks the description from being published.

To fix the issue:

• Remove any empty or unused HTML tags
• Ensure all formatting elements contain actual text
• Re-generate your HTML using the tool before pasting it back into Amazon

Amazon tightened its validation rules in recent years, which is why some descriptions that once worked may now trigger this error. Cleaning out these invisible characters resolves the issue and allows your description to publish normally.

How to Publish Your Book Description on Amazon

Once you’ve generated your formatted HTML, you can publish your book description directly through Amazon Kindle Direct Publishing.

Publish Through Amazon KDP

1. Sign in to your Kindle Direct Publishing account.
2. Go to your Bookshelf and select the book you want to edit, or create a new title.
3. Scroll to the Description section.
4. Paste your generated HTML into the description field.
5. Click Save and Continue, then complete the remaining publishing steps.

After publishing, it can take up to 72 hours for the updated description to appear on the Amazon product page.

Alternate Method: Amazon Author Central

You can also edit your book description using Amazon Author Central.

1. Sign in to your Author Central account.
2. Select the Books tab at the top of the page.
3. Choose the book you want to edit.
4. Locate the Product Description section and click Edit.
5. Select Edit HTML, paste your generated code, and preview the result.
6. Save your changes once you’re satisfied.

Important note:

If you later update your book through KDP, Amazon may overwrite the Author Central description with the version stored in KDP. For most authors, editing the description directly in KDP is the more reliable approach.

How to Add Amazon Editorial Reviews

Amazon Editorial Reviews appear in a separate section from your main book description and are commonly used for endorsements, review quotes, or highlighted praise.

Create and Format Editorial Reviews

1. Gather short review excerpts from authors, publications, or reader reviews.
2. Enter each review on its own line in the generator.
3. Use bold, italics, or icons to style the text if desired.
4. Generate your HTML code once the reviews look the way you want.

Publish Editorial Reviews Through Author Central

1. Sign in to Amazon Author Central.
2. Open the Books tab and select the relevant title.
3. Scroll to the Editorial Reviews section.
4. Click Add, then choose Edit HTML.
5. Paste your generated code, preview it, and save your changes.

Editorial Reviews typically appear on the product page within 3 to 5 days.

How to Publish Book Descriptions on Barnes & Noble and Kobo

Once you’ve generated your formatted description, you can publish it on other retailers using their respective dashboards. While the steps are similar, each platform handles descriptions slightly differently.

Publish on Barnes & Noble

Barnes & Noble allows formatted book descriptions, but supports a different subset of HTML than Amazon.

1. Sign in to your Barnes & Noble publishing account.
2. Create a new book or select an existing title from your Projects dashboard.
3. Open the Book Details section.
4. Paste your generated description into the Default Book Description field.
5. Save your changes and continue through the publishing process.

Selecting Barnes & Noble in the generator ensures that only compatible formatting options are available.

Publish on Kobo

Kobo also supports formatted book descriptions, with its own layout rules.

1. Sign in to your Kobo Writing Life account.
2. From your dashboard, open the eBooks tab.
3. Select the book you want to edit.
4. Scroll to the Synopsis section on the “Describe Your eBook” page.
5. Paste your generated description and save your changes.

As with other platforms, choosing Kobo in the generator limits formatting to what Kobo currently accepts.

Advanced Formatting Tips for Book Descriptions

Formatting affects how easily readers can scan your book description, especially on long product pages. The generator gives you control over spacing, lists, and layout without requiring manual HTML.

Paragraph Spacing Options

There are two common ways to control spacing between paragraphs, depending on how compact you want your description to appear.

Standard Paragraph Spacing

When you press Enter at the end of a paragraph, the generator inserts spacing between paragraphs.

This approach works well when:

• Your description is longer
• You want clear visual separation between ideas
• Readability is the priority

The spacing will be preserved when the HTML is pasted into Amazon, Barnes & Noble, or Kobo.

Compact Paragraph Spacing

When you press Shift + Enter instead of Enter, the generator creates a tighter layout with no extra spacing between paragraphs.

This option is useful when:

• You want a more compact description
• You’re working with short, punchy sections
• You want to minimize vertical space on the product page

Using Bullet Points and Numbered Lists

Lists are helpful for highlighting features, benefits, or key takeaways in nonfiction descriptions.

Built-In List Formatting

You can create standard bullet or numbered lists using the Bullet List or Numbered List controls in the editor. These options generate platform-safe HTML automatically.

This is the simplest way to create clean, structured lists that display correctly after publishing.

Icon-Based Lists

For more visual flexibility, the generator also allows you to create lists using icons.

You can:

• Select an icon
• Add a line of text
• Press Enter or Shift + Enter to continue

This method allows you to build custom list styles that remain HTML-compliant while offering a different visual look.

Why These Formatting Options Matter

Amazon and other retailers restrict which HTML elements are allowed. Formatting that looks fine in a word processor or generic editor may break once published.

By using the generator’s formatting controls, you ensure:

• Your layout stays readable
• Unsupported HTML isn’t introduced
• Your description displays consistently across platforms
