Frequently Asked Questions
- What is a voice math tutor for kids?
- A voice math tutor lets students talk through math problems out loud and receive spoken guidance in return — just like working with a human tutor sitting beside them. Pengi's AI voice tutor listens to your child's reasoning, asks guiding questions, and helps them arrive at the answer themselves without ever just saying it out loud.
- Is there a free voice AI tutor for math?
- Yes. Pengi offers free voice math tutoring for K–12 students — no credit card required. Students can start a live voice session immediately on pengi.ai or through the free Chrome Extension on Khan Academy and IXL.
- How is voice tutoring better than typing for kids?
- Many students — especially younger ones — find it easier to explain their thinking out loud than to type it. Speaking activates different reasoning pathways and often reveals exactly where a student's understanding breaks down. Pengi's voice tutor picks up on these moments and responds with targeted questions that address the root confusion.
- What math topics does the voice tutor cover?
- Pengi's voice math tutor covers arithmetic, fractions, decimals, pre-algebra, algebra, geometry, precalculus, and statistics for grades 3 through 11. Content is aligned to 100+ real US textbooks so the guidance matches what students are learning in class.
- Is Pengi safe for young children to use?
- Yes. Pengi is designed specifically for K–12 students and maintains a focused, age-appropriate scope. Unlike general AI assistants, Pengi stays on educational content and is safe for children to use independently or alongside a parent.
- Does the voice tutor work on Khan Academy?
- Yes. Install the free Pengi Chrome Extension and the voice tutor activates automatically on Khan Academy, IXL, Scratch, and PhET. It reads the current exercise and provides real-time spoken guidance without ever revealing the answer.
