Stuck on homework? Scan a problem—or type it—and get step-by-step help, not just a final number. AI Homework Helper is a study tool for math, science, English, and more. Photograph a worksheet or textbook page, crop the question, and receive a clear overview, numbered steps, and a Final Answer you can review before class. HOW IT WORKS 1. Scan or type your question 2. Pick your subject and explanation level 3. Read the solution, copy it, or save it to History FEATURES STUDENTS USE MOST • Homework scanner – Camera and photo library; crop the problem so the AI reads exactly what’s on the page. • Subject modes – Math, Science, English, History, Social Studies, World Language, Computer Science, and more—answers match the class you’re in. • Explanation levels – Brief, Standard, or Explain like I’m 12—same question, depth you choose. • Step-by-step solutions – Structured overview, clear steps, and a dedicated Final Answer section (great for algebra, chemistry, physics, and test-style questions). • Solution history – Revisit past problems and copy answers when you’re studying for quizzes and exams. • Built-in calculator – Scientific calculator and unit converter without leaving the app. BUILT FOR UNDERSTANDING Most “homework solver” apps dump one line of text. This app is built around showing the method: scan → read the steps → learn the approach. Use it to check your work, follow along in class, and prepare for tests. Free tier includes daily AI solves; upgrade to Pro for unlimited help and full history.
