How it works

A bedtime ritual that takes thirty seconds to start.

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.

  1. Step 01

    Build a hero, together

    Five short steps: looks, costume, a power, a weakness, and a catchphrase. Or hit "Surprise me" and the AI offers three to pick from.

  2. Step 02

    Pick tonight's mood

    Theme, length, "had a hard day", or "scared of thunder tonight". Or just hit Tonight's story and we remember what you usually want.

    CourageSharingFriendshipTonight's mood
  3. Step 03

    Let it play, hands-free

    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

A calm wedge for sleep. A bright world for play.

The same hero, the same memory, two completely different experiences. We do not blur them: bedtime is bedtime.

As the sun dipped below the hills, the hero and a loyal owl friend climbed to the top of the quiet mountain. The stars were waking up, one by one…

And as the stars watched quietly, Maya drifted into a peaceful sleep.

Bedtime mode

Slow, warm, ambient.

  • Single column, calm reading rhythm
  • Warm amber on deep indigo
  • AI voice at 0.9x with paragraph fades
  • Ends with a personal closing line

Hero builder

A hero who looks the same in episode 1 and episode 30

Describe them in one sentence or build them step by step. We lock in their look with a reference sheet, so every illustration feels like the same friend.

The saga

A world your child comes back to.

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

Quieter bedtimes. Bigger imaginations.

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

Sara, mum of two

Bristol

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

Anais, dad

Lyon

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

Mike, single dad

Common questions

Things parents ask us first.

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.

Tonight, try a quieter bedtime.
