Coming soon
The HeyOtto Creator Program is on its way.
The Marketplace is just the beginning. We're building a full Creator Program for educators, parents, and kid creators who want to share their work, grow an audience, and — eventually — earn recognition for what they build.
Enhanced creator profiles
A dedicated page for every approved creator, with their full resource catalog and community stats.
Classroom collections
Teachers will be able to build and share classroom-specific bundles, shareable with parent approval.
Personalized recommendations
Otto gets smarter about what your child will love — surfacing resources based on their interests and learning goals.
Built something amazing? Here's how sharing works.
Your child creates in chat, you approve with one tap, and HeyOtto handles the rest — free, transparent, and designed for families.
Build & get parent approval
It starts in chat — your child builds with Otto, then you approve before anything goes public.
- 1
Create it in chat
Your child tells Otto what they want to build — a game, app, tool, drawing page, or anything else they can imagine. Otto builds the interactive artifact in a panel right next to the chat, and it's automatically saved to their Projects.
- 2
Test & refine
OptionalThey can play with it, break it, and ask Otto to change anything. Each update creates a new version — and every version stays saved.
- 3
Request to share publicly
When they're proud of it, they tap the share icon in the artifact header and choose "Ask a grown-up to share." You'll get an approval email.
- 4
You approve the share
Your email includes Approve and Block buttons — tap Approve to activate the public link. No sign-in required; it works right from your inbox.
HeyOtto review
After you approve, our team makes sure every public creation is safe, age-appropriate, and worth sharing.
- 5
Automated screening (same day)
We scan for immediate red flags — profanity, explicit content, and spam — before anything moves forward.
- 6
Human review (3–5 business days)
Our team reviews for safety, age-appropriateness, educational quality, values alignment, and design.
- 7
Feedback or approval
If changes are needed, you'll get detailed feedback and 14 days to revise. Most resources publish within 7–10 business days total.
