Your child becomes the author. Lum is the AI narrator who listens, remembers, and makes the world real around every choice.
Your child speaks, types, or taps one of three story buttons that appear automatically. Lum is the narrator who listens and makes things happen. Silence works too - the world keeps moving on its own.
Every word, every tap, every pause is woven into the story forever. The world remembers why each choice was made and builds on everything that came before.
Parents set the rules of the world before the story starts. Lum follows them like the laws of physics - not as a filter that can be tricked, but as the actual structure of reality.
Every adventure is saved in your child's personal library. A collection of unique stories that no one else in the world will ever have - because no two children make the same choices.
Before the first word is spoken, you decide what kind of universe your family lives in. Lum makes those rules as real as gravity.
Cultural and religious values are baked into the world's physics. Stories can only grow within those roots.
Narratives scale in depth and consequence to match your child's age. The world grows with them.
Define the level of conflict the story can contain - from completely peaceful to age-appropriate adventure challenges.
Choose whether the story gently reinforces kindness, courage, honesty, or other values your family holds dear.
A story engine built different from the ground up.
Even while your child rests or sleeps, the world keeps living. Lum continues the adventure quietly until they return.
Your child can say something out loud, type a sentence, or tap one of three story buttons that appear automatically based on the current scene. All three options are always available.
Every story is created live, in real time. The world has never existed before and will never exist again. Completely unique to your child's choices, every single session.
Each world has characters and events that exist as possibilities waiting to be discovered. Your child might meet them, miss them, or change them completely. The story belongs to no one until your child walks into it.
"The best stories are the ones where you are the hero - where every choice you make shapes a world that will never be the same again."
The tellmeastory team
A glimpse of the adventures waiting to be born.
A world of ancient trees, hidden creatures, and a child who discovers they can speak to the wind. Every path chosen grows the forest differently.
Dive into a world of glowing fish and coral castles. A lost map leads somewhere different for every child who finds it.
History is never a dead end. Return to any past moment and explore what could have been - watch the story branch into a brand new path.
Smart enough to follow along. Gentle enough to let your child lead.
The story never freezes in waiting. It lives on its own - a perfect companion for bedtime or quiet moments. Lum keeps the world breathing until your child comes back.
No buttons. No menus. Just speak and the story shifts. Your child is not a player - they are the author. The world bends to their imagination.
Someone else's story. No choices, no impact. Forgotten by morning.
The world sits frozen until you press a button. Interaction without real imagination.
A world that listens, breathes, and remembers. Your child speaks, taps, or just watches - and the adventure keeps moving either way.
Designed for children aged 5–12, the engine automatically adjusts story depth to match each child's input. Younger children get simpler, warmer stories; older children unlock richer consequences and longer arcs.
tellmeastory runs in any modern web browser - no app download needed. Works on tablets, laptops, and desktops. A stable internet connection is required as the world is generated in real time.
Safety is built into the foundation, not bolted on top. No matter what a child types or says, the story engine cannot enter harmful territory. Parents set the world's rules and Lum enforces them like the laws of physics.
The early access version supports text input. Voice interaction (speaking directly to Lum) is in active development and coming soon.
tellmeastory is not a chatbot. Under the story layer is a structured world engine - a real memory of everything that has happened. Lum can only describe what the world's logic allows, so stories stay coherent and every choice has lasting consequences.
