ChatGPT vs Pengi: Which AI Actually Helps You Learn?
There's a big difference between getting an answer and understanding how to solve a problem. ChatGPT is a powerful general assistant — but it's built to answer, not to teach. Pengi is built for students: it guides you through each step until the concept clicks.

Voice + whiteboard in real time.
Struggle with showing your work? Pengi's real-time voice tutoring lets you talk through problems while using a shared whiteboard — the closest thing to a human tutor at 2 AM.
Works where you already study.
The Pengi Chrome extension overlays directly on Khan Academy and other learning sites. No tab-switching, no copy-pasting. Help appears right where you need it.

Frequently Asked Questions
- Can I use ChatGPT for homework?
- You can, but ChatGPT typically gives you the final answer rather than walking you through the reasoning. This means students often copy the answer without understanding the concept — which shows up on tests. Pengi is designed specifically to guide students step-by-step so they build real understanding.
- Is Pengi better than ChatGPT for math?
- For learning math, yes. Pengi is aligned to 100+ real K–12 textbooks and guides students through each problem with interactive steps, a real-time whiteboard, and voice tutoring. ChatGPT can solve math problems but is not designed for guided learning or curriculum alignment.
- Does Pengi give answers to homework?
- No — that is the key difference. Pengi never just gives the answer. Instead, it asks guiding questions, highlights where a student went wrong, and walks them through each step. The goal is understanding, not answer delivery.
- Is Pengi free to use?
- Yes, Pengi offers free core access including lessons and guided practice. A premium tier unlocks unlimited voice tutoring sessions, advanced problem sets, and priority support.
- What subjects does Pengi cover?
- Pengi covers Math (arithmetic through pre-calculus), Science, Social Studies, and ELA for grades 3 through 11. Content is aligned to real textbooks used in US classrooms, including popular series like Go Math!, Eureka Math, and more.
