Two different jobs

What is HeyOtto? What is Replit?

One is built to help kids learn by building. The other is built to help people build and launch software.

  • HeyOtto

    What it does

    Turns a kid's idea into a working game, app or website. Kids describe it, Otto builds a first version with them, and they explore, change and debug the real code. Every project saves to Projects, and parents can see it.

    Where it stops

    Projects stay in HeyOtto, with no external APIs or outside connections, so there's no hosting, databases or outside services.

  • Replit

    What it does

    A browser-based platform where Replit Agent builds apps from a description. It includes a full code editor, built-in hosting and databases, and 100+ integrations like Stripe and Google Workspace.

    Where it stops

    Isn't built for kids: it's 13+, the user creates their own account, and there's no parent dashboard.

Which fits your kid?

The right tool depends on age and goals

Here is how the choice looks at each stage.

01 / 04Under 13

For kids under 13

Replit's terms don't allow users under 13. HeyOtto lets them build real projects now, with you able to see everything.

Which should you choose?

Choose the tool that fits today

  • Choose HeyOtto if…

    For kids and teens 8–18
    • Your child is under 13, or just starting out
    • You want an AI that explains and asks questions
    • They want games, apps and websites without setup
    • You want to see their projects and conversations
    • You want the same safety controls as the rest of HeyOtto

  • Consider Replit when…

    For ages 13+, with permission
    • They are 13 or older and have your permission
    • They want to put a project live on the internet
    • They need databases, logins or integrations
    • They can test, debug and review AI-written code
    • You have agreed on rules about data and sharing

Same safety, every feature

Coding doesn't switch off HeyOtto's safety

Kids and teens code inside the same HeyOtto account, with the same filters, controls and alerts as everything else in HeyOtto. That is the biggest difference from a general development platform.

  • Every request and response passes multiple layers of safety checks before your child sees it
  • Answers adapt to the age the parent sets
  • Parents choose which topics are off-limits
  • Real-time safety alerts, and high and critical alerts can't be turned off
  • Parents can read conversations, including questions asked while coding

No ads, data never sold

No ads or ad pixels in the logged-in kids' experience, and we never sell data.

Same protections for teens

Teens 13–18 get the same filters and parent visibility as younger kids.

Growing up

Can kids move from HeyOtto to Replit later?

Yes. Skills built in HeyOtto, like variables, functions, events, conditions and debugging, carry straight over. The aim is a kid who can use more powerful tools well.

Before a project goes live

AI-written code can have bugs or security holes. Agree on rules first: no personal info, review the code, and never share passwords or API keys.
