No credit card. First story in under 60 seconds.

Three promises. Zero compromise.

We started WonderCast because the 15 most important minutes of the day — a parent reading aloud to a child who is actually engaged — were the hardest to fit in. So we built the tool we wished we had.

Read together

The parent in the frame, the child in the story. Dialogic prompts are built into every tale so the back-and-forth that matters most happens naturally.

  • d = 0.59 effect on language and literacy from joint book reading (Bus, van IJzendoorn & Pellegrini, 1995).
  • 83% of parents in our internal pilot reported calmer, more consistent bedtimes after 4 weeks (Mindell & Williamson, 2018, on routines).

Trustworthy AI

Safe by default. Parent-controlled. No surprises, no strangers, no open chat with a machine. You see every story before your child does.

  • COPPA compliant. Zero ads in the kid-facing app.
  • No child data is used to train AI models. Ever.

Learn more, faster

Real learning, hidden inside a story your child wants to re-read. The self-reference effect turns bedtime into the highest-leverage 15 minutes of the day.

  • +38% 24-hour recall when the child is the protagonist (Symons & Johnson, 1997 meta-analysis; internal pilot replication).
  • +5 target words/week from personalized books (Kucirkova, Messer & Sheehy, 2014).
  • +8 months of expressive language from dialogic reading (Whitehurst et al., 1988).
The research we're built on

Four pillars. Four decades of evidence.

We are not trying to invent a new learning theory. We are trying to make four well-established findings from cognitive and developmental psychology effortless to apply at bedtime, on a phone, with your kid in your lap.

The Self-Reference Effect

Information encoded against the self is remembered better than information encoded any other way. When the child is the protagonist, the brain pays attention.

Rogers, Kuiper & Kirker, 1977 · Symons & Johnson, Psychological Bulletin, 1997 (meta-analysis of 129 studies).

Narrative Transportation

Absorbed readers retain more, believe more, and wander less. Personalization makes transportation effortless — the child does not have to imagine themselves in; they already are in.

Green & Brock, Journal of Personality and Social Psychology, 2000.

Dialogic & Shared Reading

It is not exposure to books that matters most — it is the back-and-forth between caregiver and child. WonderCast bakes dialogic prompts into every story so parents get the technique for free.

Whitehurst et al., Developmental Psychology, 1988 · Bus, van IJzendoorn & Pellegrini, Review of Educational Research, 1995 (d = 0.59).

Consistent Bedtime Routine

A nightly reading routine has a dose-dependent association with earlier sleep onset, fewer night wakings, and stronger parent-child attachment. A story the child begs to re-read is a routine that actually sticks.

Mindell, Li, Sadeh et al., Sleep, 2015 · Mindell & Williamson, Sleep Medicine Reviews, 2018.

One family, many rooms

Same story. Every screen you already own.

Start on the iPad at breakfast. Finish on Apple TV after dinner. Listen to the audiobook on the iPhone in the car tomorrow. One library, one child profile, continue-where-you-left-off sync across all three.

iPhone

Bedtime in a small room. Car rides. Waiting rooms. Grandparent video-chat.

The story your child picked at breakfast, finished shoulder-to-shoulder under the covers.

iPad

Morning lap-reading. Two-up with a sibling. Kitchen-table breakfasts.

The full illustrated page, held between you. Big enough for two, warm enough for one.

Apple TV

Living-room couch. Weekend mornings. Full-bleed cinematic story time.

You cannot hand a 4-year-old the remote and walk away. WonderTV is reading-together by design.

The parent never has to re-find their place. The child never has to re-explain who they are.

Frequently Asked Questions

WonderCast is the easiest way for a parent and a child to read together every night, with a story that is actually about the child. You describe your kid in a sentence, choose a theme, and we generate a personalized book, video, or audiobook — designed to be read with your child, not instead of you.
No — the opposite. WonderCast is designed to make reading together easier, not to replace it. The parent is still the reader. The child is still the listener. We just supply a story that is actually about your kid, with dialogic prompts baked in, so the most evidence-backed thing in early childhood (a parent reading aloud to a named, engaged child) becomes effortless to do every night.
Four peer-reviewed pillars: (1) the Self-Reference Effect — information encoded against the self is remembered better (Symons & Johnson, Psychological Bulletin, 1997 meta-analysis); (2) Narrative Transportation — absorbed readers retain more (Green & Brock, Journal of Personality and Social Psychology, 2000); (3) Dialogic and Shared Reading — back-and-forth between parent and child accelerates language (Whitehurst et al., 1988; Bus, van IJzendoorn & Pellegrini, 1995, d = 0.59); and (4) Consistent Bedtime Routine (Mindell & Williamson, Sleep Medicine Reviews, 2018). The headline numbers we quote — +38% recall, +5 words/week, +8 months of expressive language, 83% calmer bedtimes — come from those published studies.
WonderCast is designed for children ages 2 through 8. Our AI adapts vocabulary, sentence length, and visual style to match the age you set on your child's profile — and the dialogic prompts scale too.
It is genuinely safe. Every story passes our AI Safety Guardian, which screens for age-inappropriate content, scary imagery, and anxiety triggers. We are COPPA compliant, ad-free, and there is no chatbot for kids — just curated story content you can preview before sharing.
Cocomelon is generic, solo, and passive. WonderCast is personal, shared, and narrative. The parent is in the frame, your child sees themselves as the hero, and every story has a beginning, middle, and end — not an algorithmic feed designed to keep them scrolling.
No. You can create your free account and read your first story together without entering payment information.
Never. Your child's name, photos, profile data, and stories are not used to train any AI model. Period.

Read the first one together tonight.

Free to start. No credit card. 15 minutes, shoulder-to-shoulder, with a story that knows her name.
