Pengi is an AI-powered K–12 learning platform that helps students in grades 3–11 learn directly from their school textbooks. Students get structured lessons, practice sessions, and challenge flows aligned to the exact books used in their classrooms — covering math, science, social studies, and language arts across more than 50 curriculum-aligned textbooks and 500+ lessons.
Pengi organizes learning into three modes: Learn (AI-guided lessons with a live whiteboard tutor), Practice (targeted exercises per skill), and Challenge (timed problem sets for competition prep). Students navigate by textbook chapter and lesson — mirroring the structure of their actual school curriculum. No credit card required; core content is free.
Pengi is designed for students in grades 5–9, ages 10–15, who want to get ahead, catch up, or prepare for AMC 8 and AMC 10 math competitions. Parents use Pengi to support homework without needing to be subject-matter experts. Teachers use it as a supplemental practice tool aligned to their existing textbook curriculum.
Unlike generic AI chat tutors, Pengi is curriculum-structured: every lesson maps to a real textbook chapter so students always know where they are in their learning path. The platform covers competition math (AMC 8, AMC 10) alongside standard K–12 subjects, making it one of the few tools that bridges classroom learning and math olympiad preparation.
It's still in progress but so cool! Suuuuuuper cool. I even showed Pengi to my bro because it's great, and he thinks it's awesome too. I was in the middle of the penguin course — it was cool!
What is this Pengi thing? It's like rlly cool, I get to learn everything from my school beforehand — THIS IS A MIRACLE. IT HAS THE EXACT BOOKS TOO AND IT FREE, MY LIFE HAS BECOME TOO GOOD TO BE TRUE!
As a DC public school parent, I've always struggled to find better learning resources. I mentioned wanting a Diagnostic Test to track my child's math progress, and the team built it right away and invited me to try it. Their quick action shows they're truly trustworthy and committed to helping kids learn.
Pengi mirrors how we teach with AoPS: build intuition, train patterns, and apply under time pressure. It's the ideal at-home training ground for AMC 8.
With Pengi's 3-mode system —Learn, Practice, Challenge— she builds skills step by step, and actually looks forward to it.
I used to guess. Now I solve with strategy—and earning gems keeps me going.
