A personalised book where the child on page 12 is still the child on page 1
Generating one good picture of a child is easy. Generating forty that are recognisably the same child is the actual product, and it is the part parents notice. KokoWorlds is in build.
In build — tell us what you need and we will say honestly how close it is.

Why this exists
Personalised children's books either swap in a name over stock art, or use AI that redraws the child slightly differently on every page. Parents notice immediately, and a keepsake that does not look like their child is not a keepsake.
A photo becomes a character, the character becomes a story, and the story becomes a printable book. The hard part is not generating a picture of a child — it is generating forty of them that are recognisably the same child.
What it does
Everything KokoWorlds handles for you.
Appearance lock
One master render is described in an immutable paragraph that every later page is generated against, so the face does not drift between illustrations.
Six-view turnaround
The character is rendered from six angles before any page is drawn, which is what lets later scenes place them anywhere without redesigning them.
Story and page direction
The narrative is written first, then split into per-page image prompts, so the illustrations follow the story instead of the story being retrofitted to stock art.
Print-ready output
Line art is vectorised and laid out as a press-ready PDF, not a folder of PNGs the parent has to deal with.
What you get
Concretely, what lands.
Not adjectives — the things that exist afterwards that did not exist before.
- One master render, described in an immutable paragraph that every later page is generated against — so the face does not drift.
- A six-angle turnaround produced before any page is drawn, which is what lets later scenes place the character anywhere.
- A press-ready PDF with vectorised line art, not a folder of PNGs a parent has to deal with.
How it works
From nothing to working.
Lock the character
A photo becomes one master render. That render is described in a paragraph that is then immutable — every later illustration is generated against the description rather than against the previous image, which is what stops drift compounding.
Turn them around
The character is rendered from six angles before the story is illustrated. Later scenes can put them anywhere without redesigning them on the spot.
Write, then direct
The narrative is written first and only then split into per-page image prompts, so the illustrations follow the story instead of the story being retrofitted to whatever the model produced.
Set it for print
Line art is vectorised and laid out as a press-ready PDF.
Who it's for
Built for these people.
If you are not one of them, we will say so rather than sell you a seat.
- Parents and grandparents buying a keepsake rather than a novelty
- Gift buyers at births, birthdays and first days of school
Before you ask
The questions that come up.
Not yet — KokoWorlds is in build. Tell us you want one and we will come back to you when it opens, rather than take money for something that is not finished.
A customer's photographs are not ours to keep. Photos of real people never enter our source control, and retention is scoped to producing the book. If that is not good enough for you, say so before you upload anything.
Most of them swap a name over stock art, or use AI that redraws the child slightly differently on every page. The appearance lock and the six-view turnaround exist specifically to solve the second problem.
The output is a press-ready PDF with vectorised line art, which is what a printer needs. Print fulfilment itself is a separate question we are still answering.
