Geometry AI Solver & Scanner

Features
Read full description

Geometry AI Solver turns your phone into a step-by-step geometry tutor. Snap a photo of any problem — a triangle, a circle, a coordinate plane, or a hand-drawn diagram — and get a clear, worked solution with every step explained. SCAN ANY GEOMETRY PROBLEM Point your camera at a homework question or textbook page. The AI reads the diagram and the text, identifies the shape and the given measurements, and solves it the way a great teacher would: one labeled step at a time, with the theorem behind each move. STEP-BY-STEP SOLUTIONS YOU CAN LEARN FROM No black-box answers. Every solution shows the reasoning — the Pythagorean theorem, similar triangles, the Law of Cosines, inscribed angles, area and volume formulas — so you understand how to do the next one yourself. A COMPLETE GEOMETRY COURSE Beyond the scanner, work through a guided curriculum of 40 topics across 8 units: - Foundations: points, lines, planes, segments, angle pairs - Angles & Lines: parallel lines, transversals, two-column proofs - Triangles: congruence, the Pythagorean theorem, isosceles & equilateral - Quadrilaterals & Polygons: parallelograms, interior/exterior angles, similarity - Circles: arcs, inscribed angles, tangents, equations of circles - Area, Surface Area & Volume: polygons, sectors, prisms, cones, spheres - Coordinate Geometry: distance, midpoint, slope, coordinate proofs - Transformations & Trig: reflections, rotations, right-triangle trig (SOH-CAH-TOA), Laws of Sines & Cosines Each topic includes a clear explanation, worked examples, and a quiz to lock it in. ASK THE AI TUTOR ANYTHING Stuck on a concept? Chat with a geometry tutor that explains in plain language, gives hints before answers, and adapts to where you are. BUILT FOR REAL STUDENTS - Middle school through high school geometry - Perfect for homework, test prep, and the SAT / ACT - Track your progress, earn XP, and keep a streak going - Works for clean textbook scans, photos, and hand-drawn figures WHY GEOMETRY AI SOLVER Most math apps try to do everything. We do geometry — and we do it deeply: a real curriculum, a tutor that knows the subject, and a scanner tuned for diagrams, not just equations. Download Geometry AI Solver and turn every geometry problem into a lesson you understand. — Premium unlocks unlimited scans, the full AI tutor, and the complete topic library.
