Why I built Tavi

Tavi's founder Justice Erolin on why an 'anti-AI AI' — one that asks questions instead of answering them — is what his three kids actually needed.

TL;DR

  • I'm a parent of three, and I'm the go-to homework helper in our house — especially for math.
  • Handing over the answer was never the point. Asking the right question was.
  • When I travelled and couldn't be there, I wanted something that coached the way I did. So I built it.
  • Tavi is, in a way, an anti-AI AI. It doesn't give answers. It asks questions. That's the whole thing.

I love math

Not because of numbers and variables. Because of what math teaches. It trains kids to take a big, messy problem and break it into smaller problems they can actually solve. That's a life skill dressed up as a worksheet.

At home, I'm the go-to parent for math homework. My kids know where to come. And I've learned something doing that work, over and over, that I didn't expect to learn.

Teachers are doing a different job — and they should be

I want to be careful here, because I have a lot of respect for teachers. They have one of the hardest jobs I can imagine.

A teacher isn't working with one kid. She's working with twenty. Or thirty. In our household of three, getting all three to focus at the same time is already a small miracle. Now imagine doing that for a room full of them, every day, for a year.

When you're teaching at that scale, drills and repetition work. They create structure, they reach the whole room, and they get everyone to a baseline. I'm not against that. It's the right tool for the room a teacher is standing in.

But the room I'm standing in at homework time is different. I have one kid at a time. At that scale, I can do something teachers rarely have the minutes or the student ratio to do.

Giving the answer was never the point

"Teach a man to fish" is older than me, older than all of us. But it kept showing up during math homework.

Because if I just gave the answer, yes, the homework got done and the score went up. But the next night, the same kid got stuck on the same kind of problem, and I'd gotten them no closer to the finish line. I'd fed them once. They were still hungry.

What worked — and kept working — was asking questions instead of answering them. What do you know so far? What is the problem actually asking for? Where does this piece of it come from? What would happen if you tried that?

It was slower in the moment. But it was repeatable. And more importantly, they started asking those same questions on their own.

Then I got on a plane

I travel a lot for work. One week I was in England. My kids were in Los Angeles. By the time my day started, their homework was already over. By the time their day started, I was in a meeting.

That was the moment the idea cracked open. Could I bottle this? Could I build something that asked the questions I'd ask — even when I wasn't in the room?

An anti-AI AI

Here's the strange part. I asked my kids what they think about AI for homework. All three of them, without hesitation, said they don't want an AI that just hands them an answer. They know those tools exist. They've tried them. They don't want them.

They don't feel like they're learning anything when a finished solution shows up on the screen. They feel like they cheated themselves. They want to actually understand.

So Tavi is a little contrary, for an AI product in 2026. It doesn't give answers. That isn't marketing — it's a code-level guardrail. When a kid asks Tavi for the answer, Tavi asks them a better question.

It turns out the thing I was already doing at the kitchen table has a name. It's about 2,500 years old. It's called the Socratic method. Combining that ancient teaching posture with modern AI is how we give every kid a patient, one-on-one coach — one that never gives up and never gives in.

What this blog is for

Tavi is in private beta right now, with a small group of families testing it and shaping it with us. This blog is where I'll write about what I'm learning along the way — about homework, about AI and kids, about how thinking actually develops.

You'll see a few themes come up over and over:

  • The Socratic method, for kids and at home.
  • AI and kids — safety, dependency, and the homework conversation.
  • Math stuck points, grade by grade.
  • Homework help without doing it for them.
  • How kids actually learn.

I won't pretend to be an expert. I'm a parent with three kids and a strong opinion about what thinking is worth. When I cite research, I'll show my work. When I share a coaching exchange, it'll be composite and anonymized — my kids deserve their privacy, and so do yours. When I don't know, I'll say so.

If you're a parent wrestling with any of this, I'd love to have you along. We're figuring out how to teach the next generation in a world where answers are free. Thinking is the part that isn't.
