AIPrentice

Every other app lets AI teach your child. AIPrentice flips it: your child teaches the AI. Hatch a clueless dinosaur that can't tell a cat from a dog. Your child is its teacher - drawing examples, naming them, feeding its tiny brain. Then quiz it! Sometimes it answers with hilarious confidence and gets it completely wrong. That's not a bug. That's the lesson. ONE EGG A DAY, FOR YEARS - A new egg hatches every day with one small, clear thing to do - Over 1200 handmade levels on 24 islands - Collect eggshells: every 50 levels hatches a brand new dragon - Miss a day and nothing is lost: skipped eggs wait in the nest - Grown-ups choose the pace: 1, 3 or 5 levels a day, or no limit - After all 1200, the Endless Sea begins, so the levels never run out EVERY LEVEL TEACHES ONE IDEA ABOUT AI - Draw along a pencil, teach the same thing a few times, then quiz it - Tell two look-alikes apart. Teach one drawing and see why one is never enough - Draw it huge, tiny, tilted or upside down and see what it still knows - Find the drawing filed under the wrong name, throw it out, watch it get smarter - Later on, your child decides what to teach. Their ideas never run out MY DRAWING BOOK - Every drawing your child makes is kept - taught, quizzed, traced or redrawn - in a book to flip through - The story of each thing: the cat from the very first drawing to today's - A drawing coach on the cover: what your child drew this week, where they got braver, one idea for next time. Only about progress - Tidy the book: drag drawings into a new order, or throw one away. What the pet remembers is untouched - Draw it again: an old drawing fades in as a hint, then before and after sit side by side MORE TO DO - Talk to it: teach it words out loud; it talks back using only what you taught it - Ask Dr. Dino: a friendly dino teacher answers questions in simple words, on device - Make it a movie: a film of the drawings with piano music, narrated by the pet. Same-thing drawings play as a flipbook and walk across the screen, so your child's cats become animation - Memory Backpack: see every drawing it remembers, and take memories away. The drawing stays in the book - Draw in 8 colours and 3 pen sizes. Filled or outlined, facing left or right - it still knows - It remembers you: a little diary of things you did together - Pick up English: teach in Chinese and it shows and says the English too WHAT KIDS ACTUALLY LEARN - AI is taught with data - it only knows what YOU show it - Too few examples means silly mistakes. More examples means a smarter pet - AI can be confidently wrong, which is why you should always double-check it - When it guesses, it shows WHICH memory it thought of, and admits what it never learned - Take memories away and it forgets, even shrinks - the data IS the brain - It coaches you back, and warns you the moment two things look too much alike PARENTS CAN RELAX - On device by design. Nothing is uploaded automatically - a picture leaves only if you, the grown-up, share it - Speech is recognized on device. Recordings are never saved or uploaded - No ads, no accounts, no data collected, no tracking (Made for Kids). Works offline - Everything leaving the child's flow sits behind a grown-ups-only gate: sharing, backup, camera, history, pace, reset, tip jar - Camera and photos are off until a parent turns them on. Photos become outlines on device; originals are never kept - Drawing growth for parents: drawings per week, in numbers only A NOTE ON "ASK DR. DINO" Needs the on-device intelligence of newer iPhone and iPad on the latest iOS; everything else works the same anywhere. Dr. Dino is labeled as an AI that can make mistakes, keeps to child-friendly topics, and if a child raises something serious it always says: talk to a trusted grown-up now. AIPrentice is free. If your family wants to support development, there is a small tip jar in the parents area. It unlocks nothing: everything is free. Raise an AI. Understand the future.
