How it works
More than a prompt. A place to make things.
The idea, build, preview, checks, cost, and teamwork stay visible from the first sentence to the final link.
See it work before sharing
Every product runs in an isolated workspace with preview and security checks, so you can judge the result instead of trusting a block of generated code.
Make it together
Bring friends or teammates into the same project with rooms, files, decisions, and AI buddies that understand the shared goal.
Built for ownership
Your product should outlive the prompt.
Projects begin private and secrets stay outside generated source.
Push source to GitHub or download individual files whenever you need them.
Spend guards, checkpoints, and security scans protect the build loop.
Simple starting point
Start small. Pay more only when the product earns it.
