From an idea to a live app, in minutes

You describe what you want. 4rth plans it, builds it, checks it and hosts it. You never touch code, servers or a database.

1

Describe it

Write what you want in plain English, or start from a template. One sentence works; more detail gets you closer on the first try.

You write“A bedtime story app. Parents pick an age and a theme, and it writes a new story with a picture.”

4rth plans it

Your description becomes a product plan: the pages, the data each page needs and the actions people can take.

AI builds and checks it

Every page is written for you, then automated health checks look for broken pages and actions that fail.

Publish and share

One click puts it live with a link you can send to anyone. Hosting is handled for you.

Keep improving it

Change anything by sending a message, such as “add a dark mode” or “let users save favorites”. When AI models get better, your app gets better with them.

You ask“Add a button to read the story out loud.”
