Play Heidi — an interactive story where YOU are the hero

after the classic by Johanna Spyri, 1880

Climb to the Alm-Uncle's hut and win over the gruffest man in the Alps. Run the high pastures with Peter and the goats, then get carried off to Frankfurt — and find a way back to the mountains for yourself and for Clara.

A moment from one playthrough

Fräulein Rottenmeier has locked the window. Beyond the glass there are only roofs — no fir trees, no wind, and the white rolls you've been hiding for Grandmother are found and confiscated. Klara watches you, worried. Plead your case at dinner, or plan the journey home tonight?

Live Heidi, don't just read it

In this interactive telling of Heidi, you don't read about the hero — you are the hero. The Storyteller keeps Johanna Spyri's world true to the original — its characters, its places, its mood, all held as canon — then narrates every scene aloud and draws the moment you're in as an ink illustration. You type or speak what you do next, and the world answers: it remembers the promises you made, the things you took, and the people you crossed. Follow Johanna Spyri's plot faithfully, or step off it and watch a brand-new version of Heidi unfold — one that still reaches a real ending.

How it works

The Storyteller holds the world of the book as canon — its characters, places and mood — and opens with you as the hero.
Type or speak anything: the world reacts, remembers, and stays true to the original's spirit.
Every playthrough is a brand-new story. Follow the plot — or break it and see what happens.
