How it works
From page to picture, in three steps.
Open your book
Add a book from your device, or pick one from our library. Nothing to sync — Ridio reads it directly.
Ridio follows the story
As you read, it identifies characters, places and each page's most visual moments.
Every moment, an illustration
It generates images consistent with what it already knows about the book, in the style you pick.
Everything your book deserves
Ridio doesn't replace your imagination — it keeps it company.
Characters with a face of their own
Every character keeps a consistent look every time they appear.
A map of every relationship
See how your characters connect — alliances, rivalries and family ties, at a glance.
Places that come alive
The story's settings get illustrated so you can picture them more clearly.
“The sea roared beneath the storm as Elena ran toward the lighthouse.”
Automatic standout scenes
Each page is scanned for its most visual moments, ready to illustrate with one tap.
