When your child asks a why-question, Whyzard gives you two layers, side by side — a calm, kid-friendly answer you can read together, and a real adult-level explanation underneath. So you're not reciting; you're learning alongside them. HOW IT WORKS • Type or speak any question your child has asked, or one you're both curious about: "Why is the sky blue?" "Why can birds fly?" "Why can't I have ice cream before dinner?" • Get a two-layer answer in seconds — a kid-friendly framing first, your own deeper layer underneath. When a "why" is really about a rule or a feeling, Whyzard tells you so and gives you one calm answer instead of two. • The kid-facing answer, read aloud. • An honest note flags what the answer leaves out, and when your child will be ready for that next layer. • Follow-up suggestions help you go deeper if either of you stays curious. • After each answer, a few open-ended questions to ask your child back — each with a quick answer ready for you. • A starter question every day, in case you want a fresh question to explore together. LEARN TOGETHER, IN TWO LAYERS The for-your-child layer is the words you can read aloud together — tuned to how your child takes in ideas, from first plain-spoken explanations to a well-read kid ready for bigger words. Set your child's level once, and every answer comes back fitted to them. The just-for-you layer is a real explanation written for the parent — as deep as you want, from a quick gist to the full mechanism behind it. You and your child learn together, instead of you relaying a script you don't fully understand. BUILT FOR CURIOSITY — LEARNED TOGETHER The why-questions kids ask all day — about sky, weather, animals, space, bodies, dreams, why things work the way they do. Each one becomes a moment to wonder about together. WHY IT'S NOT ANOTHER CHATBOT • Built for two readers, not one. Open it with your child — answer on screen, conversation in the room. • No account, no sign-up, no waiting. Open the app, ask, read together. • Your conversation history stays on your device. SIRI-READY "Hey Siri, ask Whyzard why the sky is blue." A calm answer comes back on screen. ASK IN ANY LANGUAGE Whyzard auto-detects the language of each question and answers in the same language. — Whyzard is for the questions kids ask and parents don't always have words for. Open it together. Read it together. Keep wondering together. — WHAT'S FREE, WHAT'S PLUS Free includes five questions a day, one child profile, and a daily turn with the premium read-aloud voice. Whyzard Plus lifts the daily limit, makes room for up to five children, and opens the premium voice for everyday reading. — Whyzard Plus is an auto-renewable subscription.
