Brilliant founder Sue Khim launches Koji, an interactive AI tutor that coaches children through math and coding without giving direct answers

This is awesome. I’ve worked with Sue for more than a decade now. She started Brilliant - a learning site for advanced learning - which has now taken all of that decade-long training data and created a helper to make your kids smarter.

It doesn’t matter their level, this adapts to them and brings them along.

Please consider trying it.

AI is making kids dumber.

It should be making them geniuses.

Introducing Koji, the first AI tutor that gets kids to actually think. 👇

We need more AI products that solve society’s hardest problems — like democratizing education and expensive tutoring

This is.. well.. brilliant 😉

My son has been using this and loves it.

“We think AI is bad for kids so we invented an AI so they don’t use AI”

We’re tutoring the next 1000 learners for free this summer. See how far your kid can go in math and coding!

Comment what you want your kid to learn, and we’ll send you an invite to try Koji for free.

Jensen Huang talked about how a real-time AI tutor is making personalized, one-on-one instruction widely accessible.

Instead of giving answers, it coaches step-by-step, adapting in real time.

What was once expensive private tutoring is now becoming available to anyone as they learn.

I'm such a huge fan of what @suekhim and the Brilliant team have built.

When every kid in every country grows up with a 1:1 personalized AI tutor, we'll realize how much potential we really have.

@suekhim If I had this in school maybe I’d be doing something more with my life than posting stupid stuff on 𝕏

@chamath AI will create enormous value in education, but the winners may not be the tools that answer questions fastest. They may be the ones that compound a child's ability to reason, solve problems, and learn independently over time.

Koji is trained by learning experts from MIT and Harvard.

He can see everything you’re doing and respond in real-time.

Koji points, sketches, and annotates, like a real tutor sitting next to you.

BRILLIANT!

Another CP and JCal collab... doing important work in the world AND building an extraordinary business.

@Jason Thanks for being a Day 1 supporter of this vision! This wouldn’t exist without you.

Tutoring is the gold standard for learning, but has been out of reach for most people.

We couldn’t be more excited to bring down the cost by >95% and make it accessible to everyone.

"No need to teach children how to code, because AI writes all the code now. Children should learn to detect mistakes in AI slop code." 🤪

Brilliant and amazing data harvesting tool 😈

I feel the real problem of gradual disempowerment isn’t whether AI can help kids learn. It’s that AI is making kids wonder why they should learn at all when AI can already do better than human experts?

American kids can’t read or do math anymore.

90% of parents think their kid is at grade level. Only 28% are.

And now, kids are addicted to AI for cheating.

That’s why we built Koji to coach you to think, instead of doing the thinking for you.

AI is increasing the need for clear thinkers and problem solvers.

Once school is over, no one will ask you to find the interior angles of a pentagon.

But the part of your mind that math and coding trains is something you’ll use forever.

@suekhim I wanna see Koji teach people how to get into crypto. Now THAT is bullish.

Schools are inflating failing grades, getting rid of hard classes, or convincing everyone that tests don’t matter.

We’ve lowered standards, right as AI is raising the bar for jobs and learning.

We have a different message: Have high standards.

@suekhim Real-time models are very expensive to run. How are you able to offer this so cheaply to students
