How it works
No blank page. No awkward freestyling. Build a hero once and the platform writes a fresh, personalised episode every night with continuity, warmth, and a soft landing.
Step 01
Five short steps: looks, costume, a power, a weakness, and a catchphrase. Or hit "Surprise me" and the AI offers three to pick from.
Step 02
Theme, length, "had a hard day", or "scared of thunder tonight". Or just hit Tonight's story and we remember what you usually want.
Step 03
A calm reader fades the screen, a warm voice takes over, the moon pulses softly at the bottom of the screen. You tuck them in. The story ends itself.
Two modes, one hero
The same hero, the same memory, two completely different experiences. We do not blur them: bedtime is bedtime.
And as the stars watched quietly, Maya drifted into a peaceful sleep.
The saga
Every episode adds to a private library: a hero card, a growing entity registry of friends and foes, and an evolution timeline. Yes, Captain Echo really did befriend Luna the owl in episode four. No, the storm villain has not shown up since.

From parents
"The first thing in eighteen months that has reliably gotten Theo to sleep without three reruns of the same dinosaur book."

"My daughter writes her hero's catchphrase on her notebooks. She calls it her story now. That part I did not expect."

"The hands-free bit is the killer feature. I tuck him in, his eyes close, the screen fades. It just works."

Common questions
Bedtime Mode is hands-free and dims to a near-black moon screen 90 seconds in. Most parents start the audio, set the device face-down, and listen along.
After every episode we generate a structured summary: characters, places, and what changed for the hero. The next episode uses recent summaries plus pinned characters, so the world stays consistent.
We deliberately keep child data minimal: name, age, interests, and an avatar. It is encrypted at rest, with one-click export and deletion in account settings.
Yes. Child mode lets them pick a hero and theme. Story generation and account settings stay parent-gated with a four-digit PIN.
Build a hero in five minutes. The first three episodes are free.
