I couldn't find a way to teach my 2-year-old about AI — so I built one with my own product.

I'm a part-time founder building Michii.dev (http://michii.dev/), an AI cofounder for people who want to build, run and market a business without a team behind them. I also have a full-time job and a 2-year-old. Time is the one resource I don't have. So instead of writing about what my product could do, I spent a couple of late nights actually using it on two problems that were bugging me personally.

1. A bilingual (JP/EN) game to teach my son about AI

Last week I went looking for a storybook or game to introduce my 2-year-old to AI agents, robots, machine learning — the world he's going to grow up inside. I couldn't find anything aimed at his age. And I definitely couldn't find one in both Japanese and English, which matters to us: we're a Vietnamese family living in Japan, and I want him comfortable in both languages.

So I built it. Visual-first, almost no text, made for a toddler's attention span. Last night I sat with him before bed and tried to explain what an AI agent is using it — and he actually stayed with it and enjoyed it. That was the moment the whole thing felt worth it.

If you're a parent — especially in a bilingual household — I'd genuinely love to know whether it lands with your kid.

2. A Japanese pronunciation coach for myself

The second one is pure self-interest. I've lived in Japan for years and my Japanese is functional, but pronunciation is the part that never caught up. There are great tools like BoldVoice for English learners — I couldn't find the equivalent for Japanese, giving real-time feedback on how you actually sound. So I built that too.

Why I'm posting this instead of a traffic number

I've read a lot of the "$X/mo, zero employees, AI runs the whole company" posts on the internet.

What I actually care about is the part those posts skip: can one person turn an idea into a launched product that people actually use — with no team behind them? That's the bet behind Michii. You describe the business you want in a prompt, and the agents build it, put it live, and go find your first users.

That last part is the one that surprised me. For the kids' AI game, Michii's agent went out, found kindergartens that might want to use it, and emailed them — and a school in Finland actually wrote back. I didn't find that lead or write that email. An agent did.

And I think that only matters more from here. The number of solo founders is going to keep growing — people with an idea and the drive but no team to make it real. That's who I want Michii to serve: an agent team that builds your product, markets it, finds your potential users, and sends the cold emails to reach them — plus the infrastructure underneath: payments, servers, domains, all of it. You bring the business idea; Michii handles the rest. The leverage of a whole team, for one person.

Both apps were built with Michii. That's the honest pitch. Not a screenshot of an MRR chart — just: here's what I built with it this week.

I'd love feedback on any of it: the kids' game, the pronunciation app, or the idea behind Michii itself. I'll be in the comments for the rest of the day.

    Reading this, I kept coming back to the fact that your examples aren't really products—they're evidence.

    The kids' game and pronunciation coach don't just demonstrate what Michii can build. They demonstrate the kinds of problems a solo founder can choose to solve once execution becomes less of a constraint. That feels like a much stronger story than simply saying "AI builds apps."
