Stuck on a math problem you refuse to give up on? Chiron writes the smallest hint on your page, just enough to keep you thinking, without spoiling the math. Write your working by hand. Chiron reads every line as you go and steps in only when it helps: a nudge when you're stuck, a question when you're close, a quiet check when you're not sure. It teaches. It never lectures. KEEP THINKING • Hints sized to the moment: the smallest push that keeps you moving • Get pointed at the slip, not handed the answer • Ask out loud, "where do I even start?", and talk it through DOES THE MATH PROPERLY • Every check is grounded in a real symbolic engine, so feedback is exact, never a chatbot's guess • Catches the sign you flipped, the solution you gained, the step that doesn't follow • Built for real work: algebra, trigonometry, calculus, ODEs, logs and more BRING YOUR OWN • Snap any problem with the camera and start working • Upload your notes and Chiron works from your course, not a generic one Best with an Apple Pencil. Chiron. Keep thinking.
