HeyG Math vs SolvedBooks

Math usually isn't hard because you're bad at it. It's hard because steps get skipped, assumptions go unstated, and mistakes feel personal. Hey G works differently. Hey G helps you work through math problems one step at a time. You try a problem. G responds calmly — showing every step, explaining why it works, and helping you recover if you get stuck. No grades. No timers. No pressure. WHAT YOU GET Every course is a complete, structured curriculum — not random practice problems. Content spans Pre-Algebra through Calculus, with SAT, ACT, and GRE prep courses available. Your first course is completely free, forever. Pick any course in the catalog and it's yours — no credit card, no trial period, no catch. HOW IT WORKS - Pick a course and start at Chapter 1 - Work through problems at your own pace - Get clear, step-by-step explanations when you need them - G adapts to your level — quietly, without making it weird - Pick up exactly where you left off, every time WHO IT'S FOR Hey G is built for: - High school students working through Algebra, Geometry, or Trig - Parents helping with homework who need a refresher - Adults going back to school or preparing for standardized tests - Anyone who wants to understand why, not just get the answer AI TUTOR G is your personal math tutor. When you're stuck, G doesn't just give you the answer — G walks you through it, step by step, showing every operation and explaining every assumption. Your free course includes 5 AI tutoring sessions. Subscribe to AI Tutor ($12/month) for unlimited help across all your courses. COURSES AVAILABLE Foundation: Arithmetic, Fractions & Decimals, Ratios, Pre-Algebra Core: Algebra 1 & 2, Geometry, Trigonometry, Pre-Calculus Advanced: Calculus I & II, Linear Algebra Test Prep: SAT Math, ACT Math, GRE Quantitative WHAT MAKES HEY G DIFFERENT - No skipped steps. Every explanation shows each operation. - No hidden assumptions. G states what other resources skip. - No judgment. Mistakes are handled gently and used to help you learn. - No tricks. This isn't a game. It's a thinking partner. You don't need to be "good at math" to use Hey G. You just need to be willing to try. --- Subscription Information: AI Tutor is available as a monthly subscription for $11.99/month.

SolvedBooks is a free study companion for university and graduate students working through classic mathematics textbooks. Every solution is written from scratch by a working mathematician — not scraped, paraphrased, or copied from any publisher's solutions manual. Each exercise gets a complete worked proof in clean LaTeX, plus a brief final-answer summary. Currently covered — 1,400+ exercises: • Serge Lang — Undergraduate Algebra, 3rd Edition • Sheldon Axler — Linear Algebra Done Right, 4th Edition • John M. Lee — Introduction to Smooth Manifolds, 2nd Edition (GTM 218) • John M. Lee — Riemannian Manifolds: An Introduction to Curvature (GTM 176) How it works Question groups (5 exercises each) are locked by default. Tap "Watch ad to unlock" once per group and the unlock is permanent on your device. There is no in-app purchase to remove ads — the ads pay to maintain the app and cover more textbooks over time. What you will not find here • The original textbook problem statements — they are intentionally not reproduced • Hints, figures, or solutions copied from any publisher's manual • Accounts or cross-device sync — v1 is local-only and works offline Pen before Peek Please attempt each exercise yourself first. Productive struggle is where the mathematics lives. SolvedBooks is for the moments where you genuinely need a worked solution to keep moving forward, not a shortcut around the thinking. About the developer Built by Chris Pun, a math graduate working in differential geometry.
