# Show HN: AI chat app build specifically for kids (howcomet.com) > Source: > Published: 2026-08-27 04:35:36+00:00 Every question you finish becomes a star in your own sky. Ask about volcanoes, keep a volcano. Free for 7 days, all of it. A grown-up's email to start, no card. A real answer, in the app. Not a mock-up. Volcanoes, black holes, why your ears pop. Say it or type it. The answer is written for your age. A quick game about what you just read. Get it wrong and it explains, then you try again. The star is yours. It fades if you leave it, and shines again when you come back. Rings, bars, orbits, waves. Pictures that move, so it makes sense at a glance. Stars group into constellations: animals, space, numbers. The ones you are forgetting go dim. A map of everything you have learned, one question at a time. Handing an AI to a child is a fair thing to worry about. Here is what we do about it. Before the tutor sees it. If one is refused, your child is told you will see it. And you do. Your password is never on the tablet, so your page cannot be opened from your child's device. No third-party analytics, not even fonts. Speech stays on the device, so your child's voice never leaves it. No coins, no packs, no chests. Stars are earned, never bought. Rewards are things you agree to in real life. Your week: what they asked, and what is slipping away. A chatbot answers and forgets. Howcomet answers, checks your child understood, and keeps it. After a month they have a map of what they know, and you can see what is fading. It can, and we would rather say so. But the games and pictures are not invented by the AI. We built those, and anything that does not check out is thrown away instead of shown. Your weekly page lists what your child asked, so you can see it for yourself. Less than you would expect. There is a daily limit on what a child can earn, so playing longer does nothing. Stars come back to life by coming back tomorrow. One grown-up account, a sky each. Their own stars, their own reading level, their own goals. Nothing crosses over. It stays. They can still look at everything they built, they just cannot ask new questions. Months of a child's work should not disappear because a card expired. Free for 7 days. A grown-up's email is all you need to start.
