Install the Chrome extension

It fills Amazon KDP's eBook pages with your book: the details, the categories, the AI answers, the files and the price. You check each page, and you press Publish yourself. The extension never does.

Before you start

• A computer with Google Chrome. Phones and tablets cannot run Chrome extensions.
• An Amazon KDP account at kdp.amazon.com, with your tax and payment details complete. Sign in to it in the same Chrome.
• Sign in to brains.biz in the same Chrome.

Install it

1. Download the extension

   Download Brains.biz Publisher

2. Unzip it

   On Windows, right-click the file and choose "Extract All". On a Mac, double-click it. You get a folder. Keep it where it is: Chrome loads the extension from it.

3. Open Chrome's extensions page

   Type chrome://extensions in the address bar and press Enter.

   Copy the address

4. Turn on "Developer mode"

   The switch is at the top right of the extensions page.

5. Press "Load unpacked"

   Choose the folder you unzipped, the one that holds the file manifest.json.

6. Pin it

   Press the puzzle piece next to the address bar, then the pin next to Brains.biz Publisher.

7. Publish a book

   Open your book on brains.biz and reload the page. "Publish on KDP" now opens KDP in a new tab and fills it page by page.

If something goes wrong

Press "Get help" in the extension's panel on the KDP page; it sends us what happened on that page. You can also use "Share my screen with support" in your account menu, so we can see it with you. You can always upload the files by hand: on your book page, press "Upload by hand".
