Questions parents ask
Does Pengi give my child the answers?
No. This is a core design principle, not an afterthought. Pengi uses the Socratic method — it asks guiding questions that help your child reason through the problem step by step. The goal is understanding, not answer delivery. Your child has to do the thinking.
Is Pengi safe for children?
Yes. Pengi is built specifically for K-12 learners (grades 3–11). It focuses exclusively on academic content, carries no ads, and does not collect personally identifiable information. No account is required to start a lesson.
Is Pengi free?
Yes, Pengi is free to use. Your child can start a lesson right now without creating an account or entering a credit card.
What's the difference between Pengi and ChatGPT?
ChatGPT is a general-purpose AI that will answer any question — including your child's homework. Pengi is purpose-built for K-12 learning: it refuses to give direct answers, aligns to school textbooks, supports voice tutoring, and is designed so that every interaction builds understanding rather than bypassing it.
Does Pengi work with my child's school textbook?
Very likely yes. Pengi supports 100+ textbooks across math, science, social studies, and more — including major series from Pearson, McGraw-Hill, and others commonly used in grades 3–11. Browse the full list at pengi.ai/textbooks.
