Accessible structure
Build books with clear headings, sections, navigation, tables, lists, citations, and reading order.
Codal checks that the structure is understandable to both readers and assistive technologies.
Accessibility
Make books easier for everyone to read.
Codal helps authors and publishers create accessible books from the beginning, identify problems before publication, and clearly describe the accessibility of every edition.
Images with useful descriptions
Images require alternative text before a public edition can be published.
Authors can add descriptions while uploading media, review them in context, and update them as the book changes.
Languages and reading systems
Codal supports multilingual books, right-to-left languages, vertical writing, ruby text, and language information at the book and page level.
This helps reading software interpret and present the content correctly.
Accessible formats
Create accessible EPUB and PDF editions from the same source used for the web and print versions.
Codal runs format and accessibility checks before public release.
Problems you can fix
Accessibility findings appear where the work happens-not only at the end of publishing.
Codal points to the affected page or content, explains the issue, and provides a direct way to fix or assign it.
Clear information for readers
Every published edition can include an accessibility summary describing its navigation, image descriptions, reading modes, and available formats.
Readers can understand what the book supports before downloading it.
Publish books everyone can read.
Create something new, import an existing manuscript, restore an older work, or help improve an open edition. Codal handles the publishing process so you can focus on the book.
