An all-in-one solution for image accessibility in Ebooks.

Our Story

The Free Ebook Foundation envisions a world where Ebooks will be funded, distributed and maintained for the benefit of all, by coordinating the efforts and resources of many.

Many projects, such as the Gutenberg Project and, have made great progress in distributing Ebooks. However, many of these Ebooks lack alternative text (alt-text) for their images, making them inaccessible to those using screenreaders.

There are about 470,000 images without alt-text in the Gutenberg Project's collection alone.

The Solution

Alt-Gen is a software designed to scan through Ebooks and generate captions for images lacking quality alt-text.

We utilize various modern technologies to accomplish this, such as Image Caption AIs, Optical Character Recognition, and Large Language Models.
