ReadBuddy is an AI-powered reading companion for children (grades K–5) and their parents. It works with any book your child reads — picture books, graphic novels, or chapter books — and turns every book into comprehension practice, a daily reading habit, and clear progress you can see. SCAN ANY BOOK. QUIZ IN SECONDS. Your child scans a book cover and gets thoughtful, age-appropriate comprehension questions on the spot. 1,500+ popular titles already have curated questions — and it works with any book, no limited library. DAILY RECAP: EVERY QUIZ, FOLLOWED UP The questions your child missed don't just disappear. Every finished book comes back as bite-size follow-up practice — a think-about-it question, a read-it-out-loud passage, and the vocabulary words to master. READ ALOUD & READING SPEED Kids read a short passage out loud and watch their words appear live as they speak. ReadBuddy measures reading speed (WCPM) and tracks fluency over time. Audio is analyzed in the moment, then deleted — never stored or shared. WEEKLY MISSION, STREAKS & REMINDERS Set a weekly reading goal together and track it day by day. If your reader falls behind, a friendly push or email nudge brings them back on track. MADE FOR PARENTS, TOO - Sunday Parent Report — a weekly email recap of books, quizzes, reading speed, and skills to encourage next - Growth tab — trends across books, speed, accuracy, and expression - "For Parents" notes after every quiz: what your child understood, and what to talk about next WHY FAMILIES TRUST READBUDDY - Works with any book — no limited library - Builds comprehension and fluency, not just page counts - No personal or biometric data collected from children - Audio recordings never stored ReadBuddy helps young readers build confidence, curiosity, and critical thinking — ten minutes at a time.
