Describe an app.
An agent builds it.
RI7U4L turns a plain description into a working web app with its own database and sign-in. Watch it take shape in a live preview, ask for changes in your own words, and publish it at its own address when it is right.
Sign up with Google or your email. No card needed to start.
A booking page for my studio: clients pick a class and a time, pay a deposit, and get an email reminder the day before. I need a simple admin view to see who's coming.
How it works
From an idea to a live app, without a project plan.
You stay in charge of what gets built. The agent does the building, on its own machine, and every change is saved as a version you can go back to.
Describe it
Say what the app is for, who uses it and what they need to do. Start from a blank canvas or a starter like a waitlist, a chat or an AI assistant.
Review and refine
The app runs in a live preview while the agent works. Click through it, point at anything you want changed, and ask for it in plain words.
Publish
One click puts it live at your-app.ri7u4l.com, or on your own domain with Pro. Keep improving it and publish again whenever you like.
What you get
Real apps, not mockups.
Every app comes with the parts a working product needs, so what you see in the preview is what your users get.
Its own database
Each app gets a real backend with live data, so lists, forms and dashboards update the moment something changes.
Sign-in for your users
Accounts, sign-up and sign-in are built in, so you can keep pages private and show each person their own data.
Payments
Take payments in your app through Stripe or PayPal, with the money going to your own account.
AI inside your app
Add features that write, summarize, sort or generate images, without signing up for a model provider yourself.
Every version kept
Each change the agent makes is saved. Restore an earlier version, or try an idea on a branch first.
Built for teams
Bring your company in, invite members with roles, and work on the same apps together.
Simple pricing
Pay for the building, not for seats you don't use.
Plans cover your workspace. AI credits cover the agent's work, priced at what the models cost, and any credits you buy never expire.
