What does 'reflowable text' actually mean for an ebook?

Reflowable text means the content automatically adjusts to fit the screen size, font choices, and reading settings chosen by the user. Unlike a fixed-layout ebook (like a children's picture book), reflowable text ensures your book remains readable and looks good no matter the device or how the reader prefers to consume it.

Can AI *completely* automate ebook formatting now?

AI can automate a significant portion of the complex coding required for strong reflowable ebooks. However, human review and testing on actual devices are still essential to catch subtle rendering issues and ensure a polished reader experience. It's a powerful tool for automation, but not a full replacement for human quality control.

Will this make my old ebooks look better?

This automation focuses on generating new ebooks with superior formatting from the outset. While the principles of semantic HTML and resilient CSS can be applied to existing files, it often requires a manual refactoring process rather than a simple re-export. The benefit is for future publications.
