GeometrAI

GeometrAI is all of high-school geometry, made visual. LEARN EVERY TOPIC 136 topics, from points and angles to proofs, transformations, similarity, trigonometry, circles, area, volume and probability. Each one starts with the key idea in plain words and a figure you can drag: move a point and watch the angles, lengths and areas change while the rule stays true. SEE WORKED EXAMPLES Swipe through fully worked examples, step by step, with the figure drawn to scale. PRACTICE WITHOUT LIMITS Every topic makes new problems as long as you want to keep going. Type your answer the way you'd write it (5√2, 12π, 3/8, 40°), get it checked instantly, and see every step of the solution. DRAW AND MEASURE The Sandbox is a blank page with points, lines, circles, polygons, angles, midpoints, perpendiculars and parallels — and everything is measured live. A TUTOR THAT SHOWS, NOT TELLS (optional) Type a problem or take a picture of a worksheet, and the tutor works it out on the figure: highlighting parts, drawing the construction, animating dilations and rotations, and writing the math line by line. It speaks only in sentences from the app's own reviewed phrasebook, and the app checks its arithmetic. When it's done, practice more problems just like it. Share a lesson with a friend as a file they can open in GeometrAI. The tutor uses an AI service of your choice (xAI Grok, OpenAI or Anthropic Claude) with your own API key, added by a parent in Settings. Everything else works offline with no account. PRIVATE BY DESIGN No accounts, no ads, no tracking. Progress stays on your phone.
