When I was growing up, I always liked building things: Lego builds, Minecraft worlds, and then video games in Scratch. I’d make a little game, post it for other kids to play, read the comments, and make it better. Then, when I started high school, I had to spend way more time studying than I ever had, and honestly I just wanted to build things. So I went looking for ways to get good grades while studying less. Khan Academy had an AI tutor in the works, but it was stuck behind a waitlist, so I figured, why not build my own?
After months of launching random stuff, I created an AI tutor called Aceflow. You could feed it anything a teacher assigned—a 30-minute lecture video on YouTube, a blog post, a PDF of the textbook or presentation slides—and it would spin up endless practice questions, with a tutor on the side that explained things the way my teacher did. I built it just for myself, showed it to my friends, then put it on TikTok. It got tons of views on TikTok and thousands of users.

Was I worried people would call it cheating? Not really. I knew how to defend it: A tool like this isn’t so different from well-off families hiring expensive private tutors, except everyone gets one. That part mattered to me. Back in eighth grade, a teacher had me run a little computer science class for about 30 kids with special needs, and once they got personalized attention, they were building games nobody expected of them. That convinced me that kids are capable of so much more than people think, and AI can help scale that level of personalized attention to everyone. That unlocks so much potential.
That first AI tutoring project ended up helping me land part-time roles at BenchSci (one of Canada’s biggest AI companies) and Simple Ventures (a venture firm). More recently, I joined an AI lab at MIT; co-instructed an AI agents course with an MIT professor; and launched CheetahPrep.com, an SAT prep platform that uses AI to adapt to each student.
I’m generally optimistic about how AI will impact humanity, but when other kids’ first reaction is fear, I think that’s an important sign too. It’s a reminder that we should be excited about the future while still being mindful of the risks, working together to make AI work for humanity.
