Characters that stay recognizable on every page
Most AI tools treat each illustration as a new image. SagaPages treats your protagonist as a locked identity — so kids still look like themselves from cover to last page.
Why one-off prompts fail for storybooks
Single-image generators optimize for one beautiful frame. A 12-page book needs the same hero in different scenes, angles, and lighting — without turning into a different child on page four.
- Hair, outfit, and face drift when each page is an independent text-to-image job
- Cast text in prompts is a soft hint — models still reinterpret the character
- Parents notice immediately; it breaks trust in personalized books
Identity Lock: photo in, consistent character out
Upload one clear photo. Pick one of 15 protagonist art styles. SagaPages builds a reusable character portrait and feeds it into every page through PuLID-based Identity Lock pipelines.
- Photo uploads are ephemeral — only the stylized portrait is kept after confirm
- Multiple providers with automatic failover if one vendor is unavailable
- Same pipeline for photo wizard protagonists and advanced library characters
Character Canon: structured anchors, frozen per book
Each character carries structured fields — species or role, body shape, signature features, default outfit, and consistency guardrails. When you start a book, a snapshot freezes that canon so later edits to your library do not change pages already generated.
- Main vs supporting cast with book-level snapshots
- Multi-character pages use compose → segment → inpaint when two or more characters share a scene
- Magic Editor lets you fix one page without redoing the whole book
New scenes without losing identity
Consistency does not mean duplicate poses. You can change location, action, and mood while keeping the same recognizable face and default outfit — unless you explicitly override outfit or expression for that page.
- Orientation chips tune age-appropriate vocabulary and theme
- 15 art styles map to curated book generation styles
- Per-page success billing — retry failed pages without paying for successes twice
Internal QA benchmark (updated quarterly)
We run fixed storybook scenarios—photo protagonist, multi-character cast, outfit change with explicit override, and style failover—to verify Identity Lock before shipping provider changes.
- 4 / 4 core QA scenarios passed in our latest internal run
- Likeness judged on face, hair, and default outfit stability—not pixel-perfect clones
- Failed pages can be retried per page; successes are not double-charged
Tips for the best photo reference
- Use a front-facing photo with clear eyes and minimal blur
- Plain backgrounds work best; busy scenes can confuse likeness
- One protagonist photo is enough to start — add library characters for siblings or pets
- Pick the art style early; cast flow auto-selects the matching book style
