Zerano

Read full description

Zerano turns textbook pages into clear summaries, comprehension questions, and targeted review — for students learning independently and parents checking understanding. Designed for students ages 10–14, Zerano helps turn real school material into a simple learning flow built around the textbook itself. For Students Scan → Understand → Practice → Review → Improve • Scan one to three connected textbook pages • Get a clear, age-appropriate summary • Practice with comprehension questions based on the scanned material • Receive instant feedback and explanations • Track concept mastery over time • Review weak or due concepts when they need more practice • Revisit previous scans and retake quizzes Zerano does not just generate a quiz and forget it. It keeps track of concepts that need more work and brings them back for focused review. For Parents When your child says, “I’ve learned it,” Zerano gives you a quick way to check. Simply scan the textbook pages your child studied and let Zerano generate questions from that exact material. You can then quiz your child without having to prepare questions yourself or read the entire lesson first. It is an easy way to see whether the lesson is really understood — and where a little more practice may help. Built Around Real School Material Zerano is not an open-ended chatbot. The learning experience starts with the textbook pages you scan and follows a structured process of summary, practice, feedback, mastery, and review. Personalized Study Settings Adjust the learning experience to suit each study session: • Choose the number of quiz questions • Select the level of summary detail • Set summary and question languages independently • Study across different school subjects Progress That Builds Over Time Zerano tracks learning at the concept level. • See strengths and areas that need more practice • Review weak and due concepts • Focus review by subject • Use spaced review to revisit material over time • View progress across subjects • Return to previous learning sessions in Scan History Points, streaks, and daily goals add light motivation without distracting from learning. Free to Start Start without creating an account. • 2 lifetime scans as a guest • 5 scans per month with a free account • Premium unlocks unlimited scans Core learning features — summaries, quizzes, mastery tracking, and review — are available in the Free experience. Zerano is designed to make studying easier for students and checking understanding easier for parents. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
