Project Gutenberg ↗Who is this person? Where are we? What has changed? Book Codex brings together characters, places and details from analysed scenes — and gives your illustrations a story to follow.
See yourself in the storyIllustrative character card
Fictional example, not an analysis of a published book. Real cards may have missing details.
Personalisation changes image instructions. It does not rewrite the book or its recorded facts.
Open character and place cards to revisit the details discovered so far.
View the context for a selected scene. Cards grow as more of the book is analysed.
Adjust a character’s appearance or a place’s description. Your choices are stored separately from book facts.
Scene details guide illustration requests; known character profiles can also inform AI voice selection.
Book evidence and contextual inferences are labelled separately. Missing information remains visible as unknown.
Choose a character in Book Codex, add your photo and create an illustration with your own visual casting. The scene still supplies the setting, clothes and action unless you change them.




AI-created demonstration with fictional adults. These are illustrative examples, not captures from the app; generated likeness and scene details can vary.
Open Book Codex and select a character in the scene.
Use the camera or gallery, then choose where your change applies.
Request a new image with your saved choices and the selected style.
In the app: Book Codex → character → photo → create an image
Adding a photo does not generate an image. The app shows the applicable cost and asks for confirmation before creating a new illustration.
Choose a visual direction while SagaBook keeps the scene and revealed book context consistent.
