Everything You Get

Alt Text for Every ImageDIY: 3–10 hours
Every image in your book gets a thoughtful AI-written description. You could write alt text yourself in Markua — we make that as easy as possible, but describing every image by hand still takes 3–10 hours of your time.
In Your Book's Own Language
Alt text is written in your book's own language — a German book gets German alt text. It works for every book you can write on Leanpub, not just English ones.
Invisible Everywhere Else
The alt text makes your ebook work with screen readers and supporting ebook readers. It doesn't appear in the print book or change how your ebook looks.
Tracked, Reviewable, Editable
Every change is recorded as a tracked version, so nothing is ever lost. You can review exactly what was added, and edit any description you'd like to improve.
Fully Automated, Starts Immediately
No calls, no waiting for a quote. AccessibilityAI starts the moment you buy, and we email you as soon as it's done — typically within the hour.

Who Is This For?

  1. AccessibilityAI is for authors who want their book to be accessible to readers with visual disabilities, without spending days writing alt text for every image by hand.
  2. It adds AI-generated alt text to every image in your book, written in your book's own language. You can review and edit every description afterwards — it's your book.

What Does AccessibilityAI Do?

  1. AccessibilityAI is fully automated. When you purchase it:
    1. We read every image in your book's manuscript, in context — the AI sees the surrounding text, so a diagram gets described as what it explains, not just what it looks like.
    2. We write descriptive alt text for each image and add it directly to your manuscript.
    3. We generate a fresh preview of your book and email you when it's ready to review.
  2. The alt text makes your ebook more accessible to readers with visual disabilities who use screen readers or supporting ebook readers. It's invisible everywhere else — it doesn't appear in the print book or change how your ebook looks.
  3. Every change is recorded as a tracked version, so nothing is ever lost — you can review exactly what was added on your book's versions page, and edit any alt text you'd like to improve.

AccessibilityAI is Only $49

  1. AccessibilityAI is just $49. We want the price to be both simple and affordable.
  2. (If you choose a book which is over 200,000 words, there is an extra charge of $1 per 1,000 extra words. However, almost all Leanpub books are shorter than that, so chances are this doesn't apply to you.)

How Long Does It Take?

  1. AccessibilityAI typically takes less than an hour, depending on how many images your book has. We email you as soon as it's done, and a fresh preview of your book starts building automatically.

Frequently Asked Questions

Why Did Leanpub Build This?

  1. Ebooks should be for everyone. Most authors agree — but writing good alt text for dozens of images is exactly the kind of careful, repetitive work that never makes it to the top of the to-do list. AccessibilityAI does it in one click, and you keep full editorial control afterwards.

Does It Work for Books in Any Language?

  1. Yes! Alt text is written in your book's own language — a German book gets German alt text. (This is different from IndexAI, which is English-only.)
