The Cursus difference
One choice, and the next chapter is written down that route.
Experience it yourself. Read the end of Chapter Three below, and make a choice to see how the story adapts instantly.
Chapter Three
The lantern guttered as Wren reached the split in the tunnel. Behind her, the tide was already climbing the steps one by one. Two passages waited in the dark — one breathing cold salt air, the other dead silent.
What happens next?
Two ways to read
Two reader tracks, the same choice-led engine.
For your children
Age-appropriate stories where children choose between two next steps and see their route unfold. Junior and Family plans keep parents in control.

From a blank page to a story path of their own.

Cursus plans and writes a story shaped around them — and illustrates it for the youngest readers.
Choose the course.
At each chapter's end, the reader picks between two paths and the story continues from there.
What makes a Cursus book
Not just personalised. Participatory.
We don't just insert a name into a pre-written template. Our engine crafts a living, breathing world that reacts to the reader's decisions at every turn.
Start reading nowTwo choices at every chapter
The reader chooses the next step before reading on, so the story keeps responding to them.
A route no one else has taken
Names, age, genre, and choices combine into a course through the book that belongs to that reader.
Age-aware writing rules
Tone, length, vocabulary, and themes adjust to the chosen age band — guardrails are not optional.
Character-consistent illustrations
For ages 2–4, every page features the same characters drawn the same way, with style references that travel.
Web and mobile
Reading position, bookmarks, and the visible reading path stay in sync across all your devices.

Reading position, bookmarks, and the route taken so far stay in sync. Begin a chapter on the sofa, then choose the next path on the train.

Built with parents in the room.
We believe interactive reading should be a safe space. Our platform is designed from the ground up to give parents complete peace of mind.
Age-appropriate by design
Each book follows strict writing rules for its age band — vocabulary, length, themes, and tone are bounded.
Parents in control
On Family and Junior plans, parents see the age band each child reads at and can review every book on a child's account.
A safe, ad-free space
Every story and illustration lives inside Cursus. There are no adverts, no outside links, and nothing pulled in from elsewhere.
