Tutor Kay (just "Kay" to her students) is an AI math tutor built by Ms. K, a former California high school math teacher. Kay teaches the way a real human tutor does — patient, encouraging, and never giving you the answer before you've tried. WHAT KAY DOES - Walks you through any math problem step-by-step, with hints instead of solutions - Explains concepts from counting through topology in plain English - Takes you through full SAT Math practice tests with real exam timing (22 questions, 35 minutes) - Shows your accuracy by topic so you know exactly where to focus - Renders math properly (LaTeX), draws diagrams, and even reads questions aloud - Accepts photos of your handwritten work — show Kay what you tried BUILT FOR REAL STUDENTS Kay is free. There's no signup wall. There are no ads. There's no email harvesting. Just open the app and start learning. If you want your progress to sync across devices, you can set up a passkey account — your data is tied to a random nickname like "purple-tiger-7421," never to your real identity. 5 FULL SAT MATH PRACTICE TESTS Each test mirrors the real Module 1 mix: Algebra, Advanced Math, Problem-Solving & Data Analysis, and Geometry & Trigonometry. Diagrams are embedded right in the question. The timer matches Bluebook. Your score breaks down by domain so you know exactly what to study next. WHO BUILT THIS Tutor Kay was built by Radhika Kolachina, a former CA math teacher who wanted every student to have access to a patient, encouraging tutor — not just the ones who could afford one. Kay is the AI tutor she wished her own students had. PRIVACY Kay doesn't ask for your name, your email, or anything else to use her. Chat messages aren't stored on Kay's servers — only in your own browser. Read the full privacy policy at tutorkay.ai/privacy. Questions, feedback, or just want to say hi? Tap "Send feedback" inside the app. Ms. K reads every message. — K
